Es un sistema de entretención, que toma una señal de audio, la descompone y procesa mediante una serie de filtros, para luego mezclarla con otra señal de audio que proviene de un micrófono. Dichas señales, finalmente pasan por un sistema amplificador de audio, que activará unos parlantes y asi poder escuchar las señales procesadas.
Un sistema de karaoke, está limitado en cuanto a la cantidad de señales que puede procesar al mismo tiempo (una estéreo de entrada y una de micrófono), es decir, no es un “mezclador de audio”.
Para lograr la implementación del sistema, se utilizarán filtros pasa bajos y pasa altos, amplificadores operacionales, conocimientos sobre audio estéreo.
La documentación del sistema incluye documentación existente, documentación a desarrollar, y documentación a modificar.
