WDM is the preferred choice. Mack W4AX Alpha Tester0

These are different audio APIs supported by Windows. They have different characteristics. MME uses the oldest Windows audio API which does not offer good play/record latency. DirectX improves this, but still imposes a penalty of 10s of milliseconds due to the system mixing of streams from multiple applications. WDM-KS avoids the mixing penalty of DirectX, and has very good latency characteristics; better than DIrectX. In general, if you can get WDM-KS to work with your third-party audio application, then you should use it as Mack has indicated. Otherwise try DirectX next and MME last.0
