iChat and selected audio
I have an issue with iChat on the Mac. When I select my audio interface where my mic plugs in I get all audio going through that interface in both directions. Meaning if I play any sounds iChat hears them all. This is partly a side effect of my having a mix minus setup going to an external mixing board. What I need is an interface that ONLY lets iChat hear my microphone and any other applications I specifically select.
I found that if I use my Wiretap Anywhere (http://www.ambrosiasw.com/utilities/wta/) and setup an input with the interface my mic goes into plus say my Soundboard (http://www.ambrosiasw.com/utilities/soundboard/) program and select that as the input in iChat then it works perfectly. Now only my mic and selected audio is heard by iChat. I suspect that using WTA ensures that only the input side of my Griffin iMic (http://www.griffintechnology.com/products/imic) is being sent through the virtual audio interface to iChat. I use the outbound side to send system audio out to my mixing board. That is likely why iChat hears everything. It's grabbing both in and out of the selected interface. Using WTA seems to clip that. Regardless if I am right it sure solves my problem.
