Does anyone have any suggestion on removing or reducing the background noise in video recordings? Whenever I use my digital camera to shoot quick videos, I get this sound (probably because the microphone is hyper sensitive and so it picks up lot of unwanted noise) in the background. I am sure there should be some way to get rid of such sounds...

Forgot to mention, I am looking for a PC based solution. – Alok Nov 27 '09 at 21:32
Do you want to get rid of ALL sound, or selectively edit? – DaveParillo Nov 28 '09 at 1:34
I want to delete the background noise, for example imagine you shot a video next to a waterfall and there is this constant noise (for the purposes of your video) of water in the background. I was wondering if there is some way to reduce or eliminate such background noises. – Alok Nov 28 '09 at 4:57

I use Apple's Final Cut Pro Studio and Soundtrack Pro. Here's a great tutorial on how to do it: Surgical Noise removal.

Since you're a Windows user, I can't help you as much with audio editing. Most audio programs, including Audacity, include noise gates though, so you can use it for something. Unfortunately, surgical removal is relatively unique.

If you really cannot deal with that, buy Pro Tools. I hate it, but it has what you're looking for.

This is for the PC - I think the best program for editing audio is Adobe Audition.

There are so many different approaches to removing unwanted noise. A few easy filters you can apply without too much trouble are the Noise Reduction Category under the Effects Tab. There you have:

Basically, you find your noise floor and or you selectively profile the noise and then apply the filter. You can preview first, in order to see what it sounds like. I believe if the noise is -45 dB or below then you may have a serious problem, which means it may cost more to get rid of than its worth.

If you're looking for more advanced techniques, we can show you but it takes time, the manual and some training - remember this is more of an art, than a science - Good luck!
