Abstract

resumo aparelho e método para processamento de um sinal de áudio, método para gerar um fluxo de bits, produto de programa de computador, e, fluxo de dados a presente invenção refere-se a um renderizador de áudio que compreende um receptor (801) que recebe dados de entrada compreendendo dados da parte adiantada indicativos de uma parte adiantada de uma função de transferência binaural relacionada à cabeça, dados de reverberação indicativos de uma parte de reverberação da função de transferência; e uma indicação de sincronização indicativa de uma defasagem de tempo entre a parte adiantada e a parte de reverberação. um circuito da parte adiantada (803) gera um componente de áudio pela aplicação de um processamento binaural a um sinal de áudio, sendo que o processamento depende dos dados da parte adiantada. um reverberador (807) gera um segundo componente de áudio pela aplicação de um processamento de reverberação ao sinal de áudio, sendo que o processamento de reverberação depende dos dados de reverberação. um combinador (809) gera um sinal de um sinal estéreo binaural por meio da combinação dos dois componentes de áudio. a temporização relativa dos componentes de áudio é ajustada com base na indicação de sincronização por um sincronizador (805) que pode ser, especificamente, um atraso. 1/1
