DATA COMPRESSION ALGORITHMS FOR HIGH DEFINITION DIGITAL AUDIO USING MULTI-PULSE ADAPTIVE SUB-BAND CODING (MASC)
RKC TAN, MOJ HAWKSFORD · 2024
A system of data compression is proposedfor use with an oversampled and noise shaped High De nition Digital Audio (HDDA) format (20 bits/88.2kHz) which enables the performance parameters of a linear PCM format (16 bits/44.! kHz) to be extended.An qjicient coding algorithm based upon the psychoacaustic characteristic: of the human auditory System is incorporated Research has consideredfour fundamental coding techniques, to determine their suitability with rub-band coding, ie.APCM, ADPCM, ADM and LPG.Proposed a: the Multi-puLt-e Adaptive Sub-band Coding(MASC) technique, the HDDA system combines the application of linear predictive coding (LPC) and sub-band coding (SEC).
