Which piano source works
| Source | What to expect | Route |
|---|---|---|
| Phone or mic recording of a real piano | Good if the room is quiet and the mic is close | Convert directly |
| Studio or digital-piano audio export | Best: clean tone, no room noise | Convert directly |
| Piano inside a pop or rock song | Fair: the extracted stem keeps some bleed from other parts | Piano extractor, then convert |
| Piano with strings or a full orchestra | Rough: the model hears every sustained note | Extract if you can; expect heavy cleanup |
| Fast classical runs with a lot of pedal | Some notes blur or merge | Raise the shortest note, then edit |
Piano is the instrument this kind of model handles best, because notes are struck, decay and overlap in a regular way. It is still a transcription, not a copy: check it against the recording.
Getting the piano out of a song first
The piano extractor uses a 6-stem separation mode that gives piano its own file. Quality depends on the song: the piano stem is weaker than vocals or drums, so it may carry some guitar or synth. Listen to the stem before you convert it.
- Open the piano extractor and drop the song.
- Download the piano stem when it finishes.
- Drop the stem into the converter on this page.
Recording a piano clip that converts well
- Put the phone or mic about an arm's length from the strings or speaker, not across the room.
- Turn off fans and music in the room; steady noise shows up as phantom notes.
- Play slightly slower than usual the first time; fast, blurred passages are what the model misses.
- Record in a lossless or high-quality setting if your recorder offers it, then export MP3, WAV or M4A.
- Keep each clip under 6 minutes.
Cleaning up the result
| Problem | Fix |
|---|---|
| Lots of tiny extra notes | Move the notes slider toward fewer and raise the shortest note |
| Quiet notes are missing | Move the slider toward more |
| Notes an octave off | Common on low bass notes: transpose that region in your DAW |
| Held notes chopped up | Raise the shortest note; merge or lengthen them in the piano roll |
| MIDI sounds stiff | The notes are not quantised on purpose; use your DAW's quantise if you want a grid |
The file has notes and velocities only: no sustain-pedal data and no left- or right-hand split.
Frequently asked questions
Is there a piano-specific model?
No. It uses Basic Pitch, a general polyphonic note model from Spotify, which handles solo piano well. We do not claim a piano-only model.
Can I convert a piano from a song?
Yes, with a detour: split the piano out with the piano extractor, then convert the piano stem. The stem from a busy mix is rougher than a clean piano recording.
Is it free and private?
Free with no sign-up and no trial limit. The audio is processed in your browser and never uploaded.
Does it capture the sustain pedal?
No. You get notes, lengths and velocities. Add pedal events in your DAW if you need them.
Does it separate left and right hand?
No. All notes go on one track. You can split by pitch in your DAW.
How long can the piano recording be?
Up to 6 minutes per file. For longer pieces, cut the audio into sections first with the audio cutter.
Can I get sheet music from the MIDI?
Open the .mid in a notation app such as MuseScore. Expect to correct rhythm and note lengths, because the MIDI follows the performance rather than a written score.
