METHOD OF AUDIO DATA COMPRESSION |
摘要 |
FIELD: information technologies. ^ SUBSTANCE: information on masked transformation ratios is excluded from an output digital flow. ^ EFFECT: increased compression ratio with preservation of high quality of subjective sound perception due to coding of value and position on the axis of frequencies of the first of non-masked coefficients of substantial discrete orthogonal transformation and distances between adjacent non-masked ratios. ^ 6 dwg |
