Sounds like this might work: http://www.litexmedia.com/wma_workshop
However it sounds limited unless registered for $24.95
Or Audio Grabber is good.. I used to use this: http://www.e-soft.co.uk
"Free download" but the purchase link says $19.95 so I dunno whether it's required. I know I never paid for mine ;) but that was a few years back.
Or you can record your own wave from your sound card, software/sound card permitting.
