Abstract
Muchos sistemas de codificacion de audio digital de baja velocidad de transferencia de bits generan flujos de datos en los que existen bits no usados cada vez que la funcion de distribucion de bits en el codificador no utiliza todos los bits disponibles provenientes de un grupo de bits para codificar la senal de audio. Esto ocurre si la ubicacion final de bits no llega a utilizar todos los bits disponibles o si el audio de entrada no requiere todos los bits disponibles. Tales bits no usados son bits desperdiciados que no llevan informacion util. En cambio, la totalidad o algunos de tales bits desperdiciados son usados para llevar informacion. El reemplazo de bits desperdiciados por bits que llevan informacion se puede efectuar después que un codificador convencional genera un flujo de bits estándar. Alternativamente, en lugar de reemplazar algunos o la totalidad de los bits no usados en el flujo de bits por bits que llevan informacion después de la codificacion, un codificador modificado puede insertar bits que llevan informacion en algunas o la totalidad de las posiciones de bits no usados en lugar de bits nulos durante el proceso de codificacion.
