Quick answer
TuneTrace normally saves recordings and clips as M4A. Play them directly from your local library, offline or with the screen locked. You do not need to convert them to MP3 first.
Step by step
3 stepsSave the recording to your library
Open the recording, check its clips and tap “Save to Library”. You can also keep a long interview as one track.
Select the tracks you want to keep and save them Play it directly in TuneTrace
Open the saved audio and listen to its beginning, middle and end. M4A works with playlists, playback speed and lock-screen listening.
Playback progress, volume, and the player menu Export when another app needs the file
With export access unlocked, use the track’s “Share/Export” menu. If another app requires MP3, use a separate audio converter. Renaming a file does not convert it.

Common questions
Can I change .m4a to .mp3 by renaming it?
No. Changing the extension does not change the audio encoding and may stop other apps recognizing the file.
Is M4A lower quality than MP3?
The extension alone does not determine quality. Both the source audio and encoding settings affect what you hear.
