T2 - Forensic Digital Data Analysis

Douglas Lacey, DL Technology LLC - Fredericksburg, VA, USA

The analysis of digital audio is often required in forensics when the provenance of recorded material is in doubt or when carved material is recovered during investigations. Methods often involve spectral and statistical analyses to determine the nature of an audio recording but this event will explore additional analyses of the data that composes a digital audio file expanding on a recent workshop given at the 46th International Conference of the AES on Audio Forensics. Following a short introduction and demonstration of the classical “hex editor” that allows the viewing of the raw contents of a file, interpretation of a file's structure, analysis of embedded metadata that otherwise may not be apparent, and real case examples will be shared.
