Let me try to explain again - S-H is precisely applicable to vinyl. It is a theorem which tells you the information capacity of a *continuous-time analog communications channel subject to Gaussian noise*, such as a vinyl record. > > If you wanted to use the vinyl medium to store digital data, and to > maximise that data storage capacity... Again, I have no idea what you mean by digital data. Do you mean something like recording a series of clicks on vinyl, in a code that represents sound? No matter what form you use, S-H tells you how much information you can possibly store. As I said before, it doesn't tell you *which* method is best, only what's the best attainable. It sounds as though you are confused about what is meant by capacity. Information is not digital or analogue - it has an intrinsic meaning outside of the medium used to represent it. In fact it has a deep connection to entropy in statistical mechanics, where again you have a pure number which can be defined extremely generally, regardless of the specific system in question. This was perhaps the crucial insight that lead to the entire field of information theory. -- opaqueice ------------------------------------------------------------------------ opaqueice's Profile: http://forums.slimdevices.com/member.php?userid=4234 View this thread: http://forums.slimdevices.com/showthread.php?t=34379 _______________________________________________ audiophiles mailing list [EMAIL PROTECTED] http://lists.slimdevices.com/lists/listinfo/audiophiles
