[AG-TECH] how do I get desktop audio 'into' AG/RAT?

[Andrew Leahy]

Ta.

BTW just found with RAT under Windows you can change the Input to 'Stereo
Mix' which grabs the local audio output rather than the Mic In. So using
this along with VPCScreenProducer provides a basic way for users want to
push media from a Windows desktop.

Cheers, Andrew
