Abstract
Пропонуються способи, пристрої й комп'ютерні програмні продукти для кодування й декодування багатоканального звукового сигналу на основі вхідного сигналу. Відповідно до винаходу використовується гібридний спосіб використання як параметричного стереокодування, так і дискретного представлення обробленого багатоканального звукового сигналу, що дозволяє підвищити якість кодованого й декодованого звукових сигналів для деяких бітрейтів.
