The latest Windows installations have a global effects filter
(WMALFXGFXDSP.dll).
Here is the driver stack for USB audio on my laptops.
It appears that this has been around since October 2013
I did a search on the Internet for what the purpose of this DLL is but came
up empty.
I have two questions.
1) What is the purpose of this DLL (possibly environmental audio for
gaming)?
2) If we develop a GFX filter will it install if there is already a GFX
filter?
Thanks,
