How to reduce background noise and echo in iphone voice memos

Recording quality audio on the iPhone is pretty easy with the Voice Memo app. But, the background noise is still an issue. Even with the latest models of the iPhone, the noise is an issue. Unwanted background noise makes the voice memos and audio recordings look unprofessional. But, there are some workarounds you can remove background noise from the audio on the iPhone.

Here is how to remove background noise on audio recorded using iPhone.

Remove Background Noise from Audio Using Voice Memo

The Voice Memo app on the iPhone has got a new feature with iOS 14 update that helps you improve the audio. Apple offers to enhance the voice memo recorded on iPhone. It is with the new background noise removal feature. Here is how you can remove background noise from Audio on iPhone using the Voice Memo app.

1. Open Voice Memo app on the iPhone.
2. Record a voice, or tap on an existing voice memo.
3. Tap on three dots menu icon.
4. Tap Edit Recording.
5. From the editing screen, select the enhance button (magic wand icon) on the top-left edge.
6. Tap Done to save.

You can remove the voice reduction from any recording on the Voice Memo app. Apple calls the feature “Enhancement”, and the noise reduction is just one of its features. Though it is not perfect in noise reduction, you can use it when you want to remove minor hissing noise from the recording. In case you do not have the latest iOS 14 update, you can use third-party apps for background noise removal purposes on iPhone.

Use Third-Party Apps for Audio Noise Reduction on iPhone

The new enhancement feature for Voice Memo is now available only on iOS 14 and newer. Are you using an iPhone with older iOS? You might need to use third-party apps for noise reduction. There are tons of apps available to remove background noise from Audio on iPhone, in case you are running older iOS versions. Here are some of the best voice noise reduction apps for the iPhone.

Denoise – Audio Noise Removal

Your iPhone’s Voice Memos app records audio in a compressed format by default, saving storage space on your iPhone but reducing the recording quality. You can switch to a lossless mode for maximum fidelity.

Your iPhone, by default, records voice memos in a compressed format. However, if that doesn’t cut the mustard for you, there is an option to switch over to a lossless recording instead. It’s not clear what file format your iPhone uses here, but suffice it to say it’s going to take up more space than a compressed AAC file. Bear that in mind, but considering most voice memos are probably pretty short, we don’t think it’ll be of huge impact.

How to Choose Lossless Recordings

As always with iOS, the setting that we are looking for is in the Settings app. Open it and tap “Voice Memos” to get started.

Next, tap “Audio Quality” towards the bottom of the screen.

The next screen offers two options. Tap “Lossless” for the best sound quality from your recordings. If space is your main concern however, we’d suggest sticking with “Compressed” and leaving everything as it is.

When you’re recording audio on your device, there are several ways unnecessary noise can creep into your clips. Fortunately, the preinstalled Voice Memos app on your iPhone or iPad can clean up background noise and echos with a single tap. Here’s how to use it.

Apple introduced the Enhancing Recording in the Voice Memos app with iOS 14 and iPad OS 14. Therefore, make sure to update your iPad or iPhone to the latest firmware version before proceeding. If you’ve uninstalled the Voice Memos app, you can download it again from the App Store.

Now, launch the “Voice Memos” app. Use Apple’s built-in Spotlight search if you can’t find it on your iPhone’s home screen or App Library.

Select the voice recording you’d like to edit. Once open, tap the three-dot menu icon on the left side of your screen.

In the following menu, select the “Edit Recording” button.

In the top left, tap the magic wand-like icon.

Within seconds to a minute, depending on your recording’s length, the Voice Memo app will process the audio to automatically “reduce background noise and room reverberation.” When it’s done, the button will be highlighted.

Play the recording to preview the edits. If you’re satisfied, tap “Done” to save the modified clip.

By default, the Voice Memos app overwrites the original audio file. To save the changes as a new separate clip, you can create a duplicate before applying the “Enhancing Recording” filter.

To do that, open the audio clip and then tap the corresponding three-dot menu icon. This time, select the “Duplicate” option instead of “Edit Recording.”

The app will immediately create and add a duplicate of the original audio file in your list of recordings. It will have the same title with a “copy” appended at the back. You can rename a file by tapping it once to reveal options and then selecting its name to edit it.

Because Enhancing Recording relies on automated algorithms to distinguish the noise and echo from the audio, it won’t always deliver accurate results and can be a hit or miss.

In addition to using the Enhanced Recording feature, you can consider recording audio in a Lossless format, which will take up more storage space but produce richer quality.

Your iPhone’s Voice Memos app is an easy tool for quickly recording lectures at school, jam sessions at the studio, or just verbal notes to yourself. While it’s a straightforward app, there are several hidden features you might not know about that can improve the quality of your recordings.

One feature that may be news to your ears is the ability to record in lossless audio quality. Another lets you use an external microphone to get higher-quality stereo recordings. Without those, however, there’s an even easier setting that you can toggle on to improve any of your saved audio files in Voice Memos.

Apple introduced an “Enhance Recording” feature in iOS 14 for Voice Memos, which uses machine learning to reduce background noise and echoes and make the recording more clear and easier to listen to. If you’re someone who has trouble getting excellent quality audio recordings off your iPhone, this is a mechanism that you should definitely test out.

In Voice Memos, tap on an existing recording to expand your options. In the expanded playback controls, tap the ellipsis (•••) icon to the left, which will bring up the actions sheet. From the list, select “Edit Recording.”

Here, you can trim your recording, but you can also enhance it with a single tap. In the top left of the editor, you’ll see a magic wand button, which is the Enhance Recording feature. Tap that icon, and the button’s background will turn blue to let you know that it’s activated.

Now, tap on the play button to listen to the recording. As mentioned before, your iPhone will do its best to minimize background noises and other disruptions, such as echoes. If you want to compare the sound quality, disable the enhanced recording and play the file without it.

Comparing the before and after is essential since Enhance Recording doesn’t always “enhance” the audio in every sound file; it may make some sound recordings worse. Whenever you’ve chosen the best version, with or without the magic wand selected, tap “Done” to save the edits.

If you change your mind about the sound recording, you can always go back into the voice memo editor and turn off Enhance Recording for the file. Just like edits in the Photos app aren’t forever, edits in Voice Memos can be reverted.

The Voice Memos app allows its users to record short voice notes and reminders or more extended audio like interviews, it has been a part of the iPhone iOS since the beginning.

Since the release of iOS 14, users can reduce background noise and enhance an iPhone voice memo with a single tap within the Voice Memos app. Prior to iOS 14, there was no way to improve these recordings’ quality without exporting the audio file to another program or app.

Apple’s Voice Memos app in the iOS 14, iPadOS 14 and macOS 11.0 Big Sur software updates includes a brand-new feature which was designed to improve the sound quality of your recordings, including existing ones. Follow along with us as we show you how to use Voice Memos’ Enhance Recording feature to reduce background noise and room reverberation.

