Apple introduced Enhancing Recording in the Voice Memos app with iOS 14 and iPad OS 14. So please 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 start the “Voice Notes” app. Use Apple’s built-in Spotlight search if you can’t find it on your iPhone’s home screen or in the app library.
Select the voice recording that you want to edit. Once opened, tap on the three dot menu icon on the left side of your screen.
Select the “Edit recording” button in the following menu.
At the top left, tap the magic wand-like icon.
Depending on the length of your recording, the voice memo app will automatically process the audio within seconds to a minute to reduce background noise and room reverberation. When that’s done, the button will be highlighted.
Play the recording to preview the changes. When you’re satisfied, tap Done to save the modified clip.
By default, the voice memo app overwrites the original audio file. To save the changes as a new separate clip, you can create a duplicate before applying the Enhance Recording filter.
To do this, open the audio clip and tap on the corresponding three-dot menu icon. This time, choose Duplicate instead of Edit Recording.
The app will instantly create a duplicate of the original audio file and add it to your list of recordings. It has the same title with a “copy” on the back. You can rename a file by tapping it once for options and then selecting its name to edit it.
Because enhancing recording relies on automated algorithms to distinguish noise and echo from audio, it does not always provide accurate results and can be a hit or miss.
In addition to using the advanced recording feature, you can record audio in a lossless format that takes up more storage space but produces better quality.
