When we are recording Wealth Nation, we often conduct interviews via Skype. Of course, we’ve got a fairly sophisticated microphone setup going on, and I get everything tweaked just the way I want it before getting on the call. But then, in the middle of recording a show Skype decides to start changing microphone volume levels on me!
I’m not just talking about changing the volume level in Skype! I mean Skype reaches out and changes the main volume level on the laptop through the System control panel! It’s amazing. You can sit there and watch your microphone settings going up and down while your sound quality is all screwed up.
Well, I finally found a fix. It’s actually pretty simple.
- Quit Skype
- Open the following file with TextEdit: ~/Library Â» Application Support Â» Skype Â» shared.xml
- At the very end of the document, you’ll see an area that looks like this (but probably with more MicVolume numbers):
- Add one new line immediately after the
<AGC>0</AGC>: It should now look like this:
- Save the document, restart Skype, and enjoy your new peace and tranquility.
What this does is disables AGC, or Automatic Gain Control, by setting the variable to 0. Use “1” to enable it. The MicVolume can range from 0 (mute) to 255 (full volume).
