Description
US 2014/O188487 A1 Jul. 3, 2014 ficients to obtain normalized coefficients, where the normal (51) Int. Cl ization procedure computes the product of the sign of each Gioi i9MO(2013.01) coefficient of the transformed coefficients by an amplitude GIOL 25/8(2013, 015 Scaling-invariant function of any combination of the trans (52) US Cl formed coefficients; applying a quantization procedure on the
CPC................. G10L 25/18 (2013.01); G 10L 19/00 normalized coefficients to obtain the robust hash of the audio s (2013.01) content; and a comparison step where the robust hash is (58) Field of Classification Search compared with reference hashes to find a match.
