Upload an audio file to transcribe it into MIDI notes
This audio to MIDI converter runs a polyphonic transcription model, powered by Spotify's open-source Basic Pitch, entirely inside your browser. When you upload a recording, the audio to MIDI converter analyzes the waveform frame by frame, estimates the pitch of every note it hears, and groups those pitches into discrete notes with start times, durations, and velocity. Because the model is polyphonic, the audio to MIDI converter can follow several notes at once, so chords and overlapping lines are captured rather than flattened. The resulting notes are written into a standard MIDI file with an estimated tempo, ready to drag into any DAW for editing, re-instrumentation, or printing as sheet music.

The audio to MIDI converter handles melodies, chords, and full takes, giving you note data you can shape in any DAW.

Unlike basic pitch trackers that follow a single line, this audio to MIDI converter detects multiple notes sounding together. It reads chords, harmonies, and two-handed piano parts, capturing each note with its own pitch, timing, and velocity for faithful transcription.
Captures several simultaneous notes, not just the top line
Note loudness is preserved for natural-sounding MIDI
Tune note thresholds to catch more or fewer notes

Pick Clean Melody, Chords, or Full Mix and the audio to MIDI converter adapts its thresholds to your material. A vocal take, a solo guitar, or a piano performance each get sensible defaults, and advanced sliders let you control minimum note length and pitch range.
Clean Melody mode tracks a single voice or lead
Optimized for guitar and keyboard harmony
Set minimum note length and pitch range

The audio to MIDI converter writes a standard .mid file with an estimated tempo, so notes line up sensibly when you drop it into your DAW. Optional pitch bends preserve slides and vibrato, and an optional grid snap quantizes notes for tighter editing.
Opens in Ableton, FL Studio, Logic, and more
Optional bends keep slides and vibrato
Optional quantize to an estimated beat grid
