Forensic Authenticity Analyses of Audio/Video Evidence

Whether you are the proponent or opponent of the audio or video evidence, expert determination of a recording’s authenticity may at least affect the weight of the evidence, if not make a difference in its admissibility. Please note that Dr. Yonovitz and Mr. Joe have been authenticating audio and video  evidence for over 52 combined-years, and their authenticity procedures have overcome the only two Daubert challenges mounted against them.

As unbiased forensic audio/video examiners, Y&J can objectively, thoroughly and properly authenticate both the content and magnetic patterns of the recording(s) at issue. The most thorough forensic analysis is of the original tape(s)/recording(s) and the putative original recorder(s). Thorough Forensic Authenticity Analysis of a recording ensures that evidence of any type of tampering will be exposed, and any signs suggestive of falsification will be appropriately analyzed and explained. (A recording may be also analyzed to determine whether or not that it is the original or if it is a copy.)

Beware of examiners who misconstrue poor recordings for tampered recordings, or examiners who cannot detect all types of signs suggestive of falsification.

Clearly, the same objectivity and competency are required to reveal and demonstrate authenticity or tampering -- regardless of “which side” retains our services.
