Conference Paper

Large Scale Test of Digital Audio File Structure and Format for Forensic Analysis

Authors: Grigoras, Catalin; Smith, Jeff

AES Conference: 2017 AES International Conference on Audio Forensics · Paper 1-6 · June 2017

Abstract

This paper presents an extensive study on MP3, WAV and WMA file structure and format analysis for forensic purposes. It is common nowadays for the authenticity of digital audio recordings to be challenged before being accepted as evidence in the courtrooms. The forensic digital audio authentication framework includes the structure and format analysis that requests the investigation of the suspect recording device as well. Sometimes the suspect recorder is not available for test reference recordings and this can be a reason to reject the expertise. This paper presents the analysis of audio files collected over an 18 year span from more than 125 digital audio recorders and 40 commercially available software applications.
