Hi Product Hunt — I built MP3 MIDI Tool for an audio-to-MIDI workflow that runs in the browser instead of sending the selected recording to an upload queue. The tool converts MP3 or WAV recordings to downloadable MIDI. A second path renders audio or MIDI as visible sheet music and provides MusicXML and SVG downloads for editing or reuse. It is free to use and does not ask for an account. I kept measured runs visible on the site: one comparison uses the same four-note phrase saved as WAV and MP3, while the sheet-music page records both a four-second smoke test and a 31-second browser run. The reusable MusicXML generator, CSV results, examples, and tests are also public on GitHub. I would value feedback on two things: how the note timing holds up on clean solo recordings, and whether the generated MusicXML is convenient to repair in the notation editor you already use.
