MOD files consist of individual instrument samples (small WAV files), along with when to play which instruments, at what frequency, and with what special effects. This allows an extensive musical score to be made of a small number of samples, reducing size. CD audio is a continuous stream of digital frequencies, basically one huge sample. To convert from CD to MOD, then, requires advanced AI to separate the sound into individual notes, individual instruments, and their pitch. This kind of conversion cannot be done automatically with the current level of technology (as far as I know), so making MOD compositions remains an art for human techno-musicians. It would be possible to create a file in valid MOD format from a CD, but it would be very large (basically putting the whole song into one instrument and saying to play a single note) and defeat the purpose of the MOD format. If you are interested in CD quality digital audio, look at MP3 at http://www.mp3.com or the new upcoming VQF at http://www.vqf.com. Unfortunately these are both lossy compression formats, so you lose some sound quality, and they have software patents, so it is hard to find free encoders. K-jofol is a free MP3 and VQF player for Win32 that is being ported to Linux soon. David Manifold
