What this converter does

The free Audio to MIDI Converter is a beta tool for user-owned audio. It sends the file to the official backend automatically, waits for transcription, then returns a MIDI file that can be downloaded or opened in MIDI Piano Trainer.

Best source audio

Clean solo piano works best. Short clips, low noise, clear attacks, and stable tempo are much easier to transcribe than full songs, vocals, drums, reverb-heavy recordings, or mixed instruments.

Quality expectations

Audio-to-MIDI quality depends on the recognition model, preprocessing, and the recording itself. The free backend can be slow, and beta results may miss notes, add extra notes, or estimate timing imperfectly.

How to use the converter

  1. Prepare a short audio file you own.
  2. Open the Audio-to-MIDI page.
  3. Upload MP3, WAV, OGG, FLAC, or M4A.
  4. Wait while the backend queues and processes the file.
  5. Download the MIDI or open it in MIDI Piano Trainer.

FAQ

Does it download YouTube?
No. Upload your own audio file. The project does not download YouTube directly.
Why can conversion take minutes?
Piano transcription is heavy, and the free backend may process jobs in a queue.
Will it be perfect?
No. It is a beta workflow and works best on clean solo piano.
