More Information
Summary:A device for calculating cardiovascular heartbeat information is configured for receiving an electronic audio signal (10) with information representative of a human voice signal; generating a power spectral profile of a section of the electronic audio signal, and detecting a fundamental frequency (F0) of the generated power spectral profile; generating a denoised audio signal (45); generating a time-domain intermediate signal (55) that captures frequency, amplitude and/or phase of the denoised audio signal; detecting and calculating heartbeat information (65) within a human cardiac band in the intermediate signal.
