WMA 64 Kbps converting to WAV. or higher WMA settings?

A friend of mine ripped this disc for me a long time back, the other day i was browsing through it`s properties and unfortunately was dissappointed to find that it had been ripped in WMA 64Kbps. I`m aware that Wma is a good format but not with the level of 64kbps, because i`m the type of person that believes only in WAV. when ripping audio to my pc.I`m curious if there is any way i could regain audio quality maybe encoding this album to wav. or maybe higher WMA settings. If not! then is there any program out there that could actually do this or is it the old clic that no audio quality can be re-stored once a file has undergone a compression of some sort? Thanks for any help!!!
