Phase 2 expands the corpus toward 500+ hours and adds the Carnatic tradition. Enterprise partners get priority access.

Every recording, documented like a research object.

Each track carries a metadata record designed for both training pipelines and musicological analysis, organized across five categories:

1. Performance parameters.

Raga classification, tala identification, melodic markers, tempo, dynamics.

2. Performer information.

Artist lineage (gharana), experience, training history.

3. Cultural context.

Raga etymology, emotional framework (rasa theory), seasonal appropriateness.

4. Technical analysis.

Pitch contour data, ornamentation catalogue (gamakas), rhythmic complexity metrics.

5. Preservation and rights.

Artist compensation records, consent documentation, archival status.

The sample dataset

Six tracks, one per instrument, drawn directly from the corpus. Each preview streams at reduced resolution with an audible watermark, and each card shows a live excerpt of the track's annotation JSON. What you hear is a demo. What we license is 96kHz / 24-bit multi-stem masters with the complete 80-field record.
