A query to the selected Harmonicity object.
the mean value, expressed in dB.
The mean harmonicity between the times t1 and t2 is defined as
|1/(t2 - t1) ∫t1t2 dt x(t)|
where x(t) is the harmonicity (in dB) as a function of time. Frames in which the value is undefined (i.e. in silent intervals) are ignored. If all the frames are silent, the returned value is undefined.
