For songwriters · voice & humming
The tune in your head, on paper.
Sing a line, then inspect what the engine can support.
Upload a voice memo you can process. 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. A clean solo line is useful context, not an accuracy guarantee.
How it works
- 01
Sing or hum it
Upload a voice memo. Declare solo lead vocal when that description is accurate.
- 02
Inspect the notation result
The engine may return Staff, an Indian Sargam lens, other declared capabilities, or a reason for abstention.
- 03
See what to check
Review declared confidence and maturity, then edit the canonical score. 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.
- Harmony with per-chord confidence when the Harmony lens is available
- Declared key, tempo and meter when supported by the result
- Staff notation when the Staff lens is available
- Separate Hindustani and Carnatic Sargam lenses when produced
- Transpose the editable score when musical notes are available
- Capability-scoped PDF, MusicXML and MIDI export
Questions, answered.
Does humming really work?
A clean, close monophonic line can be suitable input, but no source type has a universal success or accuracy promise. The engine can abstain.
Is my singing kept 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. Audio is not used for model training.
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.
Built with the musicians who use 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.
