For the record, KVIL ... NEVER ... had lots of compression, especially during the so-called "heyday" late 70's - early 90's era. There was usually a "slight" touch of reverb but even that was gone by the late 80's. Until well into the 80's, KVIL didn't even use a mic processor and very little compression.
Ron found a study that showed the female ear has different qualitites than the male ear and that the female ear was more receptive of harsh, high pitch sounds, deep bass and fatigue. The study also showed that a typical female listener would turn away from a station when they heard these things more often than not because it was essentially painful to their ear. For this reason, by design, during those times KVIL did everything possible to eliminate those sounds - including editing songs generously when deemed necessary.
I do recall one day in 1979 when KVIL tried out a new audio processor when we were still in the old Park Cities Bank building in downtown Highland Park. For ONE DAY it sounded like Z-97, V E R Y processed and LOUD...everyone HATED it and that processor went back to the manufacturer after that one day... Other than that, KVIL ran minimum processing for many years.
Just .. for the record from someone who was actually there.
