Matra Studio
What it is
Matra Studio turns music recordings into chord charts, notation, and Sargam. You can upload an MP3, WAV, or M4A file, or record audio in the iOS app; each recording can be up to six minutes. After generating a chart, you can review it, make corrections, and find it again in your Library. Charts can show chords, key, meter, melody, and Sargam, with confidence marks on chords. Matra identifies chords and key as its strongest outputs; staff notation is in beta and may be imperfect. Charts can be exported as PDF, MusicXML, MIDI, or text chord sheets, or shared through private read-only links. Sargam provides a reading option for singers, harmonium players, and people who learn through Sa Re Ga Ma. Matra is available on the web and iOS. Early access is invite-only, and free use is subject to fair use of about 20 recordings a day. Paid plans include one-time purchases and monthly subscriptions, with different recording amounts, token limits, and retention periods.
For and against
For
- Accepts MP3, WAV, and M4A recordings up to six minutes
- Charts can include chords, key, meter, melody, and Sargam
- Exports include PDF, MusicXML, MIDI, and text chord sheets

The verdict
Matra combines recording-to-chart conversion with correction, library access, and several export formats. Its strongest stated outputs are chords and key; users should account for the invite-only early access and the beta status of staff notation.
Who it suits
Matra suits musicians who want to turn recordings into editable charts, especially singers and harmonium players who read Sargam. It is available on iOS and the web, but early access is invite-only.
