A Partial Retrieval of Music Data with Different Bit Rate using MPEG-4 TwinVQ Audio Compression

By Michihiro Kobayakawa and Mamoru Hoshi

Abstract

The present paper describes a method for partial retrieval of a piece of music using the autocorrelation coefficients computed in the encoding step of TwinVQ (Transform-domain Weighted Interleave Vector Quantization) audio compression (MPEG-4 audio standard). Our key contribution is to realize partial retrieval of a piece of music that is robust with respect to bit rate using an approximation relation. The approximation relation is based on the fact that the i-th autocorrelation coefficient with bit rate B1 of a piece of music computed in the encoding step of TwinVQ audio compression can approximate the j-th autocorrelation ⌊coefficient with bit rate B2 of the piec
