Full Title:Introduction to Audio Signal Processing
Language of Instruction:English
Module Code:MUSC U7009
Credits: 5
Valid From:Semester 2 - 2013/14 ( February 2014 )
Module Delivered in 1 programme(s)
Module Description:This module aims to introduce the student to the concepts and operational characteristics of the principal audio processing tools commonly used to sculpt and manipulate sounds. The module will introduce the fundamentals of processing in the amplitude, time and frequency domains and begin the process of ear training and differential auditioning of the impact of the processing.
Learning Outcomes:
On successful completion of this module the learner should be able to
  1. Define the basic concepts and typical applications of Equalization, Compression and Reverberation.
  2. Demonstrate a working knowledge of the fundamental control parameters associated with processing an audio signal's dynamics, spectral content and spatial attributes.
  3. Effectively apply the three main categories of processing to a selection of source materials.
  4. Evaluate the impact of the three processor types on the perceived quality of an audio signal.
