TYPICAL JITTER MYTH: I read in a well regarded high-end audiophile magazine that portable players have less jitter because they use flash memory compared to a PC using a rotating magnetic hard drive. The explanation given: Because a hard drive is spinning, it must have jitter, while solid state flash memory does not. Like so many things in high-end audiophile magazines, this has absolutely no basis in fact. Jitter doesn't come from how the digital audio file is stored. It comes from how it was created, how it is sent in real-time (files are not real-time) over interfaces, and how it is re-constructed.
