At Robbie: I checked the manual before attempting it to see what I had to do. I
made sure I got a noise profile, but even so, it still turned down both the
noise and my voice. It's a noticeable hum that sounds just a bit like an
amplifier that isn't plugged into anything, but not quite as grating. I do have
a speaker system that's both not plugged into my computer and turned off at the
switch on the device itself, but not unplugged from the power-board behind my
computer. Could that be it?
At Cuong: I don't have an ipod, so I can't listen to that podcast. Thanks for
taking the time to help me out, though.

Hi
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

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*
