So I've got a sample that has a high pitched beep captured from the recorder it was recording with. Quite annoying. I do need to remove it to make the sound more authentic. Any advice on doing this?

If the sound is audible on its own you can grab a copy of it and use that to do a FFT noise filter....

will run in demo mode so that you can process sounds

Effect > Filter > Noise Reduction

or ... you could upload it and ask for people to clean it for you

I have luck with Cool Edit 96 noise reduction. You can keep the noise or eliminate the noise to some degree. You can still find the file out there and the serial too, Syntrillium is now Adobe so it's not supported anymore but does great things.

Also, there is a vst effect called sniper, I believe, it is an extreme EQ that can filter out entire bands of the audio spectrum completely and let you zero in on specific frequencies.

I would definitely go with Cool Edit also. I don't know if I'd suggest something as primitive as Cool Edit 96, but I'm sure it should all work as decently as any of them. I use CEP 2.0. Highlight your beep, go to Noise Reduction - Noise Reduction. Get Profile From Selection, then hit Close. Go back to your waveform, highlight the entire thing, go to Noise Reduction again and click OK. You can also change your reduction level but you can messa round with that.
