I do think this is a great idea, and because they do what they do to make the ads appear louder (this energy thing Brad mentioned), it should be programmatically relatviely easy enough...I think!
Good luck with it,
Dave

Yes, don't get me started how much they crank the volume of commercials
here in the UK.
As it stands the commercial detection code in the UK (CVS as of end
Mar05) basically doesn't work. Maybe the channels in the US dont mix it
up as much as here?
Anyway back to the sound. Yes the average sound levels during the ad
breaks really crank (at least in the UK). To me it appears that all ads
/ promos are run through a compressor, decreasing dynamic range and
increasing the average energy much much higher that the shows. This
combined with statistical analysis ... eg commercials run 3-4 mins, four
or six breaks an hour, I would have thought this would work.
I can't code to save myself, but I can and will have a look at the
average levels of a statistically significant number of shows to see if
it is obvious.
Stay tuned
Best
Steve
