you know they deliberately do that...commericiasl have a different volume level when compared to a t.v program...sons of bitches...ocd...we all have a short comings and anyone who claims otherwise obviousily has the biggest short coming of them all...self dellusion.
They aren't actually louder, they have just been compressed to reduce the peak-to-average ratio which makes them seem louder (ie most programs have some peaks--commercials are compressed to comprise largely of peaks--thus on average they seem louder--the loudness is actually regulated by law). More geeky sound info . . . ..
OCD, eh? Going to venture into the fun world of medication?
