This paper addresses the various aspects of audio and video authentication and signal processing as they apply to the introduction of such materials into evidence in the civil and criminal court justice system. The nature of these audio/video materials is usually that of "surveillance tapes," which are sometimes bandwidth limited, and of poor quality. Issues such as tape enhancement, signal processing voice identification, editing or tampering, or physical degradation which must be addressed by the Forensic Examiner, will be discussed.
