QAudioEditor
Lossless MP3, AAC, M4A editor
Free · In-App Purchases
QAudioEditor is a lossless audio editor for iPhone and iPad. Open an MP3, AAC (.aac), M4A (.m4a), Apple Lossless, FLAC, or WAV file - or a video (MP4, MOV, M4V) to edit just its audio - see its waveform, and cut, crop, fade, normalize, copy/paste, or append audio - then save without re-encoding. Untouched audio is preserved byte-for-byte; only faded or normalized regions are adjusted, and always losslessly - MP3 and AAC by rewriting the codec's gain fields (the mp3gain/aacgain technique), and WAV, ALAC and FLAC in the sample domain - so there is no generation loss.
SUPPORTED FORMATS
- MP3 (MPEG-1/2 Layer III, constant or variable bitrate)
- AAC - AAC-LC, HE-AAC and HE-AAC v2 - in ADTS (.aac)
- AAC in MP4 (.m4a)
- Apple Lossless / ALAC in M4A (.m4a)
- FLAC (.flac), 16- and 24-bit
- WAV / PCM (.wav), 8- to 32-bit and 32-bit float
- Video (.mp4, .mov, .m4v) - the audio track is extracted losslessly for editing
FEATURES
- Frame-accurate cut, crop, and trim
- Split markers - drop markers anywhere, drag them to fine-tune, and split a long recording into numbered files in one step
- Export Selection - save just the selected part as a new file
- Very large recordings - multi-gigabyte WAV and FLAC files open, edit and save smoothly; the audio is kept on disk instead of in memory
- Lossless fades and one-tap normalize
- Pull the audio out of a video (MP4, MOV, M4V) - open it, or insert it at the playhead; AAC and ALAC tracks are extracted with no re-encoding
- Cut, copy, paste, and insert or append other files of the same format (.aac and .m4a interchange freely)
- Hardware-keyboard shortcuts on iPad
- Playback follows the view - scroll to another part while playing and it plays from there
- Rich waveform with peak + RMS view, zoom that stays centered on the playhead, and an overview navigator
- Spectrogram view - see the frequency content over time on a log scale; toggle it with the waveform (cached for instant reopen)
- File details, unlimited undo, and crash-safe session restore
- Edit tags - title, artist, album and cover artwork - saved losslessly (MP3 and M4A/AAC)
- Export raw AAC as a seekable .m4a
- Universal purchase - buy once, use on iPhone, iPad and Mac
Free to edit and to save results up to 5 minutes long. QAudioEditor Pro (a one-time purchase) removes the length limit so you can save recordings of any length - and one purchase unlocks Pro on iPhone, iPad and Mac.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Work with very large recordings: WAV and FLAC files of several gigabytes now open, edit and save smoothly on iPhone, iPad and Mac - the audio is kept on disk instead of in memory.
Also in this update:
- Copying, pasting and inserting long passages uses almost no memory
- Edits that run to the end of a file now reach the very last moment of audio
