For transcribers & arrangers
Audio to MusicXML.
The first draft of your transcription, done in a minute.
You'll still apply your ear — but you shouldn't have to type every note. Matra drafts the transcription from audio: chords, key, meter and staff notation, confidence-marked so you know where to look first. Export MusicXML and MIDI when it's ready.
Free during early access · no card · private by default
How it works

Matra writes the chart
Chords, key, meter and melody — drafted in about a minute, with confidence on every chord.

Questions, answered
Is this a replacement for transcribing by ear?
No — it's the first draft. Professional transcribers use it to skip the mechanical pass and spend their ear where it matters. Confidence marks show exactly where to check.
How clean is the MusicXML?
Yes — export MusicXML and MIDI, aimed at opening clean in MuseScore, Sibelius, Dorico and Finale. You can also view the transcription with confidence marks in the studio.
What does it cost?
Right now — nothing. Matra is free during early access (fair use: about 20 recordings a day), and every file still shows its real Token price so there are no surprises later. The meter: about 1 Token per 15 seconds, a typical 3½-minute recording ≈ ◇14. When billing starts, early-access musicians keep ◇600 — plus half price for 3 months and 25% off the rest of their first year. Sargam and notation views cost nothing, ever.
Is my audio private?
Yes. Uploads are private by default, nothing you make is published anywhere, and we never train on your audio.
Built with the musicians who use it.
Matra is in early access. Fix a chord or a note the engine got wrong, and we gift you Tokens as thanks — your ear makes the engine better for everyone.
