Web music transcription studio
A transcription studio built for review.
Upload a recording, then inspect the declared result.
Matra is currently a web studio. Declare the tradition, material and recording role before analysis; the result can include some lenses and omit others. 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.
- MP3, WAV or M4A audio upload
- Harmony with per-chord confidence when available
- Staff, Hindustani or Carnatic views only when produced
- Canonical score correction with revision history
- Capability-scoped PDF, MusicXML and MIDI export
Questions, answered.
Where does Matra run?
The current product is the Matra web studio. This page does not promise a native mobile app or a mobile release date.
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.
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.
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.
