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

Subject: [audacity4blind] Noise removal difficulties
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*
