Note, however, that I only did the driver work. The algorithm work was all done by the client. I was working with a group of audio processing gurus who have more letters after their names than I have. They knew the algorithms, but they didn't know drivers. That's why they hired me. I have very little visibility into the processing library itself. I just feed them packets. > Did you make any attempts to pursue a GFX/LFX framework for AEC as > we've been discussing? > No. We had to have a WDM filter for XP anyway, and since the WDM filter was going to work in Vista (because it's not a WaveRT driver), it didn't make sense to pursue a capture APO. -- Tim Roberts, timr@xxxxxxxxx Providenza & Boekelheide, Inc.
