Improving Television Audio by Rob Rettberg

“Due to limited dynamic range of television broadcast, it is advisable that components within a mix such as toms, loud instruments like guitars and percussive instrments should be dynamically controlled by compression. It is also advisable that an entire mix be compressed in order to create a punchier overall reduced dynamic range that still feels dynamic after transmitter broadcast. In this way even the smallest speaker in an average television set can handle a fair amount of volume without overloading and distorting. This will also make the average consumer television sound better than it really is (This is caused by the reduced work load on the television speaker.)

Controlling dynamic range at the source when music is performed and mixed creates a smooth signal that does not hit on the broadcast limiter, which subsequently would make the music sound squashed and fairly undesirable. By compressing the mix to your taste you would have a more controlled musical environment allowing control over the texture of the music, as opposed to being subjuct to – and stuck with – a broadcast transmitter just waiting to clamp and squash down on the music.”
