We begin with a January 1993 article from Robert Harley called <A HREF="http://www.stereophile.com/reference/193jitter">The Jitter Game</A>. RH explains, "Clock jitter is a serious and underestimated source of sonic degradation in digital audio. Only recently has jitter begun to get the attention it deserves, both by high-end designers and audio academics."

When I first started buying records at the end of the 1950s, I had this vision of the typical recording engineer: A sound wizard wearing a white lab coat rather than a cloak festooned with Zodiacal symbols. He (it was always a "he," of course) would spare no effort, no expense to create a disc (LPs and 45s were all we had) that offered the highest possible sound quality. At that time I also believed that Elvis going into the Army meant the end of rock'n'roll, that my teachers knew everything, that politicians were honest, that socialism was the best form of government, and that talent and hard work were all you needed to be a success. Those ideas crashed and burned as I grew up, of course, but other than the long-discarded white coats, each new record I bought strengthened rather than weakened my image of the recording engineer.

"Desperation is the Mother of Invention." Isn't that how the proverb goes? Certainly it applied ten years ago in the case of the Philips engineers working on the development of the Compact Disc system. Given a specification that had included a 14-bit data word length, they had duly developed a 14-bit DAC chip, the TDA1540, only then to be informed that the CD standard decided upon after Sony joined forces with the Dutch company would involve 16-bit data words. (Thank goodness!)
