It depends on the format. If you rip a 650 MB CD to a .wav or .aiff format you use 650 MB or a little more depending on the format overhead; they perform no compression at all. Using FLAC or ALAC (Apple Lossless), you can get 50% or better compression of the file, depending on the music, at the cost of considerable time spent ripping the CDs. Both are akin to .zip files, in that they do lossless compression. -- Bruce Johnson University of Arizona College of Pharmacy Information Technology Group Institutions do not have opinions, merely customs -- -- You received this message because you are a member of the iMac Group, a group for those using Apple iMacs and eMacs.
