Help with device driver design decisions (based on sysvad virtual driver sample)

[Flavio_M_O]

Hi all,

I'm another developer with no previous experience in driver development asking
for some help

I landed in a new project where the main requirement is build a noise removal effect
that will be available system wide, for all applications that have access to soud input/output
devices lile Skype, Slack, MS Teams etc.

As Windows audio driver development is a broad field, I'm really lost so I started reading documentation and ended up in
the sysvad sample driver.

Looking more carefully in the sample code altoghether with documentation, I could not connect the points
about how to process the buffers from virtual devices and send the processed buffer to a real audio adapater.

After reading some threads in this forum, I found precious information that gave me a direction to start some
high level designing.

I'd like to share this design and, if possible, have some guidance
from you.

This can be a feasible approach for the solution i'm looking for?

There's any better or easier way(s) to approach this problem?

Any information from you to put some light on this would be great!


Thanks!
