Abstract

MéTODOS E APARELHOS PARA CODIFICAçãO E DECODIFICAçãO DE SINAIS DE áUDIO COM BASE EM OBJETO. Um método e aparelho de decodificação de áudio e um método e aparelho de codificação de áudio que podem processar de forma eficiente sinais de áudio com base em objeto são fornecidos. O método de decodificação de áudio inclui o recebimento de um sinal de mistura descendente e informação secundária com base em objeto, o sinal de mistura descendente compreendendo pelo menos dois sinais de canal de mistura descendente, a extração da informação de ganho a partir da informação secundária com base em objeto e a geração da informação de modificação para modificar os sinais de canal de mistura descendente, canal por canal, com base na informação de ganho; e a modificação dos sinais de canal de mistura descendente pela aplicação da informação de modificação aos sinais de canal de mistura descendente.METHODS AND APPARATUS FOR OBJECT BASED AUDIO SIGNALING AND DECODING. An audio decoding method and apparatus and an audio encoding method and apparatus that can efficiently process object-based audio signals are provided. The audio decoding method includes receiving a downlink signal and object-based secondary information, the downlink signal comprising at least two downlink channel signals, extracting gain information from the secondary information. object-based and modifying information generation to modify down-mix channel signals, channel by channel, based on gain information; and modifying the down mix channel signals by applying the modification information to the down mix channel signals.
