/*!\brief This value is the minimum threshold, calculated by averaging all
* of the samples within a frame, for which a frame is determined to either
* be silence (below the threshold) or noise (above the threshold). Please
* note that while the default threshold is an even exponent of 2, there is
* no requirement that it be so. The threshold will accept any value between
* 0 and 32767.
