Questions, answered
How do I get notes for a bhajan?
Sing it (or play it) into your phone and Matra writes the sargam from your audio. Traditional and public-domain bhajans can be shared freely; film songs stay your private charts.
My Sa is at C# — does that matter?
Set Sa wherever you sing. Move it later and the entire chart follows — the sargam never changes, only the mapping.
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.
How accurate is it?
Chords and key are our strongest outputs and carry per-chord confidence so you always know what to trust. Staff notation is early access — honest but imperfect today, and improving as the engine trains on more recordings.
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.
