MP3 · WAV · AIFF · FLAC · free

MP3 to MIDI, on your own computer.

Online converters ask you to upload the file, often cap the length or the number of files, and send back a MIDI file to import by hand.

TONIQ converts MP3, WAV, AIFF and FLAC on your Mac or PC. Nothing is uploaded, there is no length limit, and the MIDI drags straight onto a track. Chords included.

MP3 to MIDI: questions.

Is there a free MP3 to MIDI converter that does not upload my file? +
Yes. TONIQ converts on your own Mac or PC as a standalone app or a plug-in. The audio never leaves your computer, and there is no length limit.
Can I convert WAV to MIDI as well? +
Yes: WAV, MP3, AIFF and FLAC. A WAV keeps more detail than a heavily compressed MP3, which can help on dense material.
Does it work on a full song MP3? +
Yes. Choose Full mix and TONIQ separates the parts first, then writes a MIDI track for each: drums, bass, chords and the vocal melody.
Do I need a DAW? +
No. The standalone app takes a file and gives you a MIDI file. In a DAW, the plug-in drags the MIDI straight onto a track.
Is it really free? +
The conversion is free for good, with no watermark. It asks for your email once and checks it with a code. Shaping the MIDI and editing notes inside the audio is TONIQ Pro, $129 once.
