Yes, don't get me started how much they crank the volume of commercials here in the UK.And it might also be worth looking not just at the lulls but in sudden changes in the mean energy.
The rules prohibit commercials from actually being louder than the show, but that's the peak they measure. The show uses the peak only for loud things, like explosions, but the commercial tries to get as close to it as it can. At least some do.
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 _______________________________________________ mythtv-users mailing list [email protected] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
