What you would do is make up a "software component hardware ID" for your APO. 
It would begin with APO\....

An IHV that wanted to use your APO would put an AddComponent line in their .inf 
that referenced your APO.

INF AddComponent Directive - Windows drivers | Microsoft 
Docs<https://docs.microsoft.com/en-us/windows-hardware/drivers/install/inf-addcomponent-directive>

You would author a driver package which was targeted to this hardware ID, 
certify it, and put it on Windows Update.

Hi! Tim:
    Thanks for your kind reply.
    The APOs will be installed with a specific hardware, such as HDAudio 
device, USB audio device.
    My question is when qualifying the APOs in WHCK, and submitting WLK 
signature for catalog file, is the software itself acceptable? Or the APOs 
should be associated with a hardware by an IHV(independent hardware vendor) to 
be qualified WHCP?
   We are not IHV, don't have any hardware products. We sold only software, and 
wanna have our algorithm certified by WHCP.

  Best Regards.
  Wayne Wang

Could the APOs be verified against WHCP alone without any hardware
audio device, and get signed or get a logo?

No,  Officially, APOs are part of a driver and must be associated with a
specific piece of hardware.  You can't install an APO independently or
generically.
