SoundToMIDI is a browser-based audio-to-MIDI converter for musicians, producers, songwriters, arrangers, music teachers, and students. It accepts MP3, WAV, FLAC, M4A, OGG, AAC, and compatible MP4 files, then analyzes the audio on the user’s own device. The source recording is not uploaded, and no account is required.
After transcription, users can inspect the detected notes in a piano-roll view, review note statistics, and compare playback of the original audio with the generated MIDI. A Raw MIDI file can be downloaded for free and opened in compatible DAWs or notation software for further editing.
Users who want a cleaner starting point can also preview a cleaned result before deciding whether to buy the cleaned MIDI download for a one-time $2.99 charge. Cleanup controls can focus on melody, bass, or piano. This optional purchase does not replace the free Raw MIDI workflow.
SoundToMIDI is designed to make a useful editable draft quickly, not to promise perfect transcription for every recording. Clear melodies and isolated instruments work best. Dense full mixes can introduce extra notes or errors and may still require manual editing. Typical uses include moving a voice memo into a DAW, studying an instrument line, preparing lesson material, and turning a musical idea into an editable MIDI sketch.
