With the proliferation of digital technology and its interweaving into all facets of modern life, the landscape of crime and surveillance has evolved placing new demands on the forensic analyst working with digital audio. In order to address these demands, practitioners need to embrace technology dealing with the acquisition and recovery of digital data as well as advanced file searching and information gathering. This paper presents an overview of computer forensics for the forensic audio professional in an effort to help define their role in a digital world revolving around personal computers and mobile devices. With a focus on its overlap and synergy with digital audio, computer (cyber) forensics topics covered in this paper include: history and the development of standards and best practices, core competencies, methodology with a brief hardware/software overview, a sample case study, and the limitations and challenges in Digital and Multimedia Evidence (DME).
