Abstract
Digital forensics is the modern approach in scientific data analysis for data acquisition, analysis of data, and preservation of data contained in digital sources, which can be used as electronic evidence in cybercrime investigations. One of the essential digital forensics tasks is audio and video data analysis, also called multimedia forensics. Audio and video are digitalized sources of evidence that can be found at a crime scene, with the victim, or with the accused in audio tape from a mobile device or any CCTV footage. In cybercrime investigations, digital evidence is critical and plays a vital role in proving the crime before a court of law. As a result, audio and video forensics is the most important discipline of forensic research in the digital age. The present paper briefly discusses the basic audio-video forensics approach using simple tools.
