Full Title:Audio Signal Processing
Module Code:MUSC U7025
Credits: 5
Valid From:Semester 1 - 2009/10 ( September 2009 )
Module Delivered in 1 programme(s)
Module Description:This module aims to develop the student’s knowledge and skills in the application of audio signal processing tools and associated techniques. It considers the requirement for processing, it’s effective application, the difference between ‘improvement’ and ‘change’ and how corrective/enhancement tools can be successfully used in a creative manner.
Learning Outcomes:
On successful completion of this module the learner should be able to
  1. Summarise the principle concepts and operational parameters associated with audio processing in the spectral, amplitude and time domains.
  2. Apply equalisation, compression and reverberation processing tools, correctively and creatively, to enhance both singular sound source and multiple sound source events.
  3. Apply pitch correction processing to identify and correct tuning issues in previously recorded vocals and instruments.
  4. Use A/B listening techniques to identify and qualify perceived differences between processed and unprocessed sounds and also between sounds that have received different levels of processing.

Module Content & Assessment

Indicative Content
Spatial effects
Reverberation, rhythmic based delays, Haas effect, blending multiple delays, nature of tape based delays.
Application of Processing Tools for sound enhancement
Processing techniques suitable for specific genres of instrument/sound. Application intention, perceived transparency, artistic expression and surgical correction.
Processing multi-channel audio
Mix bus compression and equalisation, surround sound processing and panning.
Processing with in the context of the mix
Tailoring sounds for a specific textural, dynamic and spatial blend, identifying spectral conflicts and applying complimentary equalisation.
Processing to address specific problems
De-essing, plosive removal, dynamic equalisation, compressor side chain applications, parallel and series compression, application of Pitch Correction software.
Subjective and Objective evaluation of processing
Comparative analysis between direct and processed sounds.
Audible Adverse Artefacts of processing
Audible artifacts of processing, acceptable levels of colouration.
