Abstract
1/1 resumo ocultação de perda de quadro de áudio a presente invenção refere-se a ocultar um quadro de áudio perdido de um sinal de áudio recebido executando uma análise senoidal (81) de uma parte de um sinal de áudio recebido anteriormente ou reconstruído, onde a análise senoidal envolve identificar frequências de componentes senoidais do sinal de áudio, aplicar um modelo senoidal em um segmento do sinal de áudio recebido anteriormente ou reconstruído, onde o dito segmento é usado como um quadro protótipo, de modo a criar um quadro de substituição para um quadro de áudio perdido, e criar o quadro de substituição (83) para o quadro de áudio perdido por componentes senoidais evoluindo no tempo do quadro protótipo, até ao instante de tempo do quadro de áudio perdido, em resposta às frequências identificadas correspondentes.
