Abstract

Cuando una señal de múltiples canales, tal como una señal de 22.2 canales, es reproducida en una señal de 5.1 canales, las señales acústicas de tres dimensiones pueden ser reproducidas por medio de un canal de salida de dos dimensiones, aunque las señales acústicas reproducidas sean aplicadas, en forma sensible, a la disposición del altavoz, y si la disposición configurada del altavoz es diferente de la disposición estándar, ocurre la distorsión de la imagen de audio. La presente invención resuelve el problema descrito en la tecnología existente, el método para la reproducción de señales acústicas de acuerdo con una modalidad de la presente invención, que reduce la distorsión de la imagen de audio incluso cuando la disposición configurada del altavoz difiere de la disposición estándar, comprende las etapas de: recibir una señal de múltiples canales que comprende una pluralidad de canales de entrada que será convertida en una pluralidad de canales de salida; adquirir la información de desalineación para uno o más canales de salida de la ubicación del altavoz y la ubicación estándar que corresponde con cada canal de salida; y corregir, en función de la información adquirida de desalineación, la señal de localización o paneo de un canal de altura incluido en la. pluralidad de canales de entrada a un canal de salida que tiene la información de desalineación.
