i don't see why you'd want to (if the quality is low like the common rm file) but you can do it with only the early versions of streambox ripper. the newer versions don't have it
I have version 2.009 and it converts fine... As far as quality goes, you can clean it up slightly with the e.q. Its not bad on cleaning up mp3s either. I remastered the old makaveli shit and it made a better copy in the end.. Get StreamBox Ripper for sure.... Str8MrE™
