filter

Whenever I record with my microphone, I get this constant beep sound on the background. It appears only when I turn volume up, so it is not very loud, but its noticable and pretty annoying.

Because it is constant sound, I thought it should be possible to filter just that one frequency, but I have absolutely no idea how to do it.
