Broadcasting audio from Teamspeak 3 or Discord to Icecast 2?

I’ve set up and installed Icecast 2 on my server and have verified that I can transmit my microphone to the Icecast 2 server but I want to conduct interviews. Since we are a gaming community, we tend to use either Teamspeak 3 or Discord for voice chat. Is there a way to pull audio from these applications and just broadcast it live to my Icecast 2 server? I’m not sure how best to do this as I am entirely new to internet radio.

been wondering the same thing myself. Could probably do it with virtual cables, but haven’t toyed around with it yet.
