Joe Bob User's friend in Google Korea obviously doesn't know that Ogg
Vorbis isn't a codec :)

"Ogg" is the container format, in much the same way as AVI, MPG, MOV or
MP4. The audio stream contained in the Ogg container is encoded using the
Vorbis codec. Thus, a ".ogg" file can in fact be a movie with a vorbis audio
stream and a theora video stream.

Back to the main question, though, about what the best lossless audio
format is for conversion to codec-du-jour as said codec-du-jour evolves
over time. How about audio CD? Okay, it means ripping stuff off the CDs
again next time round, but how often does this happen?

Your average music CD contains something like 600 megs of audio data.
Assuming you have a collection of 300 of the things, that's 180 gigs of
data, which is well within the capacity of a hard disk today, meaning that
storage of your CDs as .wav files is technically possible. However, how do
you know that your HD won't fail between now and next time you need to
re-encode your audio stuff? Will .wav still be supported then? Will your
HD's interface for that matter?
