I presume you mean 'WavePak' (Google gives no hits for 'WvavePak').

This site is among several which say it's freeware (as opposed to 'free
download', which usually means eventually pay-for shareware).

As there are lots of places where it can be downloaded from, it's almost
certainly OK. But if in doubt, ask in the alt.comp.freeware newsgroup.
And if it's not freeware, you will certainly be told!

Thanks for that suggestion. I will ask there. I'm not worried about it
being free or not. It's just that I am a bit paranoid about free/
shareware. A lot of them contain some kind of malware.
