Abstract
Cuando una señal de canales múltiples, tal como uno de 22.2 canales, es emitida a una de 5.1 canales, las señales acústicas tridimensionales pueden ser reproducidas por medio de un canal de salida bidimensional, pero cuando la elevación del canal de entrada difiere de la elevación estándar y un parámetro de emisión de elevación que corresponde a la elevación estándar es utilizado, ocurre una distorsión de la imagen de audio. La presente invención resuelve el problema descrito en la tecnología existente, y un método para emitir señales acústicas de acuerdo a una modalidad de la presente invención, que es para reducir la distorsión de la imagen de audio incluso cuando la elevación del canal de entrada difiere de la elevación estándar, comprende los pasos de: recibir una señal de canales múltiples que comprende una pluralidad de canales de entrada para ser convertidos a una pluralidad de canales de salida; adquirir un parámetro de emisión de elevación para un canal de entrada de altura que tiene un ángulo de elevación estándar, de modo que cada canal de salida proporciona una imagen de audio que tiene una sensación de elevación; y renovando el parámetro de emisión de elevación para un canal de entrada de altura que tiene un ángulo de elevación establecido diferente del ángulo de elevación estándar.
