Tuesday, May 23, 09:00 — 11:00T17 - QUANTIZATION EFFECTS IN AUDIO SIGNAL PROCESSING
Presenter:
Jamie Angus, University of Salford - UK
Abstract:
In this tutorial we will first present the principles of quantization and the basic effects of finite precision in digital filter implementations (both fixed and floating point) on the audio signal. We explain the effects of finite precision on frequency response (using an audio equalization task as an example). We shall see how different forms of filter structures offer advantages when finite wordlength is considered. We shall also look at how different structures affect the audio signal. Finally we will discuss the effect of different types of dither and the various pitfalls that can occur.
