    How much quality do you lose when coverting from MP3 format to CD format? Most MP3s came more CD format originally so you are actually converting the file a 2nd time to get it back to CD format right?

    In MP3's you always lose something because of the "lossy" compression algorithms used. There are different kinds of mp3 compressors that throw away different portions of the original sound wave so that there are more repeatable 0's and 1's to compress and to describe it by saying that there are "30 0's" and "50 1's" which is shorter than writing "000000000000000000000000000000" and "11111111111111111111111111111111111111111111111111 " (that's a bit crude and maybe not entirely accurate, but it makes my point).

    If you've ever seen an mp3 in a wave editor compared to the original wave file of a song ripped from a CD uncompressed, and viewed it in spectral view, you see a much different image of the same song. Some mp3 compressors throw away almost all the high frequencies above a certain point. That file will not sound nearly as bright as the original CD. Other compressors do a better job of hiding what was done.

    An mp3 is not like a zip file. Once it's gone it's gone. Converting an mp3 back to a wave file to make a regular CD does not give you the same file as the original that the mp3 was made from. The file size may be back up to full wave file size, but that's because wav files (and original CD audio tracks) use a fixed number of bytes per second no matter what the material is - even if it's silence.

    That happens to be a reason I don't like mp3's and won't work with them. I don't like the idea of losing something in the process. That's just a personal feeling. YMMV.

    Thanks for replies fellas. That's exactly what I was wondering so that means if I found a MP3 that I really like, the only way to hear it in its true splendor would be to buy the CD right?
