Maybe you wanna check out Freerip 2.7?
I don't know much about this new version 2.7, but the older versions were ad/spyware free. Only thing was that they had a display for links to sponsors: Amazon.com and one other one. Those are totally harmless and are not really adware at all, rather just stationary built-in links, which won't bother at all. Very compact (1.2 MB) and easy to use.
edit: This program makes both wav and mp3 files.
