Aims
To provide students with the theory, processes and techniques in the emerging field of Audio Forensics
To equip the student with knowledge and understanding to critically analyse, select and apply appropriate techniques to transcode, authenticate, enhance, interpret and report on forensic media investigations
To foster an environment that encourages self-reliance, professionalism and promotes continuous learning self-development and a culture that addresses the potential impact of various forms of bias can have on the interpretation of results within the evidence chain

Module Overview:
This module builds on the Basic introductory knowledge accumulated in previous modules and will provide students with a thorough understanding of the advanced practical theory, skills, processes and procedures pertinent to their current /potential role as Audio Forensic Specialist. The focus will be on many common real-life situations although there may be scope to further specialise in specific areas of the field. The Syllabus involves applying the Audio Forensic process chain appropriately with a keen awareness of the risks and implications associated with the standards and processes required for each procedure. The training is completed to a level of competence where the student is able to defend materials in court.