Enhance Recording in Voice Memos

As mentioned earlier, the extremely handy Enhance Recording feature was added to the Voice Memos app on the iPhone, iPad and Mac with the iOS 14, iPadOS 14 and macOS Big Sur updates which were previewed during Apple’s WWWDC keynote on June 22, 2020.

At the time of this writing, the updated Voice Memos software was available through beta testing of iOS 14, iPadOS 14, and macOS 11.0 Big Sur. The app will become available to everyone with a compatible device once Apple releases these updates publicly in the fall.

According to Apple’s description of the feature:

The most popular audio recording app in the world gets new tools for organizing recordings. An all‑new Enhance Recording feature lets you improve the sound quality of your recordings with a single tap.

Follow the tutorial ahead for step-by-step instructions walking you through the process of using Voice Memos’ Enhance Recordings feature to boost the sound quality of your recordings.

How to use Enhance Recording in Voice Memos

Follow these steps to enhance recordings in Voice Memos:

1. Open the Voice Memos app on your iPhone, iPad, iPod touch or Mac.
2. Capture a new audio recording or choose one of your previously saved recordings on the list to reveal options, then hit the three-dotted menu at the leftmost side below the recording.
3. Choose Edit Recording from the popup menu.
4. Tap the Enhance Recording icon near the top-left corner of the interface.
5. Tap Done to save the changes.

That’s it, on-device machine learning will attempt to do its best to minimize background noise and reduce room reverberation as much as possible. Depending on the audio quality of your source recoding, you may experience a minor or major difference after applying Enhance Recording processing. Keep in mind that this is a non-destructive editing feature — you can easily revert back to the original recording by deselecting the Enhance Recording icon.

The Enhance Recording feature is unavailable in Voice Memos for Apple Watch. That’s nothing to write home about because the watchOS app is limited to capturing audio recordings. The editing features are (for now) reserved for the app’s Catalyst version on iOS, iPadOS and macOS.

Who needs Voice Memos’ Enhance Recording?

As a journalist, I use Voice Memos on a somewhat regular basis for capturing my thoughts, conducting quick interviews I may later refer to and so forth. I’ve been very pleased with the sound quality in Voice Memos, especially on the iPhone thanks to its multi-microphone array.

While I’ve only captured a couple of voice memos with my Apple Watch and computer, I could tell instantly that the sound quality was not as good as on the iPhone, which is quite understandable given the less powerful microphones in the Apple Watch and the Mac.

Voice Memos in iOS 14 has an ‘Enhance Recording’ feature that reduces background noise and echo to make voices more clear.

Kind of fun to imagine if Apple were to use this for Podcasts down the road…

I can clearly see the benefits of using Voice Memos’ Enhance Recording feature to make my Apple Watch and Mac recordings sound better, but even the iPhone owners will benefit from machine learning-powered reduction of background noise and room reverberation.

Other Voice Memos improvements

The iOS 14, iPadOS 14 and macOS 11.0 Big Sur software updates bring a few other quality-of-life improvements in the Voice Memos app (which is now based on Apple’s Catalyst framework for feature-parity across platforms). For example, you can organize your recordings with folders or mark them as favorites so you can quickly access them later.

With a new Smart Folders feature, you can set Voice Memos to automatically organize your recordings. For instance, the system may group your Apple Watch recordings, recently deleted recordings and favorites. If you use Voice Memos on a regular basis, auto-grouping of recordings makes it a hell of a lot easier to stay organized.

Part of iOS since the beginning of the iPhone, the Voice Memos app allows you to record short voice notes and reminders or more extended audio like interviews.

Despite its intended use, until recently, there was no way to improve these recordings’ quality without exporting the audio file to another program. But starting in iOS 14, you can enhance an iPhone voice memo with a single tap within the Voice Memos app.

The new Enhance tool uses artificial intelligence to reduce background noise and reverberation. There are no dials or sliders to fiddle with; it’s either on or off for each voice recording. You can enhance any voice memo – a new one or an older memo you recorded long ago.

Any changes are fully reversible, and you can hear the changes immediately. You can also go back at any time and turn Enhance on or off.

Here’s how to enhance your voice memos.

How to enhance an iPhone voice memos recording

1. Start the Voice Memos app.

2. Tap the voice memo you want to enhance.

3. Select the three-dot icon to the left of the playback controls.

4. In the pop-up menu, choose “Edit Recording.”

5. At the top left, tap the Enhance icon, which is shaped like a magic wand.

6. If you like the changes the Enhance button makes, leave the button enabled, and then tap “Done.”

7. If you think the Enhance tool makes the file worse, turn off Enhance before tapping “Done.”

What you need to know

• The iPhone, iPad, and Mac will get an enhanced Voice Memos app.
• The feature will remove echoes and background noise.
• New folders, smart folders, and more will also be added.

Apple announced iOS 14, iPadOS 14, and macOS Big Sur during its WWDC event last week but as ever some changes couldn’t get as much attention as others. The Voice Memos app is a good example of that with some new features coming out of the woodwork now people are testing the first round of betas. Top of the list is a new Enhance Recording feature that promises to reduce background noise and echoes.

It’s clear why such a feature would be beneficial to the Voice Memos app and anything that makes memos easier to listen to is always a good idea. The feature was first spotted by Federico Viticci who pondered whether it could also be used for podcasting.

Voice Memos in iOS 14 has an ‘Enhance Recording’ feature that reduces background noise and echo to make voices more clear.

Kind of fun to imagine if Apple were to use this for Podcasts down the road.

As 9to5Mac points out, there’s more going on in these updates than that, though. Users will finally be able to put memos into folders with a smart folder feature automatically sorting them based on whether they were recorded on an Apple Watch etc. Users will also be able to favorite specific recordings, too.

Apple has already released betas of iOS 14, iPadOS 14, and macOS Big Sur to developers with public betas set to arrive next month. Everyone else will have to wait until September or thereabouts before they can enjoy everything these updates have to offer.

It’s not the fanciest or the most elaborate improvement that’s come with iOS 14, but it could be the one you use most often. Apple has added one-touch enhancements to all your audio recordings done in Voice Memos.

There are dozens, possibly hundreds of audio recording apps for iPhone, but Apple has raised the bar for all of them with how it’s improved the stock Voice Memos app that comes in iOS 14. Despite the name making it seem like a Dictaphone-style recorder that’s only useful for short dictation, Voice Memo is a full audio recording app.

And it’s now a full audio app with Enhance Recording. Again, despite the name making it sound as if this is a way to improve the quality of anything you record from now on, it’s more than that.

Enhance Recording will improve, or at least attempt to improve, any audio you record now in Voice Memos — or have ever recorded into it. It doesn’t have the kind of fine tuning that a broadcast-quality app would bring, but it will make your next podcast recording sound better.

