Skype Call recorder - Noise floor gest too high

Hi all,

I have a client that uses Ecamm's wonderfully simple "Call Recorder" for skype to record podcast interviews. (http://www.ecamm.com/mac/callrecorder/)

The "guest" side of the call always records crystal clear. Occasionally however, the "host" side (on whose machine Call Recorder is running) the noise floor will start OK, and then after about 8-10 minutes step up in to unacceptable territory. This noise does not appear to be "acoustic" - in other words it does not sound like it's coming from the mic from a fan kicking on, etc.

My theory is that this is a bandwidth issue, but then I'd imagine the noise would step up on both channels. Any thoughts on where the culprit might be, or can any one in this forum recommend a better system for recording these calls? Budget, of course, is tight.

Thanks,
Stace
