WAV to MIDI Converter

WAV is the studio format — uncompressed, full quality, the kind of file you bounce out of a DAW or capture from an interface. That clean signal is exactly what an AI transcriber wants, which makes WAV to MIDI one of the most accurate conversions you can do.

Drop a WAV here and the notes are detected right in your browser. Nothing is uploaded, so your stems and session bounces never leave your machine.

Best-case accuracy

Because WAV is uncompressed, there are no codec artifacts to confuse the model — clean takes transcribe noticeably better than a low-bitrate MP3.

Great for stems

Bounce an isolated instrument or vocal stem to WAV, convert it, and get a tight MIDI part you can re-trigger with any sound.

Private by design

Session bounces and unreleased recordings stay on your device — there is no server in the loop.

WAV to MIDI — FAQ

Does WAV convert to MIDI more accurately than MP3?

Often yes. WAV is lossless, so the model sees a cleaner signal than a compressed MP3. The biggest factor is still how isolated and clear the part is.

Is there a file size limit for WAV?

There is no hard server limit because nothing is uploaded, but very long WAVs use more memory and take longer since all processing happens on your device.

What sample rate should my WAV be?

Any rate works — the tool resamples to the model’s 22.05 kHz internally. 44.1 kHz or 48 kHz files are perfectly fine.
