You will also need a 100k ohm resistor after the capacitor to discharge the DC, so the input of your soundcard doesn't have to do this!
SH, I just came upon TrueRTA, and was going to try the free demo to see if I like it. Could you share the details about that little circuit you described so I don't have to drive to Jeff's and steal his mic whenever I want to use it?

Thanks!
