I've never been here before, followed a link.

I'm a regular reader of moorewatch.com, and I've been hearing about this thing for some time. I've worked in broadcast TV for over 30 years, and I know that it's common in live situations to include a little thing called "AGC" (Automatic Gain Control) in the signal path, to maintain a more-or-less consisitent (if not absolutely constant) level output. As there is no industry standard for the degree of AGC employed, it's quite possible (and it could be checked) that if either or both CNN and ABC were using it, they set their AGC's differently. Furthermore, the degree to which sound emanating from any particular location in the hall were picked up by the various microphones would depend upon where they were aimed.

So while it may be possible to demonstrate differences in the booing levels between the CNN and ABC broadcasts, there are sufficient incidental sources for such differences to invalidate the conclusion that the staff of either one intentionally spiked the booing level for any reason.

I don't think anybody cares but UberMike anyway.
