Abstract

La presente descripción provee un método de grabación de sonido y dispositivo, el cual pertenece a campo de procesamiento multimedia; el método se aplica en una terminal móvil equipada con tres micrófonos, que incluye: adquirir tres canales de señales de sonido recolectadas por los tres micrófonos; calcular una señal de canal central, una señal de canal izquierdo, una señal de canal derecho, una señal de canal izquierdo trasero y una señal de canal derecho trasero en un canal de sonido 5.1 de conformidad con los tres canales de señales de sonido; calcular una señal de canal de graves en el canal de sonido 5.1 de conformidad con los tres canales de señales de sonido; y combinar las señales de arriba para obtener una señal de sonido del canal de sonido 5.1; la presente descripción resuelve el problema en la técnica relacionada de que los datos de audio grabados por el usuario pueden ser solamente datos de canal único o datos de canal doble y así el intervalo de campo de sonido y la detección de inmediatez de los datos de audio grabados son deficientes y logra los efectos de que el usuario puede grabar datos de canal de sonido 5.1 sin cambiar la configuración de hardware de la terminal y así se mejora la calidad de tono del archivo grabado.
