Hi, I'm in a hurry and I couldn't find out how to do this. I have a digital tuner box which then goes into a capture card on a PC which then streams it out across the network. I work at a school and we're showing them all the England World Cup game so they don't just skip school to do it instead, not to mention most of the teachers want to watch it as well. This is all working fine but I have a vuvuzela app for my iPhone which I want also inputting into the stream so they can hear both the commentary and the vuvuzela app when I decide to use it. I need both at the same time because I want to be able to drown out the commentary with the vuvuzela and I still want them to be able to hear that there is some exciting commentary going on but I don't want anyone to be able to make out what they're saying. I was just going to use an audio splitter to do this but one of our tech teachers lost them all. Is there any way of doing this in the software?
