Turn a recording into editable MIDI notes: melodies and chords via a neural pitch model, drum grooves via onset detection. All of it runs on your device.

Melodic mode transcribes pitched material - vocals, guitar, piano, synths, even chords. Drums mode detects kick, snare and hi-hat hits in a groove and maps them onto General MIDI pads.
Melodic transcription uses Spotify's open-source Basic Pitch neural network, downloaded once (~900 KB) and run by your browser. Nothing is sent to a server - the audio stays on your machine.
The detected notes appear on a piano-roll preview. Download the .mid file - with the detected tempo embedded so it lands on the grid - and drop it into any DAW, notation app or hardware workstation.
MIDI is the editable form of a musical idea. Once a melody exists as notes instead of audio, you can fix the timing, transpose it, change the sound from piano to strings, or build harmonies on top. This converter is the fastest way to get there: hum or play the idea, transcribe it here, and continue in your favorite editor.
Typical uses: turning a voice memo into a starting point for a song; lifting a bassline or lead from a demo so you can re-voice it; extracting the groove from a drum loop to drive your own samples; and transcription practice - seeing what a phrase actually is before you trust your ear.
Polyphonic transcription is genuinely hard, and no converter is perfect on dense mixes. You will get the best results from a single instrument or voice, reasonably clean, without heavy reverb. For a full song, consider isolating a stem first - a vocal or bass stem transcribes far better than the whole mix.
Yes. Melodic mode uses Basic Pitch, a polyphonic model, so piano chords and guitar voicings come through as multiple simultaneous notes. Accuracy is highest on clean recordings of a single instrument.
Drum hits are noise transients without a fundamental pitch, so a pitch model cannot represent them. Drums mode instead detects onsets in low, mid and high frequency bands and classifies them as kick, snare or hi-hat on standard General MIDI drum notes.
No. The neural network itself is downloaded to your browser (about 900 KB, once) and the inference runs locally. Your audio never leaves your device.
Yes - that is exactly what MIDI is for. Download the .mid file and edit it in any piano roll. Ghost notes and octave errors are normal on reverb-heavy or noisy sources; cleaner input gives cleaner output.
The tool also estimates the BPM of your audio and embeds it in the file when the estimate is confident, so the notes line up with the bars in your DAW. Otherwise it defaults to 120 BPM with timing preserved in seconds.
