This is how to get at the data in the actual sample; if you want it available outside of the directshow framework, Dee Mon's answer is what you're looking for. – kidjan Dec 17 '10 at 22:33

Insert the Sample Grabber filter between file parser and audio card (or other renderer) and query ISampleGrabber interface. It will give you the data as it's passing through.
