ANURAVA Sound Passport
Every instrument has an acoustic identity.
No two hand-forged instruments are perfectly identical. ANURAVA measures and documents individual professional instruments so practitioners can understand the instrument they are selecting — not just the product family it belongs to.
What a passport contains
Six parts of one record.
Identity
Instrument ID, product family and craft batch — the reference that ties the physical object to its record.
Physical profile
Diameter, height, weight, material and finish, taken from the actual piece.
Acoustic profile
Fundamental frequency, approximate note, dominant overtones where measured, and sustain.
Sound character
Qualitative description of how the instrument responds to strike and to rim play.
Media
Photographs and recordings made from that exact instrument, labelled as exact-piece.
Craft & inspection
Recording date, inspection date, and a verification link for the instrument.
Product versus instrument
A model describes a family. A passport describes a piece.
A product page tells you how a model is made, what it is made from and what sizes exist. A Sound Passport belongs to one physical unit — the bowl or gong that will actually arrive — and records what was measured on that unit.
Because each instrument is made by hand, exact pitch, response, sustain and overtone behaviour vary from piece to piece.
Representative versus exact-piece audio
Representative audio demonstrates a category. Exact-piece audio belongs to the individual instrument being offered. Every recording is labelled accordingly.
Values are recorded from the individual instrument. Fields that were not measured are left blank rather than estimated.
After the sale
The record stays valid.
When an instrument is sold, its passport URL keeps working. The documentation belongs to the instrument, so its provenance remains verifiable for whoever owns and plays it.
