Recently a client came to us asking for a tampering analysis. Without getting into the specific details of the case, we were tasked to perform an exhaustive examination of an audio file, looking for signs of tampering at the “sample” level of audio – in this case 1/48000 of a second. While we could easily have only concentrated on what the client asked for, we took the time to thoroughly listen to the file and consider the clients position. After taking everything into consideration, we did an audio enhancement on the supplied evidence and began to dig deeper into what was actually recorded. We uncovered audio that blew the case wide open. It turned out that the tamperer unknowingly used audio that exonerated our client! We discovered audio evidence that had nothing to do with the tampering! Only by seeing the whole picture and not just one viewpoint, were we able to use our experience to help our client in ways they couldn’t even imagine and do more than just “process a file”.
