pianoify — turn any recording into piano

Drop in a recording, hear it back as piano. Drop an audio file or paste a YouTube link. It is decoded in the tab, drawn as a waveform, and cropped to ten seconds. That clip goes to a transcriber, which sends back the notes — and the piano roll fills in while the model is still decoding, plays on a sampled Steinway grand with a working damper pedal, engraves the transcription as sheet music, and crossfades against the original recording. Audio to MIDI, free, in the browser Sheet music you can export as MusicXML Chords recognised under the notes Works on an MP3, a WAV, a voice memo, or a YouTube link Loading the app — it needs JavaScript and the Web Audio API.
