Abstract

Un aparato para generar una señal de ocultamiento de error, comprende: un generador de representaciones de LPC (100) para generar a representación de LPC sustituta; un sintetizador de LPC (106, 108) para filtrar una información del libro de códigos utilizando la representación de LPC sustituta; y un estimador de ruido (206) para estimar un cálculo de ruido durante la recepción de tramas de audio correctas, donde la estimación de ruido se basa en el generador de representaciones de tramas de audio correctas (100) que esta configurado para usar la estimación de ruido estimada por el estimador de ruido (206) al generar la representación de LPC sustituta.An apparatus for generating an error concealment signal comprises: a generator of LPC representations (100) for generating a substitute LPC representation; an LPC synthesizer (106, 108) to filter a codebook information using the substitute LPC representation; and a noise estimator (206) to estimate a noise calculation during the reception of correct audio frames, where the noise estimate is based on the generator of correct audio frame representations (100) that is configured to use the estimate of noise estimated by the noise estimator (206) when generating the replacement LPC representation.
