  • DETECTING RESPIRATORY RATES IN AUDIO USING AN ADAPTIVE LOW-PASS FILTER
    Publication number: 20190021633
    Abstract: An example apparatus for detecting respiratory rates includes an audio receiver to receive audio including respiratory sounds. The apparatus also includes an adaptive low-pass filter to process the audio using an adaptive bandwidth based on a mean breath rate to generate an envelope. The apparatus further includes a peak detector to detect a plurality of peaks from the envelope. The apparatus includes a respiratory rate calculator to calculate a respiratory rate based on the detected plurality of peaks.
