I remember back in the days driving through the region I would turn on Q-102 and everything sounded much faster! And it wasn't just increasing the pitch...the octave went up with it! That was the only station I knew of where every aspect was speeded up, not just time compressing a track where it would sound like the original but sped a notch to save those 24 seconds.
Q did speed the pitch on the turntable or CD Player by +3%. They did have plenty of equipment that could have corrected the pitch/tempo, but did not use it for that. They did it for the reason stated above, to make the other stations sound boring (Eagle 106, Power 99).. at the time they were not all owned by Clear Channel... it is common practice in CHR to speed music, I don't know if it's common to speed by +3 or not, but that's what they did...
