For Audio Fidelity Test, we created manual errata 4568 which will become
effective on Jan 1st, 2014. By referencing this manual errata in the
submission readme file, it will allow not running the test.
Hello wdmaudiodev people
I have a pressing issue on which it's hard to find definitive informattion:
HCK testing requirements for my USB Headphone/APO Driver product.
The background:
I have developed an APO to ship with a partner's USB headset - it does
virtualization and other DSP processing (it includes a mic and runs at 48k
and 96k)
I understand that to properly load in Windows 7 and 8/8.1 my APO must comply
with Windows Protected Environment, as described in
https://docs.microsoft.com/en-us/previous-versions/windows/hardware/cert-program/deviceaudio-requirements
<https://docs.microsoft.com/en-us/previous-versions/windows/hardware/cert-program/deviceaudio-requirements>
I understand this compliance requirement has been removed since Windows 10
(https://msdn.microsoft.com/en-us/ie/dn932547%28v=vs.94%29?f=255&MSPPError=-2147217396
<https://msdn.microsoft.com/en-us/ie/dn932547%28v=vs.94%29?f=255&MSPPError=-2147217396>)
So I have been looking at HCK testing
One of the tests is the "Fidelity Test" ( Device.Audio.Base.Fidelity), with
one of its requirements being the use of an Audio Precision Analyzer to check
audio IO fidelity
This analyzer costs in the region of $25000 and in MS docs I see mention of
analog outputs etc etc... so I'm really hoping that this fidelity test does
not apply to my case.
So my question is: for my USB Headset/APO product which includes a mic and
supports 48k and 96k sample rates, do I absolutely requiHCK certification for
my APO Driver to load properly on Windows 7/8/8.1 and, if so, does my HCK
testing regime require the Device.Audio.Base.Fidelity test?
Thanks,
Culann
