Piano · your own playing
Transcribe your piano recording.
Preserve an idea as an inspectable, correctable score draft.
Declare piano and the truthful recording role, then upload audio you have the right to process. Polyphonic or noisy material can reduce confidence or cause abstention. Matra shows only the musical views the engine produced for that recording. If a view is unavailable, the Studio explains why instead of inventing a result.
How it works
- 01
Declare, then upload
Upload audio you have the right to process. Add musical context when you know it.
- 02
Open the declared result
Matra shows only the musical views the engine produced for that recording. If a view is unavailable, the Studio explains why instead of inventing a result.
- 03
Fix, then keep it
Editing always improves your chart. Your corrections (never your audio) also help improve Matra’s engines, separated from your account, unless you turn that off in Account › Privacy. Edit the current score, then export PDF, MusicXML or MIDI when that format is available for the result.
What you get
The result lists only the views and exports the engine produced.
- Staff notation when the Staff lens is available
- Harmony with per-chord confidence when available
- Declared key, tempo and meter when present
- Current score correction with revision history
- Capability-scoped PDF, MusicXML and MIDI export
Questions, answered.
Does it work on a room recording of my piano?
The web studio accepts supported audio formats, but room acoustics, overlapping notes and other instruments can affect the result. No piano-recording accuracy level is universally promised.
How accurate is it?
There is no single accuracy promise for every recording. Each available result carries its declared maturity and confidence, and you can inspect and correct the chart before using it.
Can I get the chords of a famous song?
Matra accepts audio you have the right to process—your own playing, recordings or practice takes. It does not host a famous-song chart library, and the engine may abstain from unsupported or uncertain results.
What does it cost?
Invited members are not charged for analysis during the current private beta. Usage limits apply. Future credit, pack, subscription and discount policies have not been set.
Is my audio private?
Your recording stays private and can remain with your chart for playback or retry. Delete projects or your account yourself; see our Privacy Policy for retention and deletion. We never use your audio to train AI. Your corrections and your songs’ analysis (not audio) help improve Matra’s engines, separated from your account, unless you turn that off in Account › Privacy.
Built with the musicians who use it.
