Authors: Marr, Kenneth; Pappas, David P.

AES Conference: 33rd International Conference: Audio Forensics-Theory and Practice · Paper 14 · June 2008

Abstract

Magneto-resistive imaging of cassette tapes for forensic analysis applications is presented. Sample tapes were recorded on various tape recorders with events typically encountered in investigations. A comparison of the images with those obtained using ferrofluid is presented, along with comparisons of multiple instances of the same event with the various recorders.
