Windows does not do such a thing as you describe; what gave you that
impression?

Subject: [wdmaudiodev] Loop back AGC in renderer audio path?
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
