Hi Mike,
Forwarding this to the list where users and developers might be able to assist.
Hope this helps!

Subject: Frequency Space Editors in Linux
Hello Linux Audio,
I just wanted to find out if anyone know of any Linux programs that do sophisticated noise
removal from recordings, like the frequency space editing process of Windows programs,
Adobe Audition or Cool Edit. I wondered if there is a plugin for Audacity that might do
it.
I need to use something other than standard noise sample removal plugins because the
crackle is only present when the music is playing, not present during quiet stretches.
Thanks,
Mike

It depends on what you need to do precisely.
To be clear, the frequency dependant functionality of the noise removal in
the windows programs mentioned, only appeared in Adobe Audition (1.5 I
believe) after Adobe had purchased Cool Edit from Syntrillium(sp?). Before
that Cool Edit had used only a sampling based process. And really their
frequency based process is only a noise reduction process IIRC, meaning you
essentially remove that frequency range for that period of time, I think it
is a bit smarter than that, but the basic concept is there.
Al this being said, if there is a crackle, there are some specific
algorithms that exist that are _not_ the broadband noise reduction that you
seem to be looking for(In other words are specifically for declicking
audio), that may be of more benefit. However in all these areas of
restoration, Linux is sorely lacking. You can try GWC, but I was never
impressed by it or Audacity for restoration work. Sadly if you are
depending on restorative work, your best bet is either to use another
platform at this time, either another OS or via realtime hardware based
solutions like CEDAR if you can afford it. Alternatively you can attempt to
run other plugins/software via WINE on Linux, whcih I have done in the past
with mixed results.
But really to my knowledge there are no good native audio restoration tools
on Linux. I am currently using the WaveARTS MR Suite on OS X for this work
myself, though since it is machine based authorization(not iLok), and
several of their plugins do run on the receptor hardware, it might be
worthwhile to try to run it via ArdourVST/Wine and see if it can be run on
Linux. This is on my TODO list as I slowly progress to Linux again full
time for production work, but is not something i have had time to do yet.

Try Gramofile [1] or Gnome Wave Cleaner [2]. Results will very a lot
depending on the source material. There is a noise removal plugin of
Audacity, but IMHO it's not great, but let your ears judge.
Good luck,
Lorenzo.

Definitely. Ceres started its life on the SGIs sometime after 1990,
with various ports for various platforms following. The ongoing
development of Ceres (and some other things) at NOTAM can be looked up
here:
http://www.notam02.no/web/category/research-and-development/software/?lang=…
Btw, Henrik Sundt at NOTAM has been working for some time with 'swash' -
a program which does lots of spectral-domain work in sounds, amongst
other things removing noise intelligently. It does some really
brilliant work.
Try email him at <hsundt(a)notam02.no> for more info, and perhaps a
version to try out.

At one time I was rather heavily involved in the original Linux ports of
the NoTAM software. I've worked quite a lot with Ceres, Mix, Bio, and
the others linked in Anders' message.
Kjetil's current version of Ceres appears to have consolidated most of
the goodies found in previous ports.
Btw, I've used Ceres for some noise reduction, just getting rid of some
obhvious artifacts. Most of the time I've used it as a sound creation
utility, its Transforms are certainly some of the weirdest I've used. :)
Thanks for the link, Anders, it's nice to see that the older NoTAM stuff
still lives on.
Best,
