A NOTE BEFORE YOU START

Made for melodies,
not miracles.

01 / THE INPUT

Keep it simple.

A clear, single-note melody works best. Try a solo instrument or a voice without backing music. The current detection range is approximately 65–1000 Hz.

02 / THE OUTPUT

A starting point.

MIDI notes are an approximation, not an exact transcription. Complex mixes and overlapping notes may produce poor results or fail.

03 / YOUR PRIVACY

Yours to keep.

Processing happens locally in your browser. Your audio is not uploaded, and there is no login or conversion history.

04 / HOW IT WORKS

Audio to MIDI.

Choose an MP3 or another supported audio file, select Convert, and download the MIDI. A WAV to MIDI converter uses the same local process. Your browser must support the file's encoding.