How to use Enhance Recording in iOS 14

1. Record new audio or tap to select an existing recording
2. Tap on the ellipses icon that appears at the bottom left of the recording’s entry
3. Tap Edit Recording from the menu that appears
4. Tap the magic wand icon toward the top left of the screen
5. When it’s highlighted, tap Done at bottom right

Apart from the magic wand icon highlighting in blue, nothing appears to happen. Tapping Done just takes you back to the list of recordings.

However, if you now tap the Play icon in that recording’s entry in the list, you will normally hear a difference. Your results will vary, and actually they may vary enormously.

What the Enhance Recording does is use Machine Learning to attempt to cut out everything you don’t want to hear, while keeping everything you do. So it is able to remove, or at least reduce, sounds such as background noise.

Similarly, it will do its best to get rid of room reverberation. That’s the faint echo you can’t hear in the room, but which gets faithfully recorded as it bounces back off the walls around you and into the microphone.

You can get very clear improvement, but don’t let us oversell it. At least as often as you hear a dramatic difference, you may not hear any difference at all.

What’s least likely to happen is that you won’t like what you hear. However, in that case you’re in luck because there is one more part to this feature — an undo.

Unlike a regular undo when you might have to remember to choose it right now, you can go back to an enhanced recording at any time and remove those enhancements.

How to remove enhancements

1. Record new audio or tap to select an existing recording
2. Tap on the ellipses icon that appears at the bottom left of the recording’s entry
3. Tap Edit Recording from the menu that appears
4. Tap to deselect the magic wand icon toward the top left of the screen
5. When it’s no longer highlighted, tap Done at bottom right

This turns off the enhancements completely. You’ll immediately be able to hear the audio revert to the way you originally had it.

What’s happening with enhance audio

The fact that you can add it and remove it so easily, and the fact that you don’t have to wait while the audio is analyzed, makes it seem as if Enhance Recording is a filter. Effectively it is, it’s like adding a gauzy color over a photo and then removing it later.

Except if the Enhance Recording icon is highlighted when you share the audio, it is the improved recording that is sent. You recipient doesn’t have to have Enhanced Recording, doesn’t have to have iOS 14, and doesn’t have to have Voice Memo.

What you can’t do

Voice Memo remains a basic audio recording app. Aside from an option to crop or trim the audio — to remove the start or end of a recording — there are no editing features.

To do more on iOS, you need something like the Ferrite audio editing app. However, you can still pass the enhanced Voice Memo recording to that.

And you don’t have to stick to iOS, either. While you can always share an audio file from any iOS app to anywhere you want, Voice Memo is also on macOS.

Apple announced iOS 14 and macOS 11 Big Sur during the WWDC event last week and with both updates now in the hands of developers in beta form, we’re learning more and more about them.

One of the things we’re learning is the unannounced improvements that have gone into the Voice Memos app on iPhone, iPad, and Mac.

One of those improvements is a simple one, but one that could make a big quality of life difference – folders. Users will be able to organize their memos into different folders, making them more organized.

Part of that is a new Smart Folders feature that will automatically group things like favorite memos, those recorded on an Apple Watch, and more. The Favorites feature itself is new, too.

Perhaps most interesting is the arrival of Enhanced Recording, though. As spotted by Federico Viticci, Enhanced Recording hopes to reduce the amount of background noise and echo in a recording to make it easier than ever to hear and understand the note you just created. It seems to work, too.

The other day one of my friends in the office wanted my help in removing background noise from the

(I am usually the go-to guy for all such problems at home and office, as you can imagine). I could have given him names like Sony Vegas or Adobe Premier Elements, but these tools are heavy and more suited for a professional video editor. Plus, they cost a fortune if anyone wants to use them after the 30-days trial period.

So, he needed free tools to get the job done and that’s exactly what we are going to show in part 1 of this series. In this article we’ll take up background noise removal from an audio file using the powerful program called Audacity. In part 2, we’ll show how to do the same on a video.

Cool Tip: Did you know you could extract audio from a video using Audacity? Do check it out.

The Overall Approach

We will use two tools – Windows Movie Maker and Audacity – for the task. In the current article we will see how we can process just an audio file and remove the background noise while in the next one, we will see how we can extract the audio files from a video and stitch them back again once processed.

Working on the Audio Track

Once you have installed Audacity on your computer, open up the application and load the music file you want to process. Having done that, follow these steps to remove the background noise.

Step 1: Listen to the entire audio file and make a note of the area where you hear the background noise. Make sure you select an area with maximum background noise. Make use of Audacity itself to listen to the file and make a selection through a simple click and drag way on the wave graph.

Note: A segment of just the background noise is very important for the tool to work. If you don’t have it in the current video, make sure you do some recording of just the background noise next time you make a video. This will give you the best output for the processed audio.

Step 2: Having done that, Navigate to the Effect menu and select the option Noise Removal.

Step 3: Here, you will see the button Get Noise Profile. This button is useful only if you have not selected the sound segment already.

Step 4: When using for the first time, I recommend you try out the default settings that are displayed in the same window. They are ideal for most scenarios. But as you work on the tool, you can use trial-and-error to explore the different variations of the settings.

Step 5: Now all you need to do is click on the OK button and let the tool do its magic. Audacity will remove most of the background noise from the soundtrack and you can go ahead and save it as a new MP3 file on your hard drive.

Still thinking of getting the Adobe Premier Elements? Buy it from Amazon at $89.00.

Conclusion

So that was how you can remove the background noise from an audio file using the free and useful Audacity. Don’t be afraid of messing around with the different settings available. Audacity is a very powerful tool and you should explore it as much as you can.

While the result might not be perfect, it certainly does a decent job of cleaning up the background noise.

So try out the trick on some of your personal recordings. Also, don’t forget to join us when we show you how you can use the trick to remove background noise from your Video files.

2. Navigate to the bottom right corner, where you’ll find the Audio Effects icon. Once you’re in the Audio Effects folder, select Equalizer. This will allow you to begin the process of deleting or muting each unwanted sound manually, one band at a time.

3. After you click Enable, begin playing your selected audio track, adjust the volume up and down for each individual band, until you find the specific band that has to be muted. (The disruption could be in one or multiple bands, so keep repeating this process to make sure that the sound is gone entirely.) Don’t forget to turn the other bands back up after you isolate the one you want to delete.

Apple introduced a number of changes to Voice Memos in macOS Big Sur, including Enhanced Recording and Smart Folders. Here’s how to get to grips with the latest add-ons to the memo-recording software.

As part of the shift towards Mac Catalyst apps in macOS Big Sur, Apple has updated its Voice Memos app on both iOS 14 and macOS simultaneously with the same new features. The changes make Voice Memos a more powerful tool for quickly making voice notes, from both your iPhone and the Mac itself.

These features covered a few areas, including improving the audio recordings themselves and to better organize recordings for later retrieval. While the features are largely the same as the iOS 14 variant, the nature of macOS Big Sur’s interface means they function slightly differently in the app on a Mac.

The changes are good enough to make the voice recordings better, but by no means does this turn Voice Memos into a bigger audio processing tool like Logic Pro X or GarageBand. Think of this as more quality-of-life improvements to a solid productivity tool.

