You might not realize it, but audio can be just as crucial to solving a case than video or eyewitness testimony. But understanding how to interpret audio evidence, or having the ability to enhance it to a point of intelligibility, requires highly-specialized training and expensive software. Meet Kent Gibson, one of the country's leading forensic audio experts, who's done audio analysis for the FBI, the Secret Service, and the Department of Homeland Security, among many others, and get his take on audio evidence from the missing Malaysian Airlines flight, the Trayvon Martin case, and Mel Gibson's infamous domestic dispute.
