I just worked out that this is my exact problem. I'll record on battery power
from now on. I'll take my other precautions as well--I can actually hear my fan
in the background and it's more obvious with the humming gone, but at least I
know how to fix that easily enough. :)

Hi
Do you use laptop to record? I think I used to have
the same problem to you when I use my laptop, and plug the power. I solved this
by record audio using laptop with battery only.
For the audio, you can go to the given link, and
download the mp3 file. Don't need an ipod, or something like that.

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!

[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.
