Stations operate under strict guidelines for maximum output levels, and they also generally need to handle a wide variety of input sources (mics, CDs, LPs, external feeds...). And there's no standard for the loudness of radio material, as far as I can tell. So they've got to do *something* to equalize the loudness of the tracks.FWIW, I have seen the inside of a college radio station, and I believe they use a limiter. The classical station in town (KMFA) almost certainly uses a compressor, based on my listening experiences, but it's pretty mild - the announcer is often louder than the music, but the dynamic range of a lot of the music seems smaller than it should be. The classical station in Dallas also sounds compressed. The NPR station in town has extremely consistent loudness levels between songs...
There's no elf in the back of the studio gainriding the songs. They use a compressor.
