Hi Product Hunters, I built SoundToMIDI to turn audio into editable MIDI without sending the source file to a server.
Drop in an MP3, WAV, FLAC, M4A, OGG, or compatible MP4. The transcription runs in your browser. You can inspect the piano roll, compare the original with Raw and Cleaned MIDI, and download the Raw MIDI for free. A one-time $2.99 option unlocks the cleaned download.
It works best on clear melodies or isolated instruments. Dense mixes still need cleanup, and I don't want to pretend otherwise.
I'd especially like feedback on note accuracy and whether the cleanup controls save time in your own workflow.
