How to Profile Sound Card?

Hello,
I’ve modified the audio rendering components of the engine and I want to know if what I did improved the performance of audio rendering. Since I can’t use CPU nor GPU profilers to see this, I want to know if there is a profiler for sound cards?
If there is none for the unreal engine, is there one that you can recommend for windows?
Thanks in advance.

If you are not able to measure your performance, how do you know audio rendering needed changes to improve the performance? Always measure first, then try to optimize, then measure again if it really helped!

Also: Nowadays audio rendering is almost exclusively done on the CPU, so the CPU profiler should help. You can also add a few more “profiler stats” in the audio code if you need more detailed performance information for that part of the engine.
