Re: [Avid-L2] True peak audio limiter

 

The more important thing is that we have a dynamic range again. Programs used to be so crushed to the max peak that there was literally as little as 2dBFS of actual dynamic range in some of them. That's not mixing, that's squishing noise together. Makes for a lot of listening fatigue as well. On top of that broadcasters had their own OBAN-type auto-levelers set to max out whatever dynamics were left. More listening fatigue and more noise.

A/85 and R128 are very much needed solutions to a problem that wrecked the quality of our work for decades. Besides, they are based on the assumption that you may now use your ears to mix, rather than your VU or PPM. Not leveling for max output on a scale, but leveling for maximum intelligibility, dramatic effect etc. Then make sure that the average level is at the given spec.

If all productions, stations and cable providers would stick to A/85 or R128, then yes, switching channels on your TV should give you the experience that the average dialogue level between channels is the same. That is not to say that if you switch from a thriller movie to a football match, they will be the same level at the time that you switch channels, as these levels are measured across program length, and are about average levels.

so there is some uniformity of the perceived loudness when changing channels.
