MSU Wonderlust to host a free online presentation about audio forensic analysis on June 25
- Thursday, June 25, 2020 from 10:00am to 11:30am
- Online via Webex
MSU Wonderlust, a lifelong learning organization, will host an online presentation about audio forensic analysis which is the scientific acquisition, evaluation and interpretation of audio evidence that is likely to end up in a court of law or some other official venue.
Rob Maher, professor of electrical and computer engineering in the Norm Asbjornson College of Engineering at Montana State University, will present "Stop! What’s that sound? Audio Forensics in 2020" via Webex.
Many law enforcement officers routinely carry recording equipment while working, including body cameras, memo recorders and dashboard systems in police cruisers. Emergency 9-1-1 call centers have audio recording systems, as do many police dispatching radio systems. Increasingly, audio evidence may include mobile phone recordings made by civilian bystanders or recordings from security surveillance systems in private homes and businesses.
Maher will describe the methods used to assess the authenticity of forensic audio recordings and the techniques applied in several case studies involving audio forensic interpretation and research. For example, can we use audio from a mobile phone video to identify someone making threats of violence? Is the subtle creak heard on an airplane’s cockpit voice recorder a telltale sign of a malfunction in the plane’s airframe resulting in a commercial airline accident? Was a gunshot heard near the boundary of Yellowstone National Park made by a poacher who encroached in the park or by a legal hunter in the forest outside the park?
Rob Maher’s research and teaching interests are in the area of digital audio signal processing, audio forensic analysis, digital music synthesis and acoustics. He occasionally serves as an expert witness in criminal and civil court cases, and he is the author of the book “Principles of Forensic Audio Analysis” (Springer, 2018). In his spare time, he enjoys music, hiking, and both road and trail running. He is a board member for Baroque Music Montana, past president of the local Big Sky Wind Drinkers running club, and a member of several amateur music groups including the Second String Orchestra (cellist).
