Wierd noise with compressor when reving motor?

[White-V-6-S-Ten]

I have an 03 with the 4.3 and when the ac is on and i rev it to a cretain point it makes some odd noise, It does go away if i let off the gas and it goes under a certain rpm or if its making the noise and i turn the ac off it goes away... I dont know what the deal is but the ac is still nice and cold
any ideas would be great thanks!

Are you revving at WOT or just a few 1/2 burps of the throttle? Compressor clutch is designed to release during WOT. Does your clutch make noise when its engaging/disengaging?

like say when i am driving along and go to pass someone and get on it it will make some noise like its bypassing thats what i have thought but it seems to be doing it more often i dont know how to explain what it sounds like it really bothers me
lol!
