Someone over on Piano World (PW) posted this link to FULL FREE versions of several older Adobe 32 bit products (but read the disclaimer):

I highly recommend Adobe Audition. It started life as CoolEdit, arguably the best multi-track audio recording and editing shareware in the world at the time, and was bought out by evil Adobe who sold it for something crazy like $500 a pop (why is Adobe pricing is always so sky high?). Adobe tinkered with it, first making it a little better (v1.5) then quite a bit better (v3.0 you can download from the link) then they gutted it like a fish (later CS versions).
Anyway, I've done audio restoration with it; recorded, mixed, and mastered a friend's CD with it; and it's a key tool for the technical sound analysis I do for my digital piano reviews over on PW.
There's a disclaimer on the page that wasn't there when I last visited, so let your conscience be your guide. Adobe isn't being less evil or anything by doing this, they retired an old license server and left a bunch of folks hanging, and this was the solution. Here's an article on it.
