Are you looking for the absolute best, in which case you're looking at pro-tools, adobe audition or soemthing of that ilk (and spending hundreds on it)?
If you're looking for free then you could try something like wavepad, I've not used it myself but it seems pretty popular.

You also get simple wave editors with Nero and most cd-burning packages.
