PERFORMANCE OF PHILIPS AUDIO FINGERPRINTING UNDER DESYNCHRONISATION
An audio fingerprint is a compact representation (robust hash) of an audio signal which is linked to its perceptual content. Perceptually equivalent instances of the signal must lead to the same hash value. Fingerprinting finds application in efficient indexing of music databases. We present a theoretical analysis of the Philips audio fingerprinting method under desynchronisation for correlated stationary Gaussian sources.
