When you record audio on your device, there are several ways that unnecessary noise can creep into your clips. Fortunately, the pre-installed voice memos app on your iPhone or iPad can clear up background noise and echoes with a single tap. How to use it.
Apple introduced Enhancing Recording in the Voice Memos app with iOS 14 and iPad OS 14. Therefore, be sure to update your iPad or iPhone to the latest firmware version before proceeding. If you have uninstalled the voicemail app, you can download it again from the App Store.
Now launch the “Voice Memo” 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 want to edit. Once opened, tap the three-point menu icon on the left of the screen.
In the following menu, select the “Edit recording” button.
Tap the magic wand icon at the top left.
Depending on the length of the recording, the Voice Memo app processes the sound to automatically “reduce background noise and reverberation in the room within seconds to a minute.” When done, the button is highlighted.
Play the recording to preview the changes. If you are satisfied, press “Done” to save the modified clip.
By default, the Voice Memos app writes the original audio file. To save the changes as a new separate clip, you can create a duplicate before using the “Enhanced Recording” filter.
To do so, open the audio clip and then tap the corresponding three-point menu icon. This time, select the “Duplicate” option instead of “Edit recording.”
The app will instantly create and add a copy of the original audio file to your recording list. It will have the same title with a “copy” attached to the back. You can rename a file by tapping it once to view options and then selecting its name to edit it.
Since Enhanced Recording relies on automated algorithms to distinguish noise and echo from sound, it will not always give accurate results and may be a hit or miss.
In addition to using the Enhanced Recording feature, you can consider recording audio in a Lossless format, which takes up more storage space but provides higher quality.
