Piano source profile
Chords are supported, but resonance creates cleanup work.
- What the model hears
- The converter can place simultaneous pitches into polyphonic MIDI instead of reducing the part to one note.
- What needs attention
- Pedal resonance, repeated notes, dense voicings, and room reflections can produce extra or missing events.
- Best use here
- Record close to the instrument, keep backing audio low, and plan to review timing and sustain in the editor.
How it works
Capture the performance, continue in MIDI
Use a recording with audible note attacks and as little background noise as possible. The result is a starting point, not a claim of perfect notation.

- 02Trace the polyphonic performanceThe model estimates simultaneous pitches and returns a full MIDI draft to inspect.
- 03Tame resonance and timingReview chords, pedal tails, and repeated notes in the editor before export.

Straight answers
Before you upload
Is this converter really free?
Yes. You can run up to 10 conversions per UTC day without creating an account or entering payment details.
Do you limit the result to 30 seconds?
No. We process and return the full uploaded track within the product limit of five minutes and 50MB.
How long are my files kept?
The uploaded source is removed after the provider reaches a terminal state. The MIDI result and job record expire within 24 hours. Your browser keeps a local copy of the source only so you can replay it on the result page.
Can the converter recognize piano chords?
It can produce polyphonic MIDI, but dense voicings, resonance, and sustained pedal can create extra or missing notes that need editing.
Does this create sheet music from piano audio?
No. The output is a MIDI file and a note preview, not engraved sheet music or guaranteed notation.
How does sustain pedal affect piano MIDI?
Pedal resonance can extend or blur notes and may create extra or missing events. Review sustain and timing in the editor after conversion.
