Eh look, you need access to a Windows machine, that's all there is to it, or perhaps a Windows emulator for Linux if one such exists (I believe it does for Apple)... There is no Linux version of the APE decompressor for the redbook audio files as far as I know, if there is, it's not available from the author's site. So, either get to a Windows machine or find out if there's some virtual PC emulator that'll let you run a Windows OS instance on your Linux OS...
