Listen to the clip, there's a slight rrrrrrrrrrrrrrrrrrrrrrrrring noise in the background and near the end my mic sort of.. cracks? I suppose.

Anyone any idea what's wrong with it?

Do you have mic boost on?

[Niall!]

Nope I don't.

Also; there seems to be a slight buzzing noise when I move my mouse. I mean it records a buzzing noise.
