1. Brief description and aims of module:

This module engages you with the understanding of 'sound as signals'. The properties of sound in acoustic, mechanical, and digital signal forms are investigated. This in turn allows you to explore theoretical and practical ways that enable you to engage creatively and systematically with sounds. The module proposes a phenomenological approach that looks at the objective properties of sounds and at how they are perceived by the listener.

This module aims to enable you to:

• Develop an in depth knowledge of the representation and manipulation of sound

• Equip yourself with knowledge of digital synthesis, processing techniques and methods relevant to creative sound practice

• Implement and creatively employ audio processing algorithms

2.Outline syllabus

The module investigates the following areas:

• Sound as an acoustic and mechanical phenomenon, and its digital representations

• The sampling theorem

• The sinusoid

• Delay lines

• Feedforward and feedback filters

• Textbook audio processing algorithms (e.g. “pitch shifter”)

• Auditory perception; limits and thresholds of perception; auditory illusions and perceptual data reduction

• Basic physical computing

• Elements of algorithmic composition

3.Teaching and learning activities

Lead lectures will introduce theoretical and practical content, whilst workshops and guided laboratory sessions allow you to experiment in the creation and implementation of audio design. Seminars allow you to share and discuss your work with your peers.
