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.
Written by an author with expertise in both theory and applications, 3D Sound for Virtual Reality and Multimedia provides readers an essential technical foundation in sound and virtual reality. The book covers components of spatial auditory displays; psychoacoustics of spatial hearing; what sounds are appropriate to spatialize; applications to human-machine interfaces (including virtual reality and multimedia); computer music; and room acoustics.

The formal procedures for the scientific authentication of audio media in investigative matters and legal proceedings have been updated as a result of the widespread conversion from analog to digital technology since the 1990s.
Authenticity examinations of VHS (video home system) cassettes are commonly performed in forensic laboratories and can usually determine whether a submitted recording is original, continuous, and unaltered. One of the important determinations of this analysis is identifying any portions that have been recorded over

Introduction to Environmental Forensics, Second Edition, by Brian L. Murphy (Author, Editor), Robert D. Morrison (Author, Editor). helps readers unravel the complexities of environmental pollution cases. It outlines techniques for identifying the source of a contaminant release, when the release occurred, and the extent of human exposure. Written by leading experts in environmental investigations, the text provides detailed information on chemical "fingerprinting" techniques applicable to ground water, soils, sediments, and air, plus an in-depth look at petroleum hydrocarbons.
Archaeology is founded implicitly on the concept of the site, making a careful distinction between sealed sites—presumed to have complete temporal integrity—and the surface record, which is generally considered to be without chronological resolution. While most American archaeologists focus on reconstructing events and episodes at camps, pueblos, and villages, the authoer questions this distinction. Instead, he characterizes the archaeological record as an accumulation of many human events superimposed upon each other across time and distance.

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.
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.
My post on Synchronizing Video has generated a few comments related to image 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.
