My goal is to take Live AC3 (or DTS) from an optical input (e.g. from an XBOX), decode the signal, then drive the output to a directshow filter graph as six seperate channels.

From there, I want to play with a bunch of differnt room correction algorithms before sending it to the 5.1 speaker analog outputs but this I know how to do.

Any suggestions on how to get the input correctly into DShow?

Thanks,
Tom

What are the room corrections algorithms that you want to use?

If you succeed in doing what you want, the chances are high that the latency will be too high.

You would need some kind of asio host in a directshow source filter. I don't think it exists yet but maybe it does.

Maybe there are other ways but this idea seems to be a good one.

I tried to make one before but I had problems because of 6 audio channels. I was able to make a directshow source filter that passed 2 asio sound channels but I was never able to make it work with 6. It's not a problem with asio. It's as easy to get 6 channels as it is to get 2. It's my limited knowledge of directshow filter programming that caused this. I also had problems with multithreading. The code I based my plugin on (one of microsoft samples) used multithreading. Code from different source files ran at the same time. I had trouble getting the asio code and the filter code to work together and it is still far from perfect.
