Well established in the consumer electronics industry, Digital Audio Signal Processing (DASP) techniques are used in audio CD, computer music and DAT components. In addition the applications afforded by this versatile technology now range from real-time signal processing to room simulation. Grounding the theoretical foundations of DASP in terms of practical applications, this book gives meaning to the mathematical concepts behind this subject area. It includes detailed accounts of: AD/DA conversion and DSP systems Digital Transmission Systems and M-PEG audio coding Studio technology and electronic storage media Audio algorithms: equalization, dynamic range control, room simulation and sampling rate conversion For Audio and Communications Engineers this book provides a thorough coverage of the technical basis of DASP. For Research Students in Signal Processing or Applied Physics it transforms erudite audio signal processing theory into tangible concepts.
