Assessment Strategy
The assessment strategy is designed to provide you with the opportunity to demonstrate and develop subject knowledge (theory-based coursework and exam) and digital capabilities (programming-based coursework) in audio signal processing and sound synthesis.
Thus, the summative assessment for this module consists of:
- Signal Processing Coursework – one theory and computer-based assignment (addresses learning outcomes 1-2, 5, and 7-8);
- Sound Synthesis Coursework – one computer-based practical assignment (addresses learning outcomes 6-8); and
- 2hr examination – written paper under exam conditions (addresses learning outcomes 1-4).
Formative assessment
Formative assessment and feedback will be provided in tutorials as required, during in-class exercises, and in the form of regular revision questions in lectures.
Feedback
You will receive written feedback on your coursework.
Module aims
- Give you the necessary signal processing background for a career in the audio industry
- Provide you with the necessary theoretical understanding and practical working knowledge of sound synthesis for a career in the audio industry

Methods of Teaching / Learning
The learning and teaching strategy is designed to develop your knowledge and understanding of aspects of audio signal processing and synthesis, using a combination of theory and practice. This is achieved via lectures and workshops, as well as by completion of practical programming coursework.
The learning and teaching methods include:
- Lectures that will introduce you to the fundamentals of audio signal processing
- Captured content and guided reading that will introduce you to the theory behind sound synthesis techniques
- Workshops / seminars that will allow you to gain practical experience with audio signal processing and sound synthesis techniques
- Coursework assignments and feedback
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.
