Audacity is basically a stereo editor which will do multitrack work at a
pinch, and Audition is a system which will let you do a multitrack
project from start to finish. They can all do sample level editing and
digital gain automation, and you can get many plugins to do things the
native programs can't do.
FWIW I use Audacity for declicking recordings from LPs. The two main
suggestions I'd make for this are as follows.
1) Where you can, use the 'repair' effect, not the one labelled
specifically for click removal.
2) Use something like 'sox' to generate a second, filtered version of the
file. I use sox to apply a highpass (2nd order) filter with a turnover at 5
kHz. I then load this below the main file into Audacity. This filtered
version makes many clicks much easier to see. When editing set the main
file to 'solo' and the filtered to 'mute'. When finished, just save the
edited main file.
Loud bangs and clicks are fairly easy to see in an audio editor's wveform
display. But lower-level ones can often be audible without being easy to
spot until you can zoom in to them. Using a filtered file gives you a
better chance to find where to zoom in. :-)
The downside is you need to avoid accidentally adding the clicks back in
when you save the results!
FWIW I've assigned the 'R' key on my systems to apply the 'repair'
function. Speeds things up. But note that for best results you may
initially need to experiment with how wide a timespan to select for a
repair. Once you've got the hang of it, this will become obvious.
