Matra Studio

What Matra Studio is

Matra Studio turns music recordings into chord charts, notation and Sargam, a way to read music through Sa Re Ga Ma. You can upload an MP3, WAV or M4A file, or record audio in the iOS app; each recording can be up to six minutes. Matra generates a chart that you can review, correct and revisit in your Library. Charts can show chords, key, meter and melody, with a Sargam view and confidence marks on chords. Matra describes chord and key results as its strongest outputs. Staff notation is in beta and may be imperfect.

Charts can be exported as PDF, MusicXML, MIDI or a text chord sheet, or shared through a private read-only link. Sargam is aimed at singers, harmonium players and people who learn through Sa Re Ga Ma. The service runs 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 allowances, token amounts and retention periods. Matra says recordings are deleted after processing and not used to train its engine; anonymous charts and their audio are purged after 48 hours.

Who it suits

Matra suits musicians who want to turn recordings into editable chord charts, and singers or harmonium players who use Sargam. It may also suit people who need exports such as MIDI or MusicXML, or a private read-only chart link.

Limits

Early access is invite-only, and free use is subject to fair use of about 20 recordings a day. Paid plan allowances and retention periods vary: Starter is 2.99 USD once for about 10 recordings kept 90 days; Studio is $4.99 a month for 450 Tokens, about 32 recordings and no rollover. Other paid options have their own recording or token limits and retention periods.

Verdict

Choose Matra Studio if you want recording-based chord charts with Sargam, editable results and several export options. Look elsewhere if staff notation is your main requirement, since Matra says that output is in beta and can be imperfect.
