Abstract
Cuando una señal de canal, tal como una señal de canal 22.2, es representada a una señal de canal 5.1, una señal acústica tridimensional puede ser reproducida. Utilizando un canal de salida bidimensional (2D). Sin embargo, cuando la elevación de un canal de entrada difiere de la evaluación estándar, el uso de un parámetro de representación de elevación, de acuerdo con la elevación estándar, puede provocar la distorsión de una imagen acústica. La presente invención resuelve el problema mencionado anteriormente de la técnica previa. Un método para representar una señal acústica, de acuerdo con una modalidad de la presente invención, para impedir el fenómeno de confusión frontal-posterior provocado por un canal de salida de sonido envolvente, comprende las etapas de: recibir una señal de multicanal que incluye múltiples canales de entrada a ser convertidos a múltiples canales de salida; añadir un retardo predeterminado a un canal de entrada de altura frontal, de tal manera que los canales de salida proveen una imagen acústica que tiene un sentido de elevación a un ángulo de elevación estándar, modificar el parámetro de representación de elevación para el canal de entrada de altura frontal en base al retardo añadido y en base al parámetro de representación de elevación modificado, generar un canal de salida de sonido envolvente elevación-representado retardado con respecto al canal de entrada de altura frontal, impidiendo mediante esto la confusión frontal-posterior.
