+/*!\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.