Enhanced Recording

As the name suggests, the new Enhanced Recording option can make an audio recording much clearer to use, by reducing the background noise and any reverberations. This chiefly makes it easier to listen to a recording that was performed in a busy environment, or to better hear a more softly-spoken voice.

This is intended to reduce the possibility the listener has misheard or misinterpreted the memo’s contents, which makes it useful for those creating typed transcriptions.

How to enhance a Voice Memo in macOS Big Sur

• Select the recording in the sidebar.
• Click the Edit button in the top-right corner.
• Click the Enhance button, which has the magic wand icon.
• Preview the audio by pressing the Play button.
• Click Done.

The same procedure can also be performed to remove the enhancement to the entire audio clip. The enhancement is an audio filter that is applied to the original audio, and since the original recording exists and is left untouched by the process, it can be easily reversed.

While it is possible to enhance an entire clip, you cannot enhance just one section of a clip and leave the rest untouched. That is a more advanced edit than Voice Memos is capable of performing in its current form.

If you do share the enhanced version of the recording with another person, only the enhanced version will be provided, not the original file. This does mean that you will be able to still remove the enhancement, but the recipient of the shared file cannot.

Folders and Favorites

Given the potentially large number of recordings that can be created by a regular Voice Memos user, especially if they use their mobile devices for recordings, steps have to be taken to organize the memos being stored. Apple has included a few ways to do this in the macOS version of the app.

The first way to do that is by setting a recording as a favorite, which can be done by clicking the heart arrow in the top-right corner of the app, making the icon opaque. You can click the icon again to stop marking a recording as a favorite.

The second organization element is folders found in the sidebar, which can be brought up and hidden by clicking the sidebar icon.

There are two types of folders available to use, with standard folders accompanied by Smart Folders. While the former are fairly normal containers for collections of recordings, Smart Folders are an automatically-grouped collection of files from all other folders.

Four Smart Folders are available to use, and are automatically populated, covering recordings listed as Favorites, All Recordings, Apple Watch recordings, and Recently Deleted recordings. These Smart Folders appear when needed, such as if it detects an Apple Watch Voice Memo has been synchronized with iCloud.

How to create a folder in Voice Memos in macOS Big Sur

• Click the new folder icon, at the bottom of the sidebar.
• In the text box, enter the name of the folder you want to create.
• Click Save.
• The new folder will appear under My Folders, underneath the Smart Folders collection.

Folders operate as you would expect, with users able to drag and drop recordings from one into another. Right-clicking the folder also brings up options to rename the folder, and to delete the folder.

Changing the contents of folders will not affect the listings of the Smart Folders, as the latter is compiled from all available Voice Memo recordings, regardless of source folder.

Some built-in iPhone apps do such a good job there’s no need to look for third-party alternatives. While you might not give it much attention, Voice Memos is one of those apps, and it gets even better every few years. If you’re looking for a voice recorder that backs up your content and syncs between your devices, Voice Memos is it.

But while the app is simple to use (you just open the app and press the big red Record button), there are hidden features you shouldn’t ignore, and minor annoyances you should fix.

Replace location-based naming with something that makes sense

Voice Memos labels its recordings not based on the date or time, but based on your location when you recorded it. It’s weird, and often not very useful. Instead of using the default naming — which is almost guaranteed to get lost once you add more recordings — start by renaming your audio files once you’re finished recording.

Select your recording and tap the title text. Hit the Delete key, enter a new name for your recording, and press Return. Or, even better, you can disable the location-based naming altogether. Just go to Settings > Voice Memos > Location-Based Naming.

Record voice notes faster by using Control Centre

You can use the Voice Memos shortcut in Control Centre to quickly start a recording — you just have to add it first. To set up the Control Centre option, go to Settings > Control Centre and add Voice Memos to the list. Now, swipe down from the top-right corner and tap the Voice Memos control to quickly open the app. To start a new recording, tap and hold the Voice Memos control and choose New Recording.

Edit your voice note or delete parts of the recording

Voice Memos doesn’t have a fully-featured audio editing suite (for that, you’ll need to use GarageBand), but you can quickly trim the audio or delete parts of the recording.

Select the voice note, tap the three-dotted Menu button, and choose Edit Recording. Then tap the Edit icon in the top-right corner and use the yellow handlebars to select the audio. If you want to remove what you have highlighted, tap Delete; if you want to only keep the selected part as the audio, choose Trim. Once you’re done, tap Save, and Replace if you want to save over your original file.

Enable automatic enhancement for your Voice Memos recordings

Sometimes your recording will have wind or other noise in the background, or the speaker’s audio just sucks. Starting in iOS 14, Apple introduced a new feature called Enhance Recording that uses machine learning to automatically enhance the audio quality. It will reduce background noise and it will punch up the speaker’s voice. Just select a recording from the list and tap Options. Then, enable the “Enhance Recording” option.

Enable “Skip Silence” to automatically cut long pauses

Introduced in iOS 15, the Skip Silence feature automatically snips out long pauses and awkward silences from a voice recording, meaning you’ll end up with much cleaner-sounding audio. Again, choose the recording, tap Options, and enable the “Skip Silence” feature. While you’re here, you can also increase the speed of the audio, if you think the speaker is a bit too slow.

Record in higher quality using Lossless Audio

If you want the best audio quality possible, you can use the Lossless Audio format instead of the default compression. Go to Settings > Voice Memos > Audio Quality. Here, switch to the “Lossless” option.

Choose when deleted voice notes are actually deleted

Like many other Apple apps (Photos, Notes), deleting a voice note in Voice Memos doesn’t instantly delete it. Instead, it’s only archived in a different folder that can be retrieved later. By default, this duration is set to 30 days, but you can change it based on your needs. You can choose to delete the files immediately, or never, if you want. Go to Settings > Voice Memos > Clear Deleted and make your pick.

Recover deleted voice notes

Like we mentioned above, deleted voice notes still hang around for 30 days. If you’re still in that window, it’s easy to recover a voice note: Open the Voice Memos app and hit the Back button in the top-left, then go to the Recently Deleted folder, tap on a recording, and choose Recover. Confirm using the Recover Recording button to place the recording back in the All Recordings folder.

If you want to permanently delete a recording, choose the “Delete” option and tap Delete Forever.

Organise recordings in multiple folders

If you’re going to use Voice Memos to record lectures, you might find its organisation to be a mess. Thankfully, there’s a way to organise all your voice notes into folders.

Open the Voice Memos app and tap the Back button from the top-left. Here, tap the New Folder button in the bottom-right and give the folder a name before hitting Save.

Now, go to the “All Recordings” folder and tap Edit. Select all the recordings that you want to move, go to Share > Move to Folder, and choose the folder you created above. Alternatively, you can move one recording at a time using the omnipresent drag-and-drop method.

