WDM simply stands for "Windows Driver Model".krizrox wrote:
Which leads me to another question: WDM drivers. Supposedly CW supports that right? Wasn't that pretty much the standard for Sonar up until version 3? What are WDM drivers? Where do I find them? I didn't see any reference to WDM in the list of available drivers (or is that simply the wave drivers). How many channels of WDM can I load at one time?
It describes the framework for writing a device driver for Windows '98, ME & 2000. It's a generic framework, not necessarily 'audio-specific'.
IIRC, the 'audio (or video)-specific' variant is called "WDM Connection and Streaming Architecture", which utilises kernel-level streaming of the data. I think that there's greater latency going through the kernel than e.g. using ASIO drivers (although that latency was improved in XP, I believe).
