"WAV editor (free): Audacity (http://audacity.sourceforge.net)"
If you need/want a free WAV editor you should also look into Encounter2000 (http://www.waschbusch.com/software.asp) I use both Audacity and Encounter; I mainly use Audacity for working with wav files but I use Encounter for final cleanup and optimization (because it can convert and downsample, from 16bit to 8bit for example to shrink the filesize, whereas Audacity can't.)
