I was working on a podcast show mix recently in Pro Tools, the audio software that I use, and couldn't figure out why my voice volume kept dropping. Incidentally, I use a USB mixer to operate the faders and other controls of the software. Then, in walked Elizabeth, my wife, as my frustration was reaching a peak. She said, "What's wrong?" I said, "My voice keeps vanishing just as I take the theme music out, and I can't figure out why!" And my never-has-looked-at-the-software-in-her-life wife then pointed out, "Why is that line on the screen dropping when the volume drops?" That line she spoke of was the automation for the master fader, controlling the volume of everything. I see! I was moving the wrong volume control up and down. A-HA! I have seen the face of Pro Tools tech support, and it is Elizabeth.
