AUDIO SIGNAL ANALYSIS - 2020/1
Module code: TON1023
In light of the Covid-19 pandemic, and in a departure from previous academic years and previously published information, the University has had to change the delivery (and in some cases the content) of its programmes, together with certain University services and facilities for the academic year 2020/21.
These changes include the implementation of a hybrid teaching approach during 2020/21. Detailed information on all changes is available at: https://www.surrey.ac.uk/coronavirus/course-changes. This webpage sets out information relating to general University changes, and will also direct you to consider additional specific information relating to your chosen programme.
Prior to registering online, you must read this general information and all relevant additional programme specific information. By completing online registration, you acknowledge that you have read such content, and accept all such changes.
Module Overview
This module will introduce you to the analysis of audio signals using a combination of theory and application, and to give you the background needed for a wide range of the technical modules in each year of the Tonmeister programme.

Assessment Strategy
The assessment strategy is designed to provide you with the opportunity to demonstrate and develop your knowledge and understanding of audio signal processing.
Thus, the summative assessment for this module consists of:
- one computer-based in-class test (addresses learning outcomes 1-2);
- one in-class test (addesses learning outcomes 1-3); and
- Coursework – consisting of mathematical problems and programming tasks (addresses learning outcomes 4-8).
Formative assessment
There are no formal formative assessment components for this module, but formative feedback will be given to you in tutorials as required, and in the form of regular revision questions in lectures.
Feedback
You will receive written feedback on your coursework. You will also receive verbal feedback in lectures via revision questions and in-class discussions.
Module aims
- To build on previous mathematical knowledge and understanding to provide the relevant mathematical and signal processing background for topics in Acoustics, Electroacoustics, Computer Systems, Audio Signal Processing & Synthesis, and Audio Engineering.

Overall student workload
Independent Study Hours: 117
Lecture Hours: 30
Laboratory Hours: 3
Methods of Teaching / Learning
The learning and teaching strategy is designed to: develop your skills and knowledge in mathematics and audio signal analysis, allowing modules in later semesters to build on this.
The learning and teaching methods include:
- One two-hour lecture per week for 12 weeks
- One three-hour laboratory session
- Guided reading
- 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.
