Abstract

Un dispositivo de codificación mixta de dominio del tiempo / dominio de la frecuencia y método de codificación una señal de sonido de entrada, donde una contribución de excitación del dominio de tiempo se calcula en respuesta a la señal de sonido de entrada. Una frecuencia de corte para la contribución de excitación del dominio de tiempo también se calcula en respuesta a la señal de sonido de entrada, y un rango de frecuencia de la contribución de excitación del dominio de tiempo se ajusta en relación a esta frecuencia de corte. Después de calcular una contribución de excitación del dominio de frecuencia en respuesta a la señal de sonido de entrada, se suman la contribución de excitación del dominio de tiempo y la contribución de excitación del dominio de frecuencia para formar una excitación mixta del dominio de tiempo / dominio de frecuencia que constituye una versión codificada de la señal de sonido de entrada. En el cálculo de la contribución de excitación del dominio de tiempo, la señal de sonido de entrada se puede procesar en cuadros sucesivos de la señal de sonido de entrada y se puede calcular un número de subcuadros para ser utilizado en un cuadro actual. También se describen el codificador y decodificador correspondiente utilizando el dispositivo de codificación mixta del dominio del tiempo / dominio de la frecuencia.
