Nero Wave Editor is quite good - especially for noise reduction. I find it a bit 'clunky' for copy/pasting, though. Not quite as bad as CoolEdit/Adobe Audition in that respect...!

Everyone finds something that suits their needs - a bit like photo editors - and nothing else feels comfortable. Sometimes you need to use different programmes for their different features, too.

It was expensive, but I prefer SoundForge (I'm on v8 now). I can have the job done (check out Ali O'Brien's Sounds of Folk on Radio Britfolk - programme 20 online on Monday) in the time it takes to think about how the others work!
