Francis Carcia:

  Yes there is that problem of agc acting on all of the spectrum coming into 
the sound card over 96 kHz.  So I propose that as a standard when desired to be 
use that any agc applied needs to be both switcable on and off and also 
adjustable.  Even adjustable in time constant which mere capacitors can 
accomplish.

  My first view of agc was to sample the output from the sound card of the 
desired signal level and use that.  A better idea then, to use the audio output 
of the sound card to control itself going into the final audio amplifier 
section external to the PC in the monitor system.  This way only the desired 
audio will have agc applied.

  Sometimes however it might be desirable to have some agc in the receiver and 
so as I mentioned above that can be switchable.  Again the better idea for that 
is to use only the sound cards output as the signal that controls the receiver 
as well as the external monitor gain.
