WDM or WASAPI
Posted: 03 Oct 2021 18:12
WDM is the ‚old‘ Direct Sound device model.
Since Windows 10 this is replaced by the new Windows Audio Session API (WASAPI). WDM is only ‚emulated‘ on Windows 10 for backward compatibility.
As such, please use the WASAPI model whenever possible.
Only if you experience any issues with WASAPI (eg. with older or badly implemented device drivers) you might try WDM, if that gives you more stability - but on all newer devices, you should only use WASAPI.
But never mix WDM and WASAPI !
If you want a more professional solution with even less latency, use the ASIO model.
