After ten years of Digital Audio, a review of its achievements and directions is appropriate. The pros and cons of today's digital audio parameters (sampling frequency, word length, others) for present and future use are discussed in terms of digital recording, digital processing, and the manufacturing of high-quality final recordings. The impact of high-performance DSP on digital audio sound quality is examined, and some new challenges are identified.

This paper was very significant when it came out because it was presented to an audience of people who were still just becoming familiar with the downside of digital recording back in 1990, and it showed specifically many of the problems of digital systems in that era and what needed to be done in order to fix them.  For much of the audience it was a very eye-opening experience because so many people at the time were convinced that the new generation of digital systems was "perfect" and then along comes this guy from Studer... err.. Sony.... demonstrating zipper noise on faders and showing the math that generated it and how it could be fixed.

Even Stereophile devoted a long essay in their December 1990 issue summarizing this paper.  It helped to change the industry and to make digital recording what it is today.
