I need to remove all audio below a certain db.

Similar to "Voice Detection" located within common voice chat programs such as "Teamspeak", I need to remove audio below a certain level.

Essentially I am attempting to record a commentary but am being stopped by constant clicking, and key presses within the audio.

If someone can assist me in removing these I would be extremely thankful.

Sincerely, Bitwah

There is a Noise Gate tool and I think it's a separate install to Audacity 1.3. I need to check.

The chances of it doing what you want is almost zero, however. It is worth a shot. Voice isn't a thing you can easily manage. It's like accurately and surgically separating a patch of grass from within a much larger patch of different grass. There's no discernible place where one stops an the other starts.

Typical problems are clipping leading or trailing portions of words or, if you get that right, each word has little noise tails or you get little bumps of noise here and there. It's not trivial.

I need to drop out for a second. Try Google Audacity Noise Gate. I'll be back shortly.
