How pitch feedback works
After you press Start, your microphone captures ~93 ms frames at 44.1 kHz. The pitch estimate is sent to the server, where YIN returns the authoritative fundamental and cents offset. Audio frames are not stored.
Without a selected rāga, the offset uses the nearest keyboard semitone as a quick landmark. With a rāga context, it reports drift from the swara's 22-śruti position.
