Removing background noise from recordings

[Rokins]

In all of my recordings, you can always hear that background "hissing" sound no matter what I do. Is there any way to get rid of that?

Where would that sound be from? your game or your mic or what?
If it is your mic, you need a better noise canceling mic. Might be a fan in your room or something if that is the case.

If you have multiple input volumes, one of them may be up way too high. You would need to balance them out.

Hmm, ill check that. What about a good noise canceling mic? Know of one?

As someone who does a crapload of Cisco screencap videos (http://www.youtube.com/user/routergods), I've dealt with this before.

What mic are you using? Does it plug into the audio port or is it usb?

On my 20 or so videos, I moved from a audio port headset/boom mic to a Zoom H4 connected to the pc with USB. After going through a bunch of forums, I found the most common cause of background hiss was actually from the audio port as it has high system noise (every change in voltage will give a corresponding change in audio volume). Once you move to USB and a quality mic, the noise will be gone.

It just depends on how much you want to spend. It can get pretty crazy too... audio has a lot in common with boxing, you can spending insane $$$$ quite easily.

Im currently using a mic thats only gaming headset and that goes into the audio jack. I do however have the g110 keyboard that has its own headset jack that then goes into a usb connection, would that work?

Edit: just tried it out and theres no more background noise =]. I didnt do this before because when I switched from the front ports to the back ports in the past, I noticed that the back ports arent as loud as the front ones and I didnt want to lose any sound. I was afraid the same would result if I switched to the keyboard inputs. However, I do not think that there is that big of a difference at the moment. I will check and see though.

If you want no background system noise, you'll have to switch to a USB headset or an XLR mic.... but it could be overkill for your needs.
