PtP Audio Player vs QAudioEditor

PtP Audio Player is a practice tool for musicians. Import audio files, create precise loop regions on the waveform, and control speed and pitch independently. WAVEFORM LOOPING Draw loop regions with a tap and drag. Up to 6 named, color-coded loops per file (A–F) so you can mark verse, chorus, solo, and bridge all at once. Snap loops to beat transients for musically precise boundaries. SPEED & PITCH CONTROL Slow down to 0.5x without affecting pitch. Speed up to 2x for challenge runs. Shift pitch by semitones or fine-tune in cents — independently of tempo. See the detected key update in real time as you transpose. BPM DETECTION Automatic BPM detection on every imported file. Tap-to-snap aligns your loops to the beat grid with no manual work. TRIM & EXPORT Cut intros and outros, save a clean loop as a new file, and share directly from the app via AirDrop, Files, or any other app. PLAYLISTS Organize your practice set into playlists. Auto-advance moves to the next track with a configurable delay — perfect for lesson plans and setlists. FREE Up to 5 audio files 2 loops per file All import and playback features PRO — ONE-TIME PURCHASE Unlimited audio files 6 loops per file (A–F) Speed control, pitch shift & trim No ads Supports MP3, M4A, WAV, FLAC, AIFF.

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 - 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.
