Question A/C compressor/clutch loud buzzing

My daughter's 96 Jeep Cherokee has a very loud buzzing type of sound comming from the A/C compresssor. It's not a really high pitched squeel type of noise, but is not a metal to metal type grind either.
The noise changes pitch with the speed of the engine. Turning the A/C on makes the noise dissapear. A/C blows cold, so I don't believe it's a servicing problem

My question is if anyone knows if this may be caused by just the compressor clutch, or the compressor itself. Or something different completely?

sounds like the clutch check the front clutch plate to see if its broken or has an inncorect gap sounds as if the front clutch plate isnt disengaging all the way when a/c is off.
