A Linux command line program designed to "rip" digital audio CD's to wav files, which then can be converted to mp3 or Ogg Vorbis formats via an encoder such as bladeenc or oggenc. The "paranoia" angle relates to the extremely thorough error checking used by the program.

I have ripped extremely scratched, unplayable CD's using cdparanoia; the program is quite amazing. A heavily damaged CD can take a while, however. Since Copy Protected CD's typically mimic a damaged CD, cdparanoia can rip these without difficulty.
