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 Content

Outline Syllabus:Advanced measurement scales tools and techniques Advanced audio visualisation tools charts and techniques Strategies and limitations of surveillance techniques Advanced spectrographic audio analysis and interpretation Forensic application of digital audio processing Advanced forensic audio tools and procedures Emerging digital audio technologies Binaural trilateration and doppler calculations Fast Fourier Transforms Recognizing audio forgery using advanced critical listening procedures Implications of frequency masking HEX and EXIF interrogation of audio Over processing implications Analogue audio systems and transfer techniques Analogue transcoding Preparation of documentation for such cases Forensic audio reporting and evidence for cross examination
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.
