Abstract

Загалом, описані методи стиснення розкладеного представлення звукового поля. Пристрої, що містять один або більше процесорів, можуть бути виконані з можливістю здійснення методів. Один або більше процесорів можуть бути виконані з можливістю одержання бітового потоку, що містить стиснену версію просторового компонента звукового поля, причому просторовий компонент генерується шляхом здійснення векторного синтезу відносно множини коефіцієнтів сферичних гармонік.
