![]() ![]() I tested the new drivers mentioned and successfully got lower latency and smaller buffer sizes, but the only drivers mentioned seem to be the "High Definition Audio Device" driver, which I traced to hdaudio.sys. I'm measuring about 80ms round trip using USB microphone and audio devices. I used the WASAPI but the latency still isn't quite low enough. ![]() Most notably, support for <10ms audio buffer sizes with newer drivers. I eventually found this documentation which indicates the WASAPI in Windows is the lowest level you can get to, and there are even some improvements in Windows 10 to make the latency even lower. I've been working on some WinAPI code to try to get audio latency as low as possible in Windows 10 natively.