Export your voice notes

Voice Memos are backed up and synced across all your devices using iCloud, but what if you want to share the voice note with a friend or back it up using a different cloud storage service?

You can easily export your notes in M4A format. You can convert the file to MP3 using a free online service like Cloudconvert.

To export a single recording, tap on it, and then choose the three-dotted menu. Here, tap Share and choose any app or conversation where you want to share the file. To share multiple files, tap Edit and choose the voice notes that you want to share. Then tap Share button to see all your sharing options.

If you don’t have access to a DAW with noise-reduction plugins there is also standalone software designed specifically for this purpose. Audio Cleaning Lab by Magix is a popular one.

Another option is to use a low-pass filter to roll off the very high frequencies where this noise is usually found. However, it’s usually difficult to completely remove the white noise without giving the audio a dull muffled sound.

The bad news is that you can’t remove white noise from a recording completely. White noise by definition lives all across the frequency spectrum, and can’t be distinguished from signal where they both exist.

The good news is that you don’t have to. For the most part your brain can’t hear noise when it is masked by a real signal in the same frequency range. So the noise reduction approach has two parts:

where there is no audio signal (“white space” or silences in the recording) just turn the gain down and you remove noise completely. This is “noise gating” and can be done by common plugins.

where there is signal, use spectral analysis to find out where in the frequency spectrum your desirable signal is, the use equalization to turn the gain down in parts of spectrum where there is nothing but noise. This is one of the main things “denoising” plugins do.

if you can identify non-white noise elements (hum, pops/clicks) use surgical dynamics and EQ to remove them.

That’s the basic forensic audio workflow. It’s a hard problem; good luck!

Audacity has a decent noise removal plugin. It’s free!

There are plugins that can do this. As far as I know, the RX Denoiser from iZotope is doing a fabulous job. See

Adobe Audition has great noise removal. Unfortunately I don’t know the specifics, but basically you select an area in which there is only white noise, it analyzes it, and removes that ‘type’ of sound everywhere else it occurs.

You might be able to use an MP3 encoder for this. Experiment with encoding to MP3s at lower bit rates than you normally would, and it should remove much of the noise while keeping the signal, in a psychoacoustically good way. It will degrade the quality of the recording, but it might be acceptable in a mix with other things.

If you are dealing with the white noise created during video production there are several steps to consider. Firstly, the power adapter will bring noise to the project. I recommend using the Camcorder batteries, which add almost no extra noise. The high end Panasonic video cameras have built-in noise reduction filters, which also reduce the noise.

Is this a presentation? Why record the sound in stereo when there is only one voice? This will add echo, which will cause production problems. It is normal to record in mono – it’s how the music industry record your music collection. I use a mic that I bought on ebay, from a company in Manchester (UK), for £14. Using It produces a mono recording on both tracks. In Final Cut Pro (Studio 3) the Audio Mixer from the Tools drop down menu has a stereo slider allowing the user to manipulate where the sound exists within the stereo spectrum.

If you’re adding music in stereo – that you have recorded the voice in mono – will not show. But the improved sound quality will make your production sound far superior. The Apple EQ in FCP appears a little complicated. But have a play, as it thins the sound making it less muffled. Only the bottom few categories on the EQ filter are the actual EQ; the rest are just filter settings, such as Gain. I’m looking at this now!

There is one other diamond for both video and music production when you are trying to get by on a budget: Soundtrack Pro. With your video project selected on the FCP Audio track right click the mouse to bring up the sub menu. Select ‘Send To’ and the listed Soundtrack link for the Aiff audio project. A small menu will ask you to save the file to your folder. Just click on OK. Now your sound is in Soundtrack Pro.

Highlight the entire sound clip using either ‘Select All’ or left click the mouse in the top right-hand corner of the sound and drag it to cover everything. There are some folder options in the menu on the left. Select the Analyse folder. Now tick all of the box options on the left for noise pops, etc. Select ‘Analyse’. The software will detect and audio problems and correct them, but you still may have a little white noise. This is where it gets clever. Select the entire sound again and set the Ambient Noise Point. This can be found in the Process drop down menu. Having set the noise point go back in and select ‘Replace with Ambient Noise.’ Ambient noise is a natural part of the sound spectrum. It’s often in most audio mixes, but we don’t notice. It’s like giving the noise camouflage.

At this point you may be happy with the sound, as the only other matter to consider is the level on final cut pro. This also can reduce the white noise. If you are still unhappy there is one other EQ diamond on Soundtrack Pro: The Parametric EQ, which is found in the Effects/Single Band EQ. I suggest that you place all three of the sliders to the left and adjust the top slider until the sound is as required. The other two sliders will control sound spectrum differences reducing the noise to near zero without losing too much quality.

When you have finished adjusting the sound use the save option from the drop-down menu. It will ask you how you want to save the file. It’s the top answer – just click on OK. This will automatically save the changes to the existing FCP sound file. You can continue with your video now. Warning: Always use slugs for gaps in audio and video. If you fail to do this your video will stutter when you add it to social media.

Add: Forgot to mention the noise reduction in Soundtrack Pro. Set the noise point then just click on OK for the noise reduction. Have a little listen to make sure that it hasn’t added a nasty digital sound to your work. If it has move two steps backwards and avoid. Sometimes it works quite well, but it’s dangerous!

Apple has released an enhancement to improve audio quality for Voice Memos on iPhone. No more searching for an audio recording app to enhance sound quality! I use Voice Memos frequently when doing interviews or taking notes for projects I’m working on, so I’ve been looking forward to this new iOS 14 Enhance Recording feature for some time. Anyone who records audio will find relief in the clearer sound and reduced background noise for new Voice Memos and previously recorded memos. Here’s how to use this simple, one-touch feature.

How to Enhance Voice Memos on the iPhone

This new audio improvement feature is tucked away in the Apple Voice Memos app, so it isn’t something you’re likely to stumble upon by mistake unless you regularly edit your recordings in Voice Memos. For more tips about the great new features Apple included in its iOS 14 update, subscribe to our free Tip of the Day newsletter!

Here’s how to find and use the Enhance Recording feature to improve sound quality on your Voice Memos:

1. Open the Voice Memos app.
2. Either record a new memo and then tap on it when you’ve finished recording, or select an existing recording. When you tap on it, the recording field will expand to give more options.

macOS Big Sur has been out for about a month now, but macOS releases never get quite as much attention as iOS releases, so there may still be some features that you’re not aware of. In our latest YouTube video, we rounded up some useful but lesser known macOS Big Sur tips that are worth checking out.

