Module summary

On completion of this module students should be able to demonstrate understanding of:-- Loudspeaker design issues (specifically frequency response, cabinets, woofer/tweeter, crossover filters);- DSP (digital signal processing).

Objectives

For the students to understand many of the issues involved in modern sound systems, including loudspeaker design and digital signal processing systems.

Learning outcomes
On completion of this module students should demonstrate an understanding of:-

- Loudspeaker design issues (specifically frequency response, cabinets, woofer/tweeter, crossover filters);
- DSP (digital signal processing).

Skills outcomes
Develops critical judgement of audio quality. Further experience of writing C/C++ programs.

Syllabus

Loudspeakers: woofers, tweeters, cabinets (no acoustic detail), crossover filters.
Techniques for measuring loudspeaker frequency response.
DSP (digital signal processing): simple FIR low-pass filters, abstract algorithms and C/C++ code to implement them, methods of testing them.
Implementation of such a filter, first on a laptop/desktop and then on an embedded processor.
