Envelope Measure and Track

Envelope Measure and Track.  This computes an M-length exponetial average of the N-length block maximum
of the magnitude of the high byte of the input samples.  This is an estimate of the current loading of
signal from 0 to 128.  A vaule of 75 to 100 is reasonable loading for an A2D in most environments.
Setting this key adjusts the parameters for the EMT function as described in the EMT flag help file.
This function is performed on the base card so it can be used behind analog or digital modules.
