AUDIO ENGINEERING - 2027/8

Module code: TON1031

Module Overview

This module is central to your development as an audio engineer. It covers the fundamental concepts that underpin all professional audio systems, and introduces essential concepts that you will use across a wide range of the other audio modules, as well as throughout any career related to professional audio. 

You will learn the basic principles of measurement of audio signals, and the principles behind the manipulation and transmission of audio in analogue and digital formats, as used in all professional audio practice. The module balances understanding of the underlying theory with application in professional contexts, and the coursework is intended to allow you to put the theory into practice. The module will also develop the academic skills necessary for the rest of the programme, introducing you to independent academic research methods, writing essays on technical topics, and appropriate citation of academic sources.

Assessment Strategy

The assessment strategy is designed to provide you with the opportunity to demonstrate and develop your knowledge and understanding of audio engineering principles. It also is intended to assist you to improve your research and academic writing skills, and understanding of mixing desk design and signal flow. 

Thus, the summative assessment for this module consists of:

  • audio circuits coursework (addresses learning outcomes 2, 3, 12); 
  • systems diagram (addresses learning outcomes 8 - 10); 
  • 2-hour examination - a written paper given under exam conditions (addresses learning outcomes 1-8, 11). 

Formative assessment

Early in the module there will be a formative assessment, partly you help you learn a technical topic, and partly to clarify the standards, styles, and marking scheme used in University teaching. 

In addition, formative feedback will be given to you in tutorials and throughout lecture and practical workshops, and in the form of regular revision questions in lectures. 

Feedback 

Written feedback will be given on the Coursework assignments. You will receive verbal feedback on your practical work throughout the module, particularly in lectures, and in the form of regular revision questions in lectures.

Module aims

  • To develop your understanding of the theory of fundamental aspects of professional audio systems engineering that underpin all recorded sound.
  • To advance your understanding of professional recording operational practice, and the theory and operation of a wide range of professional audio equipment.

Methods of Teaching / Learning

The learning and teaching strategy is designed to: 

  • develop your knowledge and understanding of fundamental audio engineering, which you will make use of and build on in subsequent modules and throughout a professional career in audio; 
  • develop your ability to investigate signal flow in an audio installation, identify faults in equipment, and solve problems in a logical manner; and 
  • develop your skills in independent research, academic writing, and academic citation, as preparation for academic work in subsequent modules. 

The learning and teaching methods include: 

  • regular lectures which cover the theoretical background to each of the topics covered - the small cohort allows plenty of opportunity for you to ask questions to help you to develop your understanding; 
  • regular workshops that allow you to apply the theoretical understanding to professional audio practice; and
  • coursework assignments that encourage you to further investigate the theoretical topics, as well as allow you to develop: your academic research and writing skills; and your logical signal tracing and fault-finding skills.

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.

Other information

Digital capabilities: the module introduces the theoretical and practical fundamentals of digital audio, giving you an accurate understanding of what the term "digital" truly means, as well as a theoretical understanding of how audio is converted to and from the digital domain. As part of the coursework assignments, you will also develop skills in: independent research of a topic, using online resources including books and academic publications; and tools for creating reports and diagrams. All these skills will be essential to your success through the remainder of the programme.

Employability: the knowledge and skills developed within this module are the fundamentals of a successful career in the audio industry. These include the decibel (used widely for measurement in most audio disciplines); transmission of audio signals (encompassing the most common methods used in industry); the theory of converting audio between analogue and digital formats (again encompassing the most common methods used in industry); the design and operation of mixing desks (essential understanding for work in a recording or broadcast studio); and audio processing equipment such as compressors and EQs (used on a wide range of audio productions). A thorough understanding of these topics, their related limitations and problems, and methods used to ameliorate these, are central to the development of high-quality audio equipment and productions. 

Sustainability: as part of the theoretical understanding of audio, the topics will also discuss aspects of sustainability in professional audio, such as the importance of backwards compatibility (for example in broadcast and modulation systems), and power efficiency (for example in broadcast and modulation systems, and in transmission of audio signals over a cable).
