Open respiratory-sound research

Listen closer.
Detect earlier.

A machine-learning toolkit for identifying COPD-related respiratory sounds — designed to make clinical audio more legible, one breath at a time.

The premise 01 — 04

Breath carries
information.

COPD changes the way air moves through the lungs. Those changes leave traces in sound — wheezes, crackles, and quiet moments that can be difficult to hear consistently.

SHWASA turns respiratory recordings into structured signals that researchers can inspect, compare, and improve.
