As a fair weather participant in PodcastMN — a Minnesota-based group of podcasters — I answered a question on the listserv today about Skype or iChat recording that I realized would make a good post others might find useful and yes, this is Mac-centric since I no longer use a PC except when needed via Parallels.
I’ve used both Skype and iChat extensively for interview or conferencing/project scenarios and have recorded them both (even using their respective video capabilities…but that’s another post topic). Two ways I’ve found to be optimal for audio recording:
1) The easy way is with Audio Hijack Pro (AHP) or Wiretap. I’ve had the best success with AHP so that is my recommendation. They have set up a no-brainer quick Skype or iChat recording function and have detailed a how-to on their web site (and you can also download a demo so you can try it out first).
There are other software solutions (like CallRecorder) but they’re limited and you won’t be able to grow with them as you get better. The kicker with AHP is that as you grow and become more sophisticated in what you want to accomplish, the software has deep and highly functional capabilities that you can spend hours playing with to get a more perfect sound and geek-out with routing audio signals!
2) Setting up a “mix minus” from your mixer or Firewire/USB box so that you can record the iChatters or Skypers on one channel and you on the other channel so you can fix any problems or normalize audio levels in post production. My preference is to record *both* an internal recording on my Mac with AHP *and* a backup recording out to my M-Audio Microtrack to make certain I’ve captured it and there are no hiccups. Saved my bacon twice when doing sessions for one of my clients earlier this year.
