    We've all seen the TV crime shows where the forensic technician opens the grainy surveillance, then zooms in on a tiny face, license plate or scrap of paper, hits the enhance button and, magically, the image becomes sharp and clear (accompanied by appropriate background music).

    In Audio Forensics, it often comes down to ears versus microphones. In one corner, we have the human ear with all its amazing capabilities. In the other corner, the fantastic piece of technology known as the microphone, with its ability to record sound to a digital file or tape for later playback.

    A confrontation between an inmate and a Corrections Officer leads to accusations of mistreatment on one side and claims of justifiable action on the other. It was one person's word against another until an unexpected recording came to light and, with the help of sophisticated audio forensic analysis and processing, the truth was revealed.

    Pocket dialing occurs when a mobile phone's touch pad is pressed by something in a person's pocket or purse, or, if the person happens to sit down a certain way, a part of their anatomy. If the pressed key or screen surface area is programmed to dial or redial a telephone number, a call occurs. This call often goes undetected by the phone's owner. Some phones are more prone to this phenomenon than others.

    A party in a divorce case hired me after his attorney told him that his wife's council was planning to introduce audio recordings during an upcoming custody hearing.

    You have an audio recording that may be used as evidence in an upcoming court case. Looking for a way to make it easier to hear, you do an on-line search and come upon a list of "Audio Restoration companies." The ads state that these sites can lower or eliminate noise and restore recordings to their original quality.

    For forty years, PAUL KAYFETZ, INC. through Mr. Kayfetz' expert testimony, has routinely admitted the following into evidence:
  • Driverseye Visibility Studies
  • Night-Time Photography
  • Computer and Video Simulations
  • Accident Reconstruction Photos
  • Photogrammetry Photo Measuring

    Our computer engineers, video engineers and engineering photography experts:
  • Apply Accepted Engineering Measurements Procedures
  • Have Published Numerous Peer-Reviewed Engineering Papers
  • Use HD Video Systems that Produce Movie Theater Quality
  • Apply Cutting Edge Computer Techniques for Lifelike Photorealistic Images (not Computer Cartoons)
  • Coordinate with the Best Accident Reconstruction and Human Factors Experts for Technical Accuracy

    We frequently help plan complete technical testing, visibility study, computer simulation and demonstrative evidence strategy - coordinating a group of technical witnesses who are independently retained by counsel. This is requested by many clients because of Mr. Kayfetz' track record, his previous career as an attorney, his extensive contact with top experts from his forty years experience as an engineering photography consultant working with the best forensic witnesses on many of the major cases during those decades, and upon his membership and participation in major engineering societies.

    Each year we help attorneys win and save hundreds of millions of dollars in verdicts and settlements.

    This results primarily from our experience and expertise. It also stems from our ability to discover measurements from existing photos. We are ahead of everyone in our field because we invest in HD cameras costing 250,000 each, six figure computer systems, custom engineering computer programs and staff engineers - not artists.

    A major part of our work is evaluating and keeping out of evidence opponents' forensic photography, computer simulations, or computer animations which do not comply with the rules of evidence. This has swung multi-million dollar results several times in recent years.

    The explanation then given is a basic, but little understood, fundamental of the presentation of a visibility study in court. A visibility study depicts what is available to be seen by a person with normal, unimpaired vision under defined conditions similar enough to those at issue to provide relevant information about levels of visibility, lines-of-sight, timing of visibility, and to demonstrate expert witness(es)' opinions.

    Jurors jumped as the wild boar in the motorcycle headlights suddenly filled the large screen in front of them.A week later they awarded the motorcyclist several million dollars against Caltrans for not mitigating a chronic wild pig problem on Highway One in Monterey County. The jury found that the motorcyclist had a 0.10 blood alcohol level and was negligent, but that our HD-video visibility study showed that even an unimpaired driver could not have seen the pig in time to avoid it.

    The objective of this article is to report on the integration of improved video and related computer technology into existing, long-accepted visibility study preparation and presentation methodologies. The result has been an incremental extension of the types of visual environments which can be reproduced with substantial similarity for admission as visibility evidentiary exhibits in court

    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.
