Forensic Sound Analyses of Cellular Telephone Recordings

By: Dr. Durand R. Begault

Recordings involving cellular telephones or personal digital assistants (“PDAs”) are increasingly the source evidence in audio forensic examinations, compared to recordings originating with other devices such as hand-held digital recorders. On modern PDA cellular telephones recordings can be made either directly to the telephone or transmitted as voice mail messages. The current investigation focuses on differences in the two types of recordings in terms of dynamic range and linearity of levels. Such information can be important for characterizing the distance of sound sources relative to the microphone and are important for understanding transformation of recorded speech and non-speech sounds.

Documents are fragile and require special handling. Not only must documents be kept in their original condition, but a chain of custody must be maintained to ensure the integrity of the documents. If everyone takes the necessary precautions to ensure the integrity of the documents, evidence will be properly preserved for court proceedings.

Imaging Forensics: Countering Bad Science

By: George Reis

When attorneys get a copy of opposing counsel's expert reports, sometimes they are quite surprised by what they read - it's just bad science. And, in these cases they will then retain their own expert to counter, and possibly quash, the other experts opinion. I've been retained in numerous cases to do this, and I'll discuss four to illustrate the benefit this has, and to help illustrate the kind of work that I do.

Imaging Forensics: When to hire an expert

By: George Reis

I was recently retained on a civil case just a month before the trial date. When called about the case, I was told that the firm never thought of hiring a forensic photographer until one showed up in opposing counsel’s expert list. In this case, I needed to photograph the scene of an accident to depict what could be seen from a specific perspective, at a specific time of day, under specific lighting conditions.

Imaging Forensics: So, What's the Story on Resolution?

Three people, all of whom have a significant background in forensic imaging, have made rather divergent comments. Multiple topics are being addressed, from crime scene, accident and evidence photography to latent print photography to SWGFAST guidelines/requirements to the resolution of video security camera systems.
