Hear Why a Focused Source Makes Better MIDI
MIDI stores notes rather than sound, so it can't be previewed like an MP3. These audio examples show what the converter actually hears: isolating vocals, piano or drums first gives it a far clearer part to follow than a dense full mix.

A Music Converter to MIDI That Understands the Source
A full song, a solo piano take, a vocal line and a drum performance don't carry the same information. TuneStems sends each one to a transcription model built for it.
What You Can Do with an Audio to MIDI Converter
Convert music to MIDI whenever you need editable notes and timing rather than another rendered audio file.
Convert Song to MIDI
Pull the melody out of a track, then change the instrument, key, tempo or arrangement in your DAW. The song to MIDI converter hands you the notes, not another copy of the recording.
Vocal to MIDI
Convert vocals to MIDI from a sung take, a humming reference or an isolated acapella, then use the notes to drive a synth or sketch a new arrangement.
Piano to MIDI
The piano to MIDI converter transcribes an acoustic or electric piano recording with note timing, velocity and sustain pedal data, ready for editing, study or notation.
Drums to MIDI
The drums to MIDI converter turns a performance into an editable drum MIDI pattern, so you can swap kits, reinforce the mix or tighten the groove. It reads drum audio to MIDI from a full mix or from a standalone drum WAV.
Instrument Transcription
Use the general audio to MIDI mode for guitar, bass, strings, winds and keyboards, or anything else with a clear pitch to follow.
Remixing and Production
Lift a musical idea straight out of an MP3 or WAV, then quantize, transpose and layer the MIDI without re-recording a single note.
