Abstract

CODIFICADOR, DECODIFICADOR E MÉTODOS PARA ADAPTAÇÃO DINÂMICA COMPATÍVEL REGRESSIVA DE RESOLUÇÃO DE TEMPO/FREQUÊNCIA NA CODIFICAÇÃO DO OBJETO DE ÁUDIO ESPACIAL. Um decodificador para gerar um sinal de saída de áudio, compreendendo um ou mais canal(is) de saída de áudio a partir de um sinal de downmix, compreendendo uma pluralidade de amostras de downmix de domínio de tempo é fornecido. O sinal de downmix codifica dois ou mais sinais do objeto de áudio. O decodificador compreende um gerador de sequência de janela (134) para determinar uma pluralidade de janelas de análise, caracterizado por cada uma das janelas de análise compreender uma pluralidade de amostras de downmix de domínio de tempo do sinal de downmix. Cada janela de análise da pluralidade de janelas de análise tem um comprimento da janela indicando o número de amostras de downmix de domínio de tempo da referida janela de análise.
