Lossless, always
Bit-perfect FLAC at each recording’s native resolution. Nothing lossy, ever — streamed, never downgraded.
Decades of ragas, gharanas, thumris and film songs — collected, catalogued and loved over a lifetime by Ashutosh Chowdhury, now a living streaming archive for the family that has always shared it.
The genesis
For decades, Ashutosh Chowdhury gathered this music — thousands of recordings on shelves of CDs, each one logged, cross-referenced and annotated by hand. A spreadsheet grew, year after year, into an encyclopaedia of a family’s listening: which raga, which gharana, which artist, recorded when.
RagaStream carries that work forward. Architected by Anshula Chowdhury, it digitises every recording in lossless quality and weaves it into an archive you can actually explore — by raga, by mood, by the artists and lineages behind the music — so a lifetime’s labour of love finally becomes something the whole family can hold in their hands.
What’s inside
Bit-perfect FLAC at each recording’s native resolution. Nothing lossy, ever — streamed, never downgraded.
Ask for “something meditative for a rainy evening.” A knowledge graph of ragas, thaats and seasons finds it.
An AI guide to the theory, history and context behind the music — narrated, if you like, in a familiar voice.
A living collection, continually enriched with the stories behind each raga, gharana and artist.
The intelligence behind it
Every raga, thaat, taal, gharana, artist and mood is linked in a knowledge graph — a semantic map of Indian classical music. A raga knows its parent scale, its hour of the day, its season and its emotional colour; an artist knows their gharana and the teachers they descend from.
And it doesn’t only remember what’s written down — it infers. It derives a raga’s time of day from its thaat, traces a full guru–shishya lineage across generations, connects ragas that share a scale or key notes, and carries a raga’s mood down to every recording — so a search by feeling finds the right music even where the catalogue is quiet.
Ask how Yaman differs from Bhairav, or what the Kirana gharana is known for, and RagaGuide answers from those same grounded facts — never inventing. And it can speak: narrated in Ashutosh Chowdhury’s own voice, recreated with a fine-tuned voice model, so the collection explains itself in the voice that gathered it.
For the family
RagaStream is not an app available to the public. Exclusive access is reserved for family members only, to learn from and enjoy the collection that Ashutosh Chowdhury lovingly and diligently curated over decades. There is no public sign-up.
