The algorithms used may utilize simple statistical models based on sound energy or may involve sophisticated comb filter networks or other means.
where bpm stands for beats per minute. The HR is often used to compute the heart rate variability (HRV) a measure of the variability of the time interval between heartbeats. HRV is often used in the clinical field [ 6 ] to diagnose and monitor pathological conditions and their treatment, but also in the affective computing research to study new ...
Metric levels: beat level shown in middle with division levels above and multiple levels below. In music and music theory, the beat is the basic unit of time, the pulse (regularly repeating event), of the mensural level [1] (or beat level). [2]
The Breathometer was a small device that plugged into the audio jack of a smartphone, coupled with a dedicated app that reads the user's blood alcohol content (BAC). [8] [19] [20] [9] The app utilized the smartphone to provide the processing power, which allowed the device to be small enough to fit on a standard keychain.
