Abstract

Se describe un enfoque que obtiene coeficientes de espectro para un cuadro de reemplazo (m) de una señal de audio. Un componente tonal de un espectro de una señal de audio se detecta sobre la base de un pico que existe en los espectros de cuadros anteriores a un cuadro de reemplazo (m). Para el componente tonal del espectro se predicen coeficientes de espectro para el pico (502) y su entorno en el espectro del cuadro de reemplazo (m), y para el componente no tonal del espectro se utiliza un coeficiente de espectro no previsto para el cuadro de reemplazo (m) o un coeficiente de espectro correspondiente de un cuadro anterior al cuadro de reemplazo (m).
