pianoify

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
