Abstract

Предложен способ для декодирования кодированного звукового битового потока. Способ включает в себя прием кодированного звукового битового потока и декодирование звуковых данных для формирования декодированного звукового сигнала в полосе низких частот. Способ дополнительно включает в себя извлечение метаданных реконструкции высоких частот и фильтрацию декодированного звукового сигнала в полосе низких частот гребенкой фильтров разложения сигнала для формирования фильтрованного звукового сигнала в полосе низких частот. Способ также включает в себя извлечение флажкового указателя, указывающего, должны ли выполняться над звуковыми данными спектральное преобразование или гармоническая транспозиция, и восстановление части высоких частот звукового сигнала с использованием фильтрованного звукового сигнала в полосе низких частот и метаданных реконструкции высоких частот в соответствии с флажковым указателем.
