At the Audio Engineering Society Detroit Section Meeting January 19, 2011, I will be presenting a program on Audio/Video Forensics: In the Studio.
This meeting is open to all interested parties.

Lecture Synopsis:
Audio/video technology is advancing every day. These advancements continually change the way audio/video evidence is analyzed and interpreted. This presentation will demonstrate some of the ways audio/video forensic technology is being used to help resolve court cases.

When analyzing audio/video evidence, you have to suspend personal experience and rely solely on technical training, experience and facts. If segments of a recording are missing, then that can change the interpretation of the evidence. An experienced analyst can tell when a segment has been deleted, modified or altered. Sometimes with an original recording, the missing information can be retrieved, thus giving the opportunity for a fuller, more accurate analysis.

When analyzing motion pictures, what you see is not always what you have. Example: When Hollywood shows a building exploding in your face… do you really think they have the camera that close? In such a case, the camera is a safe distance away with a special lens to pull the building and action in close. But doing so leaves clues that the experienced analyst recognizes that tells them immediately how this shot was produced. Similar training and experience is used when analyzing audio evidence.

The presentation will show examples of how audio/video analysis completely changed the outcome of court cases and how Daubert standards apply to analysis of evidence.
