The objective of this unit is to provide both a strong theoretical understanding of digital audio and practical experience in applying these principles to digital audio systems. This unit offers a systematic approach to understanding digital audio systems. Beginning with basic principles the unit provides a knowledge base for understanding advanced digital audio components, systems and techniques. Examples of everyday audio signals are used and characterised in terms of their temporal and spectral properties. Practical application is emphasised and is supported through laboratory exercises that include programming as well as the use of current hardware and software packages. Topics include: principles of digital signals and systems, sampling and quantisation, convolution, discrete Fourier transform (DFT), z-transform, transfer functions and impulse responses, finite and infinite impulse responses filtering, audio system design, time-variant systems, audio data compression and real-time audio DSP. Having successfully completed this unit the student will have the tools to understand what happens to a digital audio signal when a given process is applied to it; how to best apply this process and how to successfully combine digital audio components.
