DESC9115 - Digital Audio Systems
Faculty of Architecture, Design and Planning - 6 credit points
HECS Band two
EFTSL: 0.125000000
Help? - Unit of Study Costs
Department: Architecture Faculty
Offered session(s): 1
Teacher/Coordinator: Assoc Prof William Martens

Classes: Lectures 13 x 1.5 hrs, Labs 13 x 1.5 hrs

Assessment: Three assignments (70%); Three laboratory reports (30%).

Practical work: Practical exercises include programming for digital signal processing of audio signals using high-level software packages to generate, manipulate and analyse sounds.

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: digital principles, digital systems, sampling and quantisation, 1-bit and multi-bit conversion, digital signal processing, filtering, spectral analysis, sampling-rate conversion, data compression (MPEG etc), effects processing (echo, reverb etc), virtual reality audio, mixing, editing, optical storage (CD and DVD), magnetic storage (DAT and disks) and transmission formats (AES/EBU, SPDIF etc).
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.Permission required unless enrolled in the Audio stream. Enrolment numbers are limited by teaching resources.
