Abstract

Цей винахід передбачає способи, пристрої та комп'ютерні програмні продукти для нерівномірного квантування параметрів, що належать до параметричного просторового кодування звукових сигналів. Винахід також стосується способу й пристрою відновлення звукового об'єкта в системі декодування звуку, що враховує нерівномірно квантовані параметри. Згідно з винаходом такий підхід уможливлює зниження бітових витрат без істотного зниження якості відновленого звукового об'єкта.
