Sound Processing


Content, progress and pedagogy of the module

This class introduces the fundamental sound technology of digital signal processing from the viewpoint of sound synthesis and digital audio effects. Signal processing is concerned with the theory and practice behind acquisition, analysis, modification, and reconstruction of signals. It involves such theory as sampling and quantization, linear time-invariant systems, difference equations, the Fourier transform in its various forms, and the z-transform. The proper application and development of such systems requires competences in the acquisition and manipulation of sounds.

Learning objectives


Students who complete the course module will obtain the following qualifications:

  • Understand the basic filter types, such as low-pass, high-pass, band-pass, etc., filters and  filter design methods
  • Understand delay lines and delay based effects (flangers, vibrato, chorus, echo) as well as modulators and demodulators
  • Understanding spatial effects


Students who complete the course module will obtain the following qualifications:

  • Design, implement and apply filters to sound and music signals and evaluate the results
  • Apply the z-transform to analysis and design of filters
  • Apply signal processing theory to the design of filters and digital audio effects


Students who complete the course module will obtain the following qualifications:

  • Apply appropriate methods and tools to the design of a sound processing system comprising filters and/or audio effects
  • Apply appropriate methods, tools, and programming paradigms to implement real-time sound effects
