Abstract

Заявлены процессор или способ обработки динамических свойств аудио, которые используют механизм или последовательность операций перенастройки, для того чтобы быстро приспособиться к изменениям контента в звуковом сигнале. Сигнал перенастройки может формироваться с помощью анализа самого звукового сигнала, или перенастройка может запускаться от внешнего события, такой как изменение канала на телевизионном приемнике или изменение выбора входа на аудио/видеоприемнике. В случае внешнего пускового сигнала, один или больше признаков состояния процессора динамических свойств для текущего источника звука могут храниться и ассоциативно связываться с таким источником звука перед переключением на новый источник звука. Потом, если система переключается наза�
