I hope that was clear enough!
Perfectly clear. You're making The Standard Podcast. You forgot adding music at the appropriate points. Themes, stingers, etc.
They both record their audio in to audacity
And that is, almost without question—given you can pull it off, the best way to do it. The podcast show sound never goes through Skype.
Given you're already advanced beyond simple two-person interviews, my opinion is go straight for the two computer setup.
That worked for me because I already had two machines (one much older) and a simple sound mixer. You let Skype have its way with the machine on the right and the machine on the left records the mixed show (in Audacity) and creates the music from an iTunes playlist. That's perfectly valid as with most computers, Record and Play are two completely separate jobs anyway.
If you have no music, the recorder doesn't have to be a computer. If you have a Personal Audio Recorder, you can use that instead of a computer. Also I cheated supersonically. Both of those Macs have perfect Stereo In and Stereo Out. They will directly
interface with the mixer. Almost all new Windows laptops won't do that and Macs won't, either.
Please note the more comprehensive techniques do have shortcomings. You will be recording the Final Mixed Show. No Option. There is no making Sally in Schenectady louder in post. There is no post. Audacity can't take apart a mixed show.
And you will be recording Skype and whatever Skype decides to do with the sound. My Up Link at home sucks. So my Skype voice is terrible when it arrives at a destination. Since I originate the show, it doesn't matter (to me).
