Abstract
resumo patente de invenção: "dispositivo de codificação de fala/áudio, dispositivo de decodificação de fala/áudio, método de codificação de fala/áudio e método de decodificação de fala/áudio". com a presente invenção, o número de bits de codificação alocados para a codificação de espectro de banda estendida é reduzido, enquanto que a degradação da qualidade de som na banda estendida é suprimida. uma unidade de compressão de banda (105) cria combinações de espectros de sub-banda em pares de duas amostras cada, em ordem, a partir de um lado de faixa baixa em uma sub-banda de alvo de compressão de banda, seleciona um espectro que tem uma amplitude de valor absoluto grande entre as combinações, e dispõe o espectro selecionado próximo ao lado de faixa baixa em um eixo geométrico de frequência. uma unidade de recálculo de número de unidades (106) redistribui bits salvos na sub-banda para a qual a compressão de banda foi realizada a uma faixa baixa fora da banda estendida, e redistribui o número de unidades com base nos bits redistribuídos.
