We use Skype for the TUAW Talkcast and recently, our host and podcasting guru (OK, not guru, but he is the host and we like him), Michael Rose, has been looking at possibly using Ecamm's Call Recorder 2 plugin as an option for recording our weekly talkcasts. I actually have used it to record both audio and video chat for the Squadcast and really think that it is a fantastic, fantastic add-on.
For anyone unfamiliar, Call Recorder is a great little tool that adds a recording window to Skype. This makes it easy to record incoming and outgoing calls (audio and video). The files are saved in the QuickTime format and they can be converted to MP3 or split into separate tracks.
With the release of the latest version of Skype for the Mac, Ecamm has updated Call Recorder as well. In addition to the latest Skype compatibility, Call Recorder 2.3 also includes a new two-track video recording option (so that you can have a separate stream from each side of the conversation) and enhanced video recording quality.
Call Recorder 2 is $14.95 (for $7 more, you can also get Conference Recorder, which adds the same functionality to iChat, and unlike the built in iChat recorder, doesn't require both users to have Leopard) and a free demo is available if you want to try out the tool.
If you want a simple, hassle free way to record Skype conversations, give Call Recorder a shot!