• AirPods Auto Switching – With macOS Big Sur and iOS/iPadOS 14, your AirPods will swap automatically to the device that you’re using at the current time, with no need to manually change the device you’re using them with. AirPods will work with iPhone, iPad, or Mac you’re actively using and listening to audio on. It mostly works, but this feature seems to sometimes be buggy.
• Drag and Drop Menu Bar Icons – If you open up the Control Center, you can click and drag on any of the options to add it to the menu bar. So if you want Do Not Disturb to have a one-click menu bar toggle, just drag it to the menu bar from Control Center. This works for Now Playing, AirDrop, DND, and more.
• Enhanced Voice Memos – When you use Voice Memos in Big Sur, there’s a new option to automatically reduce background noise and echo with a single click, useful when you’re recording lectures or meetings. You can also use Smart Folders for improved organization.
• 4K YouTube Videos – YouTube videos can be watched in 4K HDR in macOS Big Sur because the OS supports YouTube’s VP9 codec. Note that 4K YouTube options are going to be limited to newer Macs by default, but there’s a trick to enable them on older Macs. Enable the Develop menu in Safari settings, select Experimental Features, and make sure both VP9 Decoder and VP9 SW Decoder on Battery are enabled.
• Resize Widgets – macOS Big Sur has a new widget interface, and if you right click on any widget that has sizing options, you can choose a new size.
• Silent Notifications – On any incoming notification in the Today center, if you right click you can select “Deliver Quietly.” This setting will prevent future notifications from that app from popping up on your screen, but you’ll see them in the notifications list.
• Message Effects – Messages in Big Sur is a lot more like the Messages app on iOS devices. You can use Message Effects to enhance messages, find GIFs and insert photos. Just click on the little “A” on the left of the text bar to see a dropdown list of the options.
• Disable Tinting – Want a Dark Mode that’s even darker or a Light Mode that’s brighter? That’s possible if you turn off window tinting. Open up System Preferences, choose General, and uncheck “allow wallpaper tinting in windows.” With this disabled, windows won’t be affected by the wallpaper that you’re using.

For more on macOS Big Sur, we have a detailed roundup with all of the features, plus a features guide highlighting what’s most important, and a guide that has 50 must-know features.

There’s nothing more frustrating than setting a microphone up for an event or recording session only to find out that there’s some strange white noise crackling through the speakers. There a handful of reasons that a microphone will emit static sounds. The most common problem is that the gain, which is basically the mic’s sensitivity, is set too high on your amp or audio interface. However, ambient sound, bad cable connections, and moving air are also common culprits. Removing static is fairly easy so long as your equipment isn’t faulty and you can always edit static out after you finish recording if you’re on a tight schedule.

Online meetings can be time-saving and efficient. You can improve its experience by removing background noise, in case you are using Zoom.

Attending meetings or classes on your phone or laptop is very normal in today’s era. Online meetings have opened the door to get involved in any meeting on the go, but attending the meetings online does come with the cost of background noise. Dogs barking in the street, children playing in the lobby, can be very irritating and inappropriate at times. We have found 4 amazing ways by which you can remove background noise from your end in Zoom Video calls. Check the top ways to remove background noise in Zoom video calls:

Table of Contents

Use rooms with furniture carpets and other sound-absorbing materials:

Have you ever noticed that in an empty room how your sound echoes? Yes, each and every room produces some amount of echo, we might not be able to hear it, but there is some amount of echo in any room. The echo can be reduced if you have a heavy curtain or furniture inside it.

So, you should always try to do meetings in that room of your house which has most of the furniture, carpets and other sound damping materials. The microphones on devices are sensitive and can pick up even the slightest of sound. So, next time whenever you sit for an online meeting, make sure you try this method and see the results.

Use the Microphone correctly:

Most of the people don’t know where the microphone of their device is placed, so either they end up blocking the mic on their phone or they stay too far from the mic of their laptop. Blocking the mic makes your sound muffle and noisy. The mics on the phones are generally placed at the bottom of the phone and on the top bezel in the case of laptops. So make sure that they are neither blocked nor you are too far from them.

Additionally, you can also use an external mic if it is available with you, or you can just use any normal pair of earphones. External mic/earphones generally are better than onboard mics on most of the laptops.

Use inbuilt noise reduction tools:

Zoom is a really popular web conferencing tool that is used across the globe. It has many features and one of them is its built-in noise suppression tool.

It reduces the amount of background noise from your end and offers clean and crisp audio.

The only requirement in this is that you should have the latest version of the Zoom desktop app (5.2.0 or newer).

If you have the latest version then follow these steps:

1. Click on the Settings icon on the top right corner.
2. Then, select the audio option.
3. Under the suppress background noise menu, you will find 3 stages of audio separation select any one according to your surroundings.

Although it does make your voice a bit robotic. But, it eliminates almost all the irritating background clank from your video.

Use windows noise suppression tool:

Another way to reduce background noise in Zoom Video calls is this one. Windows also has its own in-built noise suppression tools if you are on Windows 7 or later, then you can also find it in your system. Just follow the steps below to enable noise reduction:

1. Open hardware and sound option in the control panel.
2. Under the sound option, click the manage audio devices.
3. Switch to the recording tab.
4. Select the microphone being used and click on properties.
5. You will find a slider that controls the microphone’s sensitivity, reduce it and see if it reduces the noise.
6. Also, go to the microphone effects option and enable noise reduction and enable acoustic echo cancellation.

This is a very effective way to remove the noise that you are getting in your video calls.

So these were Top 4 ways to remove background noise in Zoom video calls. Try out all the methods and it should get the job done.

Clear audio is an important part of conducting a successful stream or broadcast. There are a large number of apps with different features that are used for streaming, but it is important to make sure that the sound you provide comes with minimal background noise. One such application is OBS Studio, which provides several built-in tools that help reduce background noise while keeping your voice audible.

Without further ado, let’s see how you can easily remove background noise in OBS Studio.

How to remove background noise in OBS?

If you want to modify the sound in the OBS, then you must use filters. Fortunately, the app has a couple of filters just for noise reduction.

To add a filter, click on the Settings gear in the Audio Mixer section and from there, select Filters option.

The Filters window will open. Click on the Plus sign to add a filter. OBS provides 8 filters you can choose from. 2 of them, “Noise Gate” and “Noise Suppression” are for noise cancelling purposes.

First, you can add Noise Suppression filter, which helps to reduce background noise. The default value is set to -30dB and that’s the best to start with. Try to record a short sample to understand whether this value is enough for you to get rid of background noise. If not, play with the suppression level. Increase the dB level if you still a lot of background noise, and decrease it if the applied suppression level is too high and it cuts your voice together with the noise.

Another filter you can use to remove background noise in OBS is Noise Gate. This filter is a bit different than the previous one. It acts like real gates and doesn’t let any signal to pass if the volume of a signal drops below a certain threshold level. The threshold determines which sounds get in and which don’t.

You can use Noise Gate separately or in a pair with Noise Suppression. This mainly depends on the level of the background noise in your surroundings. If you’ve tried different suppression levels but it didn’t help very much, then you can also add Noise Gate. Start with the default settings and slide them up or down depending on your case.

Each case is different, so you should dedicate some time beforehand play with filter settings to find the best levels that go well with your audio devices and the surrounding environment.

