Abstract

Un metodo para determinar si una senal de audio se deriva de otra senal de audio o si dos senales de audio se derivan de la misma senal de audio, compara caracterizaciones, de informacion reducida, de esas senales de audio, en donde las caracterizaciones se basan en analisis de escenas auditivas. La comparacion elimina de las caracterizaciones, o minimiza en las caracterizaciones, el efecto del desplazamiento o retardo temporal en las senales de audio (5-1), calcula una medida de similitud (5-2), y compara la medida de similitud contra un umbral. En una alternativa, el efecto del desplazamiento o retardo temporal se elimina o minimiza mediante la correlacion cruzada de las dos caracterizaciones. En otra alternativa, el efecto del desplazamiento o retardo temporal se elimina o minimiza transformando las caracterizaciones a un dominio que sea independiente de los efectos de retardo temporal, tal como el dominio de la frecuencia. En ambos casos se calcula una medida de similitud, calculando un coeficiente de correlacion. La figura mas representativa de la invencion es la numero 5.
