Audio to MIDI conversion lets you turn any recording into editable MIDI notes. Vocuno uses Spotify’s Basic Pitch neural network to detect the pitch, timing, and velocity of every note in your audio — including chords and multi-instrument recordings — and outputs a standard .mid file you can open in any DAW.
Monophonic recordings (single melodies) give near-perfect transcription results. Polyphonic recordings — chords, complex mixes — are more challenging but still produce very usable MIDI output. For best accuracy, use isolated instrument tracks.

What’s included

AI-powered detection

A neural network based on Spotify’s Basic Pitch model accurately detects pitch, timing, and velocity from any audio recording.

Polyphonic support

Handles complex polyphonic audio — chords, melodies, and multi-instrument recordings are all transcribed.

Any audio format

Upload MP3, WAV, FLAC, AAC, OGG, or any other common audio format. No conversion needed before uploading.

Standard MIDI output

Download a standard .mid file compatible with Ableton Live, FL Studio, Logic Pro, GarageBand, Cubase, Pro Tools, and more.

Note-level precision

Get accurate note-on/off timing, velocity, and pitch — fine enough to use the MIDI directly in your productions.

Free & browser-based

No software to install. Upload your audio, get your MIDI file, and download — all in the browser at no cost.

Frequently asked questions

The AI uses a neural network based on Spotify’s Basic Pitch model to analyze the frequencies in your audio and detect individual musical notes. It identifies the pitch, timing, duration, and velocity of each note and writes them to a standard MIDI file.
Yes. The AI handles polyphonic audio and can detect multiple notes playing simultaneously — piano chords, guitar strumming, or multi-instrument recordings. Results are best with clean recordings and isolated tracks.
You can upload MP3, WAV, FLAC, AAC, OGG, and most other common audio formats. The AI processes any standard audio file.
Yes. The audio to MIDI conversion tool is free to use. Upload your audio and download the MIDI file at no cost, with no account required.
Yes. The output is a standard .mid file that works with any DAW — Ableton Live, FL Studio, Logic Pro, GarageBand, Cubase, Pro Tools, and more. Import the MIDI and assign any virtual instrument you like.
The AI achieves high accuracy on clean, well-recorded audio. Monophonic recordings (single melodies) give near-perfect results. Polyphonic recordings are more challenging but still produce very usable MIDI output. For best results, use isolated instrument tracks rather than full mixes.