Easy Way to Remove Background Noise in OBS

If digging into the settings and setting up filters sounds can sound like a hassle. So if it’s not for you and you are looking for a quick solution, then try Krisp.

Krisp is a noise cancelling app which works with a number of communication and recording apps, including OBS. It uses the power of AI to recognize unwanted noises and remove them from your recording or stream in a real-time.

It takes only a few steps to install Krisp and set it up. Once you’ve done it, you don’t have to worry anymore – Krisp will take care of all noises and help you have a successful stream with clear sound.

How to set up Krisp with OBS?

2. Follow the instructions of the Wizard to install Krisp

3. Afterwards, go to Settings in OBS and select Audio tab.

4. From there, chance Mic/Auxiliary Audio to Krisp Microphone (Krisp).

5. You’re done! Now start recording or streaming with OBS and let Krisp perform its noise cancelling magic.

Try using Krisp noise cancelling app together with OBS Studio for your next recording or streaming session and have noiseless experience without filters and expensive mics.

Because of the tremendous interest in audio recording on smartphones, I decided to do a little testing of my own. I tested the onboard mics, plus two external mics (a lavalier and a shotgun) connected through the headset (TRRS) port, and compared the results to those obtained with a dedicated recorder, my Sony PCM-M10 (see “My decisions in choosing a sound recorder”). For smartphones, I used my Galaxy S3 (Android Jelly Bean) and a friend’s iPhone 5 (with iOS 7). I also compared a friends iPad mini (iOS 6) to the Sony recorder. I used a KVConnection TRRS adapter for powered condenser mics, as both my lavalier (Pearstone OLM-10 omni) and shotgun (Audio Technica AT897) were battery-powered mics.

Samsung Galaxy S3

This was the US-Verizon version of the phone, using the Smart Voice Recorder and RecForge Pro apps. For recording, the phone was set to airplane mode and the noise reduction feature for calling was turned off.

I discovered right away that Samsung has modified the ability of the microphones to record sound. All recordings made through the TRRS port show the results of a noise gate and low-cut filter. What this means is that background noises (if they are not too loud) and low frequency noises are cut from the recordings. Close, loud sounds, like a voice spoken or sung into a microphone are recorded, but everything else is silenced. This only occurs when an external mic is attached, not with the onboard mics. The effects of the noise gate varied by mic; the lavalier sounded fine, but the shotgun sounded warbled, as the mic didn’t ramp up fast enough, sometimes missing the start of the speech. Using the onboard mics didn’t have a noise gate, but the quality was only so-so. Reviewing videos of external mics, like the iRig MicCast, the noise gate was obvious. If you are trying to record close dialog and want to exclude background noise, this is a good feature. If you want to record ambient sounds, this is horrible. Some of the fancier recording apps allow you to apply a noise gate; I wish Samsung had left that option with the user, rather than taking it away from us. There are many reports of poor audio quality when recording video with the Samsung Galaxy S3, which may have something to do with the noise reduction features.

The following video of the iRig Mic Cast shows how a noise gate works. In this case, the Mic Cast is supplying its own noise gate on top of the Galaxy S3 noise gate to reduce background noise.

I previously tested the SmartTech.com MUYHSMFF 3.5 headset splitter adapter and the Rockit headset splitter adapter on the Samsung S3. I first thought the noise gate was a problem of incompatibility with the connectors and returned them. The SmartTech adapter worked the same as the adapter from KVConnections. The Rockit headset splitter was even worse; it appears to be an adapter for a different set of microphones.

iPhone 5

This was an iPhone 5 running iOS 7.1, using the Voice Memos app. I used the same microphones as above, plus the onboard mics of the phone. The phone was set to airplane mode before testing.

The iPhone had none of the modifications of the Samsung phone, and did a reasonable recording job with onboard mics, and the lav and shotgun mics. The lack of preamps was obvious though, resulting in a lower recording level compared to the Sony PCM-M10. When the recordings were normalized to the same level, the recordings from the iPhone was noticeably noisier than the dedicated recorder. But overall, the quality was quite acceptable, especially for vocal work. The sound from the onboard mics was quite impressive, although mono, and not as good as the dedicated recorder. Using a relatively inexpensive shotgun, like the AT897, greatly increased the reach of the recording. A higher quality (less noisy) mic might add some very good sound to videos.

Waveform display showing the differences in sound recorded on the Samsung Galaxy S3, left, with the iPhone 5, both connected to a lavalier mic. Note the iPhone was picking up a little background noise and lower voice levels. The Samsung only recorded high voice levels. Both were independently normalized to –6 dB.

iPad Mini

This was an iPad Mini that had not been upgraded to iOS 7 yet. I used the AT897 shotgun plus the onboard mics for comparison. We used the Recorder Plus app.

The recording on the iPad was similar to the iPhone except that a low-cut filter was obvious. As with the iPhone, the recordings were a little noisier than the dedicated recorder, but would be good for vocals and louder sounds, but not for distant, quiet sounds. The sound from the onboard mics was quite good, but pulled in a lot of ambient sounds.

Synopsis

Although this was just a test of the headset port on a couple of smartphones and an iPad, the results were surprising, at least to me. I expected better performance from the Samsung, and was startled at how good the iOS devices sounded. The headset port is an analog port; better quality sound can probably be obtained from the charging ports using either dedicated mics (for iOS) or USB mics (for either iOS or Android). Either of these options would be suitable for note-taking, vocal and instrumental work, but smartphones have a way to go before they replace dedicated recorders for nature recording. Sound levels could be increased by adding a preamp or USB audio interface. However, if you are looking to set up a home studio, it is quite feasible to connect your studio mics and preamps to a tablet as your DAW. iOS devices are light years ahead of Android when it comes to sound recording. The software and hardware are more mature. Currently Android devices are limited by hardware inconsistencies and lack of suitable apps for anything but the most basic recording.

I think the noise gate really limits the usefulness of the Samsung galaxy phones as recording devices. I do not know if the Note or Galaxy Tabs also have this noise gate. Other smartphones, like the HTC One and several recent Nokia Lumias are reported to be decent audio recorders.

Update May 2022: Obviously this is a very dated post, and phones and apps are much better at recording sounds now, and their are a variety of mics made just for phones. However, I’m going to leave this post up so you know what to listen for, if you do decide to use your phone as a recorder.

How can you block out unwanted noise from meetings and calls when working at home? A solution like Krisp will block out unnecessary noise so that you can eliminate background noise from video calls and meetings.

Table of contents

Do you have constant noise in or near your home office that prevents your calls, meetings and interviews from being quiet? Do you have a dog that barks during your Zoom meetings? A toddler that happens to pop in when you’re on a call?

There’s a simple answer: use Krisp.ai! Krisp will block out unnecessary noise from the background on your video and audio calls. It works in Mac and Windows. Krisp is perfect for you if you take a lot of calls, but you are struggling with being able to find a quiet place to take your calls.

In fact, Becca started using Krisp recently because her computer fan was making a lot of noise and people on the other end of her calls informed her that she was hard to hear.

