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.
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.
Audio waveform
Capture breath cycles as a time-domain signal before any transformation.
