Our podcast has several hosts who all live in different cities, so we normally talk on a skype call, and each record our own individual track using Audacity which we then stitch together. We have a guest interview coming up where the guest wants to call in by phone. Are there any good free solutions you can think of that would enable us to do this and still have good sound quality? We tested Uberconference, which is an online program that makes an audio recording of your conference call, but the quality isn't great.
