Audio to MIDI — workflow

Estimate pitches and durations from audio to create editable MIDI notes.

  1. Choose a short source with a clearly audible target instrument.
  2. Compare the source and detected notes after conversion.
  3. Fix false notes, octave errors, and durations, then save MIDI.

Before you start

It does not guarantee exact transcription of every instrument in a mix. MIDI does not preserve the source timbre.

Processing, free limits, and device support

Standard separation, noise removal, and BPM analysis run in your browser. HQ separation, music/loop generation, reference mastering, OCR, and cloud saving send inputs or audio to servers according to the feature you choose.

Standard separation, noise removal, and BPM analysis are free. Autotune and some other tools have free-use limits; HQ and generation features have plan or credit conditions. Check the price shown before running and the pricing page.

Desktop Chrome or Edge is recommended. Features depend on GPU, memory, and browser. Test a short file first, including on mobile devices.
