id like to capture both a capture and render stream to perform some echo 
cancellation on an audio stream in Vista, However the LFX/GFX archiecture does 
not lend itself well to full duplex support.
My question is could one use a GFX to collect render data and an LFX to collect 
capture data and use shared memory for the LFX to process the GFX rendered data 
that was collected? Also is there anyway to synchronize an LFX and GFX in this 
Thanks Pete.
