Abstract

método e aparelho de codificação de sinal de áudio tridimensional e codificador. um método e aparelho de codificação de sinal de áudio tridimensional e um codificador (113) são fornecidos e estão relacionados ao campo de multimídia. o método inclui: o codificador (113) obtém uma primeira quantidade de valores de voto iniciais de quadro atual para um quadro atual de um sinal de áudio tridimensional (s610). então, o codificador (113) obtém, com base na primeira quantidade de valores de voto iniciais de quadro atual e uma sexta quantidade de valores de voto finais de quadro anterior, uma sétima quantidade de valores de voto finais de quadro atual que são de uma sétima quantidade de alto-falantes virtuais e que correspondem ao quadro atual (s620). além disso, o codificador (113) seleciona uma segunda quantidade de alto-falantes virtuais representativos de quadro atual da sétima quantidade de alto-falantes virtuais com base na sétima quantidade de valores de voto finais de quadro atual (s630). o codificador (113) codifica o quadro atual com base na segunda quantidade de alto-falantes virtuais representativos de quadro atual, para obter um fluxo de bits (s640). desta forma, a continuidade direcional de sinal entre quadros é melhorada, estabilidade de uma imagem espacial do sinal de áudio tridimensional reconstruído é melhorada, e qualidade de som do sinal de áudio tridimensional reconstruído é assegurada.
