FAQ

Is this an MP3 to MIDI converter?
Yes. Paste or drop an MP3 and it returns a Standard MIDI file you can edit.
Can it convert WAV to MIDI too?
Yes — WAV, OGG, M4A, AAC and FLAC are all supported by this audio to MIDI tool.
Do I need to sign up?
No. There is no account, no upload and no batch — one file at a time, fully in your browser.
What does the MIDI file contain?
The detected melody as note events (pitch, timing and length). It is monophonic: best with one clear line, not a full mix.
Is there a limit?
One file per conversion. Very long recordings are capped at the first three minutes for speed.
