GfxSwap - Recording

NTDEV
1

Hey guys,

I am evaluating now what is most efficient way to process audio data. So I found another example in the DDK 3790, GfxSwap.

It worked fine in swapping the playing out audio. Question is that How can I change this code to swap the recording data? I think the basic frame is almost same. Am I right? Which part is need to be changed?

Thank you.

Not a direct answer to your question, but a warning- the capability this demonstrates doesn’t exist on Win2K, nor on Vista [unless something changed after I left the audio group, which is certainly possible].

You might want to ask for some suggestions about what you want to do on the wdm audio newsgroup.

Thanks Bob,

I am thinking of doing this for XP and later on for Win2K. ( I 've read somewhere it is working for win2k though.)

I knew that it won’t work on every platform, but there isn’t an absolute solution for every platform though. If it is a filter driver, it will work for XP and 2K but not for Vista. For vista, as far as I know, LFX/GFX is the only way to do it.

Thank you again.
