From breath to signal.
A transparent audio workflow turns a short respiratory recording into two complementary research outputs.
One recording. A chain of evidence.
Switch research tracks to see how the same respiratory sound becomes a different question and output.
Record audio
Start with the respiratory recording as inspectable evidence.
How sound becomes a signal.
Follow one recording through the system. Each stage changes the question the model is able to ask.
A breath becomes a measurable waveform.
The microphone records pressure changes through a short, repeatable chest-sound protocol. Nothing is classified yet: this is the unedited evidence.
Capture
Standardized chest sound recordings from a small, repeatable protocol.
Clean
Patient-aware splitting, resampling, normalization, and fixed windows protect the evidence.
Represent
Waveforms become model-specific time-frequency features.
Predict
Each track returns its own probability or sound-event class for review.
