Audio Forensics: technologies for digital audio analysis and enhancement

 

Advanced course for increasing the expertise on digital audio analysis and enhancement technologies for forensic purpose

Target audience:

Forensic Experts, Law Enforcement with a basic knowledge on the main tools for listening and analysis of digital audio files.

Duration:

8 hours.

Digital audio tracks (interceptions, recordings, …) are increasingly being considered as possible evidence during investigations and in trials. However, the correct acquisition and interpretation of such data often requires specific skills. The proposed training course aims to provide the skills necessary for handling and analysing digital audio data in the forensic field. The topics covered in the course draw on different fields, such as sound theory and digital audio, methods for handling digital audio in the forensic field, technologies for the analysis and processing of the audio signal. During the course are presented the main techniques for the verification of integrity and authenticity, processing and analysis of digital audio, supported by the corresponding theoretical basis. The necessary expertize to present the results coming from the analysis phase is also illustrated. Lectures will alternate with practical sessions on simple case studies, in order to put the acquired concepts into practice.

Detailed topics:

  • Fundamentals of sound and digital audio
  • Methodologies and best practices for handling digital audio in the forensic field
  • Authentication of digital audio files
  • Processing and enhancement of digital audio data
  • Interpretation of digital audio
  • Practical session on casework
