The last statement is meaningless. The sample rate of CD is nominally 44.1 kHz, but the rate during playback, as many have said, is determined by the accuracy of the quartz crystal oscillator in the player itself. Most crystals are accurate to a fraction of a percent, but it wouldn't surprise me that some rock-bottom cheapo players might be off a lot more than more expensive ones. In any case, the phrase "accurate to 1/44100 of a second" doesn't mean anything. -- Rich Fanning {sun,ucbcad,uunet}island!rich
