You can listen to this podcast to know how the noise removal word. This isn't podcast for blind user, but I think you could understand by listening to the demo. This also have some tips to reduce noise before recording.

Hi Sharni!

To use Noise Removal you must first select a fraction of the track containing only the noise you want to remove. Then call Noise Removal and press g for Get Noise Profile. Only then should you select the whole track and apply the effect. The first control, Noise Reduction dB, is the value by which the target noise is reduced. Increasing that value may produce better results up to a point.

Can you describe the noise you're getting? Is it a hum or a buzz or more of a hiss? If it's a hum, try shutting everything down that's anywhere near your computer. A phone or an amp or a badly insulated cable may produce a hum. Sometimes it can also help to just use a different socket.

Good luck! Robbie

I recently went to the control panel to disable all enhancements for recording. Now my voice is sounding more normal, but I have a horrendous continuous background noise that I'm assuming is generated by the computer itself, even though I'm using a microphone on my headset rather than the inbuilt one. I tried the noise removal effect, but I was having trouble setting the parameters. I'm considering trying the Notch filter, but that also sounds rather fiddly and I don't want to muddle through the process and get frustrated with it. I can't afford to get better hardware right now, so I could use any tips you may have. I've tried turning off my electric fan (which is a constant presence in my room), shutting my door and everything, but the hum is still there and I don't know how to get rid of it without turning my voice right down as well. I tried and then amplified it, but that just made the noise loud again. *pouts*
