This tool converts an audio file to MIDI using the most cutting-edge artificial intelligence technology. Choose an audio file for solo piano (8 minutes or less) from your device to watch the magic happen! Tips: The less reverb the more accurate the result.

During the conversion process, your computer may become sluggish (mouse pointer may freeze). If the browser asks you to wait or terminate, please do wait... It takes approximately half the length of the original sound file for the AI to make this conversion. It's worth the wait. 😉

What can you do with a MIDI file? You can visualize the playing in greater detail on GarageBand, or adjust its tempo and transposition, and change to other cool sounds, on the 4D Music Player.
