About PureMIDI
PureMIDI is a browser-based audio-to-MIDI converter and MIDI editor. Users upload a recording (MP3, WAV, M4A, FLAC, OGG, WEBM, AAC or AIFF), a video soundtrack, or a sheet-music score, and the service detects pitch, timing and velocity to produce a standard .mid file that can be opened in any DAW. A free account includes a preview (up to 30 seconds of audio, or the first page of a PDF score) before any credits are spent.
Best for
- Turning a hummed or played melody, a recorded riff or a PDF score into editable MIDI for a DAW or notation program
- Transcribing a melody idea: A producer records a vocal or instrument line and converts it into MIDI to re-voice it with a software instrument.
- Learning a song: A student converts a recording into MIDI and notation to study the notes and rhythm.
- Digitizing a printed score: An arranger uploads a PDF score, checks the re-engraved draft and exports MusicXML to MuseScore, Sibelius or Dorico.
- Remixing and sampling workflows: A producer extracts a riff or bass line from audio they are authorized to use and edits it in a DAW.
Not ideal for
- Users who need a documented API, fully automatic transcription of dense full mixes without manual cleanup, or a refundable subscription
