Non-invasive Identification of Audio Content for High-resolution Applications

A non-invasive method of audio file identification is described to ascertain the proximity of processed audio, of possibly dubious origin, to a reference file. A differential correlation function forms the basis of a comparative metric. Testing embraces linear and non-linear processes including perceptual based codecs. Applications include DVD_A and SACD when used as the only legitimate non-watermarked release formats.