Note: we receive a small commission if you sign up for Krisp using our link. The commission won’t cost you anything, and will help support us in writing awesome remote work content in the future!

Now that we’ve covered the basics, we want to talk a little bit about how we use Krisp and how it might work for you.

Let’s get started.

What is Krisp.ai?

Krisp is a service that can remove background noises from the most common communication apps. That’s the simplest way to explain Krisp. Krisp aims to make your call sound clear so that there’s no distraction from your voice and what you’re saying.

What apps can Krisp block background noise from?

Krisp will work with Zoom, Google Hangouts, Skype, Microsoft Teams, Slack and many more apps. There are actually over 800 communication tools that support Krisp. Krisp will likely work with any way that you are communicating with anyone outside your home office!

While it seems second-nature to use all these apps to chat with coworkers, friends and family, it’s more difficult to keep in mind how you sound, and whether distractions in the background are impeding the quality of your call.

For professionals who work from home and often lead presentations, team meetings, client meetings or other types of voice-heavy online events, having background noise can certainly be a type of impediment on the quality of the virtual event overall. It pays to look into ways to sound as best as possible and keep your audience’s attention on what matters.

When do I need to use Krisp?

Krisp is great to use if you have an interview, but are not home, or if your home isn’t quiet at the moment.

For example, throughout our professional careers, both Becca and I have taken calls from a lot of different locations. Maybe we took some calls from home, but we lived on busy streets. Maybe we took calls in busy cafes with a lot of noise. Maybe we took calls in a loud coworking space.

What ever the case, we made it hard for people on the other end to hear what we were saying.

Krisp works great to help silence your background noise. Krisp can also work to help cut out the noise on the other end of the call as well. Krisp works both ways!

Being on the other end of a lot of calls, I’ve heard a lot of things, like dogs barking, voices, laughter or crying from small children, street noises like traffic, police sirens, music and everything else that you can imagine. I wish that everyone would use something like Krisp (or find a quiet place!) so that our calls and meetings could be effective.

Krisp will be the perfect solution to ensure that the audio on the call is as clear as possible, while you’re working from home.

How much does Krisp cost?

Krisp has a few different options. The easiest way to get started is to try it, for free ($0.00). The free option has a time limit of 120 minutes per week where you can mute your background noise. You get an additional 120 minutes per week where you can block out noise coming from your speakers.

The upgraded Pro plan is $5/mo (billed yearly) or $12/mo if you want to only try it for a few months or don’t want to commit to a full year yet.

If you’re part of a company, or someone who makes the IT decisions, Krisp is available for teams! It’s still $5/mo/user. The teams plan allows you to manage members and there is upgraded support.

If you’re a team or an enterprise user, you can contact the Krisp team to get a price.

How can I try Krisp for free?

Visit Krisp.ai and download the app for your computer. Try out the free trial. It’s simple.

How to use Krisp for eliminating background noise during work calls

The set-up onboarding process is fairly straightforward. Once you download Krisp, it will prompt you to sign in or create a new account. Once that is done and squared away, you can open the app.

You’ll see an onboarding screen that looks something like this:

From here, you can choose a program to see a video walk-through and instructions on how to set it up.

Generally, what you are doing here is using Krisp as a virtual microphone and speaker. Krisp will handle all of the noise cancellations when you have selected to use these audio methods.

Krisp will also be able to exclude other voices (people who are not you) from your calls. This is a game changer if you are in a public place or taking calls from a cafe.

If you are in a big open room that has a lot of echo, Krisp also has you covered. Their software will help eliminate echo from your calls to help isolate your voice.

Can Krisp remove the background from your videos?

Yes! Krisp can now assist you in removing the background from your video. If you have a distracting or background that you want to spruce up, Krisp can help! You can use their high quality photos as your backgrounds or select from your own library.

For M1 Mac users, Krisp will support virtual backgrounds! You can learn more about this features on their announcements page.

The real benefit is being able to control one background on several different video platforms. You can select your virtual background and it applies to Zoom, Google Meet, Skype, Slack, etc…

Feel free to download some of our photos for your virtual backgrounds!

Should you try Krisp.ai to block out background noise when taking video calls?

Sure! Go for it. There’s really nothing to lose when you try their free trial. It’s free, so it costs you absolutely nothing, and you can experiment with how this unique solution could change the video call and meeting experience when you work from home with noisy distractions. Let us know how it goes for you!

Introduction: How to Remove Background Noise From Video?

We often film video with our phone. They help us record the moment we want to memorize. But you will always come across this that when you view the videos, they have heavy background noise. Maybe it is minor or maybe it is destroying your video. How can we remove background noise from video? Is there any tool that can do this. The answer is definitely yes. I got a full guide for you to remove background noise from video based on its simplicity and functionality.

Step 1: Extract Audio File From the Video

As we are going to use audio editor to process the background, the very beginning thing we need to do is to rip the audio from video without any loss of quality. There are quite a lot of audio rippers in Google. The one I like most is Video Grabber. Like my previous thread mentioned, this online service can do many things. It can help to rotate videos shot in wrong direction, download videos and record videos and sound. Sorry, I get it too far. Back to this topic, Video Grabber can directly convert video to audio quickly and the sound quality will be kept maximally. Let’s check the steps.

1. Access the web service, click “Convert Video” > “Select files to Convert” to add the video to process.
2. Click option “Format” at the bottom and enable “MP3” which is the format the video will be converted to.
3. Click “Convert” on bottom right and the created audio sound track will be saved to your hard drive.

Step 2: Remove Background Noise in the Sound Track

This time we will use Audacity, a free and well-known open source audio editor to complete this task. It is also very easy to use when it comes to removing background noise.

1. Open Audacity, and load the audio file to process. You can listen to the entire audio and make sure the portion where you can hear the noise. Select that portion through a click or drag way.
2. Go to “Effect” tab on the top toolbar and choose “Noise Removal…” from the dropdown list.
3. You will find a box “Noise Removal” will pop up. I highly suggest you leave the settings default, then click on “Get Noise Profile” > “OK”. Audacity will magically remove most of the background noise from the audio file and export the soundtrack as a new MP3 file on your hard drive.
4. Replace the audio in the video with this fixed one.

Step 3: Replace the Audio in the Video With the Fixed One

After we get the corrected sound track, we can move on to the final step: replace the old audio file with new fixed one in the video. The free program we will use is Windows Live Movie Maker.

1. Open Movie Maker on your computer. It’s a pre-installed software on Windows. Drag and drop the video to the right panel.
2. Click “Edit” on the top right of the toolbar section, find “Video Volume” and move its to the left end to turn off the sound in the video.
3. Still under “Edit” tab, find the option “Add music”, drop it down to choose “Add music. ” and you can import the fixed audio file and place it from the start of the video.
4. Click “Play” button on the player to preview the video. If it is ok, click the “Menu” button and “Save movie” to save the video as an MP4 or WMV file in your computer.
