And, for once, it should be enforced
I've spent the last six months sat next to a DSP engineer who was writing code to measure the average[1] levels on transmissions and adjust the gain to ensure the ads aren't too loud.
Sometimes, encoder manufacturers get things right.

[1] "Average" is actually quote hard to define; each advert is a separate item, and the repeats between adverts are their own thing. But the overall result of Huw's work seems to be a good thing.
