Hi,

While developing an SFX APO (renderer), I have encountered some problems 
causing my output to exceed legal range - this is being addressed.
However, while looking into this, I got the impression that Windows (I presume) 
monitors the output level of the APO, and is able to apply AGC-like 
functionality by adjusting the input gain to the APO.

I would really like some info on this functionality, including:

  *   How does this work?
  *   Are time constants described somewhere?
  *   Can it be tuned or adjusted in any way?

Best regards / Med venlig hilsen
