"Wouldn't it be a good idea if the car radio/CD player's volume increased as the car's speed increased, thus helping overcome the increased road and wind noise?" Thus ran conversation between some mates many years back. And - oh joy! - they do that feature now.

It's rubbish. I switch it off. For, I suppose, the same reasons as most of the above posts dislike compression.

(btw, I sent Treewind an early home recording made on my new (second hand via e-Bay) digital multi-tracker a year or so back. His constructive observation was "Too much compression!!!" I'd lazilly used one of the out of the box mastering programmes. He was right: the results are much better with little or no compression.)
