How do I package a data transform filter so that it becomes part of the graphs that get built for people doing audio recording types of application? Here's a bit of background. I have a data transform algorithm that I want to interpose into the realtime capture stream from whatever sound card happens to be installed. I initially built this as a DirectShow filter, and I'm able to test this quite easily using GraphEdt. Now it's time to package it for the real world, where people just hit the record button in applications like CoolEdit. I can't figure out how to get this filter installed into the graph that gets used for the realtime data stream. Should I even be using a DirectShow filter in the first place? Should this instead be an AVStream filter? Or should it be a regular WDM filter driver that sits in some device driver stack modifying some IRPs? If so, *which* device driver stack is the right one? ****************** WDMAUDIODEV addresses: Post message: mailto:wdmaudiodev@xxxxxxxxxxxxx Subscribe: mailto:wdmaudiodev-request@xxxxxxxxxxxxx?subject=subscribe Unsubscribe: mailto:wdmaudiodev-request@xxxxxxxxxxxxx?subject=unsubscribe Moderator: mailto:wdmaudiodev-moderators@xxxxxxxxxxxxx URL to WDMAUDIODEV page: http://www.wdmaudiodev.de/
