The broadcaster could program the commercials to not exceed the average level of the program. And yes, they are following the letter of the law...but the end result is that the commercials are blaring. Which is why the law is about to be changed.The problem with that is that the broadcaster doesn't change the audio levels constantly during broadcasting. Especially for television. It's set at a constant level, and the processing equipment keeps the peaks at a certain level.
There's no guy in a control room saying "OK, here come the commercials...crank it NOW".
This stuff is all automated now man. The computer doesn't care about the content of what is going on the air, all it cares about is the peak levels being sent out and keeping it below a certain level to prevent over-modulation. Doesn't matter if it's Law and Order or Crazy Sams Sunglass Emporium. The advertisers use the dynamic range processing to bring ALL the audio up to the peak levels and keep it there. And the system on the broadcast end doesn't care as long as none of it is going over the peak levels. Doesn't matter how often its getting to the peaks, as long as none of it goes over.
I gotta run, but next weekend when I'm at the station, and if this thread is going on, I'll post a couple of audio examples of a non-compressed song (what you normally would hear on a CD) and a compressed song (what you would hear on a commercial if the song was used as part of the ad).
See ya next week.
Again, that's just a weak excuse for what the broadcasters CHOOSE to do.
They clearly have engineers while their stations are up and running. It would be a simple enough task to check the levels and turn the shit down. They could PROGRAM their equipment to do that automatically if they had a mind to be civil in fact. And they could do a check on the volume of an advertisement when they screen it for impermissible content (they do have to do that to make sure some dopey ad guys haven't inserted nudity into a commercial for example). They could declinee ads which violate their policies in that regard. They could issue guidleines and standards to the ad compmanies informing the latter that they will not accept ads that blast the eardrums of their customers.... Their warnings can be written in geek-speak, but hte gist of it could be simple and clear. They do none of that. It's their fault.
Yer not understanding me...
It IS programmed to do that. Audio levels not to exceed XXXXdB. What yer experiencing is ALL the audio levels of a commercial at XXXXdB. The commercials are following the "letter of the law" so to speak, it just seems that they are louder. And it is purposefully done that way through compression of the audio commercial.
