My wife recently got XM radio for her car. We started out listening to the more current music, but eventually gravitated to the channels that ran the '70s songs.

I've noticed that her radio sounds consistently worse than music played on my car's CD player. The middle range seems to be very weak, and there's no detail to the sound.

What's interesting is that she's got a "boost" button that hypes the bass and high end. For more contemporary sounds, it works well. But for older music, it makes the middle register recede even more.

So it seems that the psychoacoustic model that XM Radio uses is based on assumptions of more contemporary music, not the more "classic" music.

Vocal control, you say. Never heard of it. Is that some kind of ProTools thing?
