- It accepts MP3, WAV, OGG, FLAC, and M4A, with controls for note filtering, minimum length, and transposition.
Field notes
The workspace accepts several common audio formats and can also request microphone access for a fresh recording. Its editing controls expose a quiet-note threshold, minimum note duration, and semitone transposition before downloading a .mid file. The page specifically narrows its intended use to single melodic lines and warns that chords, drums, and full mixes may produce incomplete or incorrect results. It also notes that longer audio requires more time and device memory.
