Module Content

Outline Syllabus:
Introduction to Forensic Audio Sound and Acoustic Theory. Audio Signal Chain theory Modern Audio capture and storage techniques. Digital Audio Coding and common compression techniques. Benchmarking and Reference Equipment setup. Forensic Audio Handling Techniques. Forensic Audio Software. Forensic Audio Processing techniques for identifying Authenticity. Continuity. Forensic Audio Processing for Analysing file components. Critical listening evaluation. Electric Network Frequency Analysis. Forensic Audio Enhancement and Interpretation Techniques. Forensic Audio Interpretation Methodology and Calculations. Forensic Audio Reporting. Common Forensic Audio Case Files. Consideration of the impact of AI on audio forensics.

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: 1. Capture/ Duplication/Handling of files from original format in professional manner. 2. Transfer of files to digital analysis software. 3. Authentication Assessment of files. 4. Manipulation and Interpretation of Audio files in Analysis Software for forensic investigation processes. 5. Safe storage and transfer techniques. 6. Quality Assessment and Documentation for effectiveness, acceptability, impact accuracy and repeatability of the forensic audio processes completed to a level of competence where the student is able to defend their decision process under professional cross examination.
Module Overview:
This module will provide students with a thorough understanding of the relevant skills, processes and procedures pertinent to their potential role as an Audio Forensic Specialist. The focus will be on many common audio forensic real life situations, although there may be scope to specialise in specific areas of the industry.
