What is the best software to use for conference podcasting?

d.anconia asked:


Essentially I want to record *high quality* audio between me and someone who has a mic with their computer but who lives in a completely different city. How do I make sure that we both have high quality audio between our connections while also being able to record both my mic and theirs?

I need a program/software that can do this, and preferably do it well. If the program is well-known then price is not really an issue.
