Synthesia
Turn any piano recording into a Synthesia file
Synthesia needs a MIDI file, and most recordings do not come with one. Upload the audio, download the MIDI, and open it in Synthesia to watch the notes fall.
One free transcription a week of the first 2 minutes of a recording, no card required. See plans

WAV · MP3 · FLAC · OGG
Free transcriptions cover the first 2 minutes of a recording; anything after that is left out. Paid plans go up to 15 minutes.
Transcribing needs an account — we’ll hold onto your file while you sign in.
Two hands, two colours
A falling-notes display is far easier to learn from when the hands are different colours. Tick "Separate hands" before uploading and the MIDI comes back with a right-hand track and a left-hand track, which Synthesia colours separately.
Each hand stays on the same track from the first bar to the last, so the colours do not swap partway through.
Learn it at your own speed
Once the recording is a MIDI file, Synthesia can slow it down, loop a section, wait for you to play the right note, or show one hand at a time. None of that is possible with the audio alone.
How to do it
Upload the recording here, tick "Separate hands", and pick the style of the piece. Download the MIDI when it is ready, then open it in Synthesia with File, Open or by dragging it into the song list.
The same file works in other falling-notes and piano-roll apps that read standard MIDI.
Questions
Do I need Synthesia to use the MIDI file?
No. It is a standard MIDI file. Synthesia is one popular way to view it, and any DAW or notation program will open it too.
Why is a note in the wrong hand?
Hand separation is worked out from the notes alone, and where the hands play close together it is sometimes wrong. You can reassign a track in Synthesia or fix the note in a MIDI editor.
Can I make a video of it?
Yes. Record your screen while Synthesia plays the file, or use Synthesia’s own video export if your version has it.
