T9 - Dither and Noise Shaping in Digital Audio: Hows and Whys

Presenter:
Duane Wise, Wholegrain Digital Systems LLC - Boulder, CO, USA

Abstract:
This tutorial investigates finite-word-length in digital audio: how it differs from analog audio, the side-effects of signal quantization, and how the adverse effects of quantization can be diminished via dither and/or noise shaping. The tutorial presents the theory of quantization along with a live interactive audio demonstration that illustrates the motivation behind the theory.
