Preface to the First Edition
Digital audio signal processing is employed in recording and storing music and speech signals, for sound mixing and production of digital programs, in digital transmission to broadcast receivers as well as in consumer products like CDs, DATs and PCs. In the latter case, the audio signal is in a digital form all the way from the microphone right up to the loudspeakers, enabling real-time processing with fast digital signal processors.
This book provides the basis of an advanced course in Digital Audio Signal Processing which I have been giving since 1992 at the Technical University Hamburg-Harburg. It is directed at students studying engineering, computer science and physics and also for professionals looking for solutions to problems in audio signal processing like in the fields of studio engineering, consumer electronics and multimedia. The mathematical and theoretical fundamentals of digital audio signal processing systems will be presented and typical applications with an emphasis on realization aspects will be discussed. Prior knowledge of systems theory, digital signal processing and multirate signal processing is taken as a prerequisite.
The book is divided into two parts. The first part (Chapters 1–4) presents a basis for hardware systems used in digital audio signal processing. The second part (Chapters 5–9) discusses algorithms for processing digital audio signals. Chapter 1 describes the course taken by an audio signal from its recording in ...
