Comment Ad Agencies are responsible, not the TV stations (Score 2, Interesting) 636
The problem is commercials are mixed with LOTS of compression (which limits the dynamic range) and recorded to the master tape at the maximum level it can handle. Movies and TV shows are mixed with a lot more dynamic range to allow for example, a gunshot to sound louder than a voice.
If the TV stations consistently lowered the level of commercials when they transferred them into their systems (by 3-6db), then they would sit better after programs and wouldn't send us all grabbing for the remote to mute them. It's not going to stop me from muting them, but then I hardly ever watch TV as I find it mind numbingly boring and retarded.
Also in response to some sort of volume limiter that kicks in when the level gets loud, its only going to ruin your movie soundtrack and make those huge explosions small... so IMHO its a bad idea.
My idea was to scan the picture for the TV station ID which they impose over the programs but not commercials and detect which is which by this method or link the TV to a internet based service which can tell you when commercials are playing on your channel and auto-mute and dim the picture. Probably people would pay for a service like this.
