Abstract
Se proporciona un dispositivo de codificación de voz-sonido, un dispositivo de decodificación de voz-sonido, un método de codificación de voz-sonido y un método de decodificación de voz-sonido que realiza eficientemente la distribución de bits y mejora la calidad del sonido. La unidad de identificación de bandas de frecuencia dominantes (301) identifica una banda de frecuencia dominante que tiene un valor de factor de norma que es el valor máximo dentro del espectro de una señal de voz-sonido de entrada. Las unidades de determinación de grupos dominantes (302-1 a 302-N) y una unidad de determinación de grupos no dominantes (303) agrupan todas las sub-bandas en un grupo dominante que contiene la banda de frecuencia dominante y un grupo no dominante que no contiene una banda de frecuencia dominante. Una unidad de distribución de bits de grupos (308) distribuye bits a cada grupo en la base de la energía y la distribución de norma de cada grupo. Una unidad de distribución de bits de sub-bandas (309) redistribuye los bits que han sido distribuidos a cada grupo a cada sub-banda de acuerdo con la relación de la norma con respecto a la energía de los grupos.
