Abstract
LA EFICIENCIA DE PROCESAMIENTO DE UN PROCESO UTILIZADO PARA DECODIFICAR CUADROS DE UN FLUJO DE BITS AC-3 MEJORADO SE MEJORA PROCESANDO CADA BLOQUE DE AUDIO EN UN CUADRO SOLO UNA VEZ. LOS BLOQUES DE AUDIO DE DATOS CODIFICADOS SE DECODIFICAN POR ORDEN DE BLOQUE EN LUGAR DE POR ORDEN DE CANAL. SE REVELAN LOS PROCESAO DE DECODIFICACION EJEM'PLARES PARA LA CARACTERISTICAS DE CODIFICACION DE FLUJO DE BITS MEJORADO COMO EL PROCESAMIENTO DE TRANSFORMADA HIBRIDA ADAPTATIVA Y LA EXTENSION ESPECTRAL
