I agree with Ted that Audacity’s Noise Reduction can be very effective. I have
found that it does a better job than the tools provided with Reaper. As Portia
mentioned, applying this sort of effect can introduce unwanted artefacts to the
audio. To the extent that this happens will depend on the character of the
offending noise, together with the type of sound being recorded. It can result
in a flanging effect on the recording and it can be a trade off between the
amount of reduction and the adverse effect on the recording.
And despite what you might read on the internet, Jacob’s summary of how to do
it is correct. First get a sample of the offending noise and then apply noise
reduction.

I started using gold wave and now I use audacity almost exclusively. I,
personally, I think that the noise reduction tool in audacity is actually
superior to gold wave.

I know you already succeeded, but thought I'd throw this out there.
Keep in mind, noise reduction also can muffle or even drown out the
voice completely. There are some plugins that supposedly hardly do
this, if at all, but those tend to cost money, at least from my
experience.
So while a lot of podcast and voiceover gurus say that the noise
reduction in Audacity isn't great, I hope, at least, that it can meet
your needs to a degree.

Awesome, thanks a lot! A couple things I read online said not to do it this
way, but it actually did work fine, so I appreciate it. I ran noise
reduction three times using different selections of silence. Not sure the
third one did anything, but the first and second both made it way better.
Much appreciated.

While track is playing, use the [ and then ] keys to start and end selection
on a part of the track that just has the white noise in it, then hit space
bar to pause playback, activate effects menu, hit enter on noise reduction
and activate the get noise profile button - it will be best if you can
select something like at least 2 seconds of the sound, with nothing else
being heard - then select the whole track using ctrl + A, and, reactivate
noise reduction off the effects menu, and now activate OK button, and, it
should try to remove ssounds/noises that match the signature it derived
earlier.

Hi all,
I’m a very new Audacity user with JAWS trying to reduce noise in the
background of a speaking track on a podcast. It’s noise from an appliance or
something (track was recorded in a kitchen) that makes a soft noise that
sounds like wind whistling consistently throughout the track.
I checked David’s Audacity guide (which is unbelievably helpful), and there
isn’t anything on noise reduction in there. Any thoughts on how to do this
with a screen reader? The guides for sighted people I found are quite
unhelpful.
Thanks,
Sy
