Ummm, I think I might know, I'm not really sure, but I could try to figure out if I know if you want me to. I think.

Another one you can look at is Skype, at http://www.skype.com/.

Probably the cheap and dirty way to do it is to set the mic to be included in the ouput and then record on line-out. Basically, it would require you to put the recorder between the computer and your headset/speakers, like recording traditional phone conversations. If you prefer doing it digitally, there may be a way to record line-out without changing the input on the soundcard mixer (which should be set to mic or line-in). Hope this helps :)

In the speculation category, if you have a PC, I've heard all sorts of great things about Total Recorder's ability to handle streamed audio. It seems that the Yahoo! chat would come under that. It's shareware, so you can try it out first. You might have to tweak things to get both ends of the convo, though.

I second the Total Recorder recommendation. Happy user for 2 years now. They continue to provide me free upgrades.

I was unable to record both ends of teh conversation with Total Recorder and USB Mics, so unless you can specifically tell me how ... (it only records the mic on my computer when I have it plugged in and speak, and it only records the incoming sound from the person on the other end when my mic is unplugged and they speak)

Okay, just what the hell are you and Goldstein up to anyway? Sounds like it has national security implications...

JWebb: I was wondering the same thing...what a couple of teases these two are. ;-)
