Authentication of Tape Recordings

  • Harry Hollien
Part of the Applied Psycholinguistics and Communication Disorders book series (APCD)


As you are aware, tape recordings are now part of almost everyone’s life, especially here in these United States. They are so common that the magnitude of their use actually is difficult to comprehend. Indeed, this already extensive utilization of both audio and videotape recordings is spreading at an accelerating rate. Witness the recent DeLorean case where federal agents attempted to demonstrate that the defendant had violated the laws involving controlled substances by the use of surreptitious video recordings. That DeLorean was not convicted is beside the point; what is relevant is that this technique is becoming an important one for gathering evidence. It is also useful in crime counter-measures, intelligence work and the courts.
