Abstract
Se presentan un método y un aparato para insertar una senal de datos en una senal de audio, con el proposito de proveer una senal etiquetada.El método incluye: eliminar una banda de frecuencia, centrada en una frecuencia de muesca predeterminada, dela senal de audio; formarespectralmente la senal de datos para que asuma la forma precisa y la magnitud de la envolvente de la senal de audio en la banda eliminada; e insertarla senal de datos formada en la banda eliminada de la senal de audio. Elmé todo puede emplearse para identificar un segmento de audio o puede usarse paracodificar la senal de audio con otros datos deseados. El método de la invencion hace que la senal de datos sea virtualmente inaudible para el oyentedel segmento deaudio, p ero lo suficientemente robusta para subsistir al severo procesamiento de la senal de audio.
