QAudioEditor

QAudioEditor is a lossless audio editor for iPhone and iPad. Open an MP3, AAC (.aac), M4A (.m4a), Apple Lossless, FLAC, or WAV file, see its waveform, and cut, crop, fade, normalise, 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 FEATURES - Frame-accurate cut, crop, and trim - Lossless fades and one-tap normalize - 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 - File details, unlimited undo, and crash-safe session restore - 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.
