Microphone buzz sound help

[petroley]

I need your help guys. My mic start to produce some very weird sound (something like a bee traped inside mic case). I`m wondering is that really mic or the sound card problem??

My mic is CAD Audio - GXL3000BP Multi-pattern Condenser Microphone

thank you

Is it constant/ intermittant?
Does it sound like somethings broken off inside the head basket?
Does it sound like its electrical?
Has it been exposed to damp?
Has it been exposed to high spl?

I havent got a clue whats going on with it and i doubt i'd be able to help but i think this may help someone else more knowledgable than me help you.
I'm ok with using mics but i'm no repairman. Unless its simple then i can manage.
If you have no experiance with mending mics i suggest you take it to a reputable repair shop.
Someone here may still be able to point you in the right direction. Where in the world are you? I ask as it will also help.
good luck
