The "help" files are excellent in Cool Edit (heck, even the

'96 version was well-written, with an excellent interface,

great help files, and it is STABLE!). Once you set

parameters, the program "remembers" them, and you can

also save the fft "noise-profile" for your camera - so,

essentially, all you need to do is import the WAV file,

select "noise reduction", hit "go", and save the result...

BTW, I often export the whole video timeline and process

the whole thing in Cool Edit, if the noise type is constant

throughout (though it is easy to select portions of the

file for processing...).
