Abstract
Se proporcionan un método y un aparato para determinar un parámetro de diferencia de tiempo inter-canal para reducir una cantidad de cálculos en un proceso para buscar y calcular una diferencia de tiempo inter-canal en un proceso de codificación estéreo; el método incluye: determinar un parámetro de referencia de acuerdo con una señal de dominio de tiempo en un primer canal de sonido y una señal de dominio de tiempo en un segundo canal de sonido, en donde el parámetro de referencia está correspondiendo a una secuencia para obtener la señal de dominio de tiempo en el primer canal de sonido y la señal de dominio de tiempo en el segundo canal de sonido, y la señal de dominio de tiempo en el primer canal de sonido y la señal de dominio de tiempo en el segundo canal de sonido están correspondiendo a un mismo periodo de tiempo (S110); determinar un rango de búsqueda de acuerdo con el parámetro de referencia y un valor límite Tmax, donde el valor límite Tmax se determina de acuerdo con una tasa de muestreo de la señal de dominio de tiempo en el primer canal de sonido, y el rango de búsqueda cae dentro de [Tmax, 0], o el rango de búsqueda cae dentro de [0, Tmax] (S120); y ejecutar el procesamiento de búsqueda dentro del rango de búsqueda con base en una señal de dominio de frecuencia en el primer canal de sonido y una señal de dominio de frecuencia en el segundo canal de sonido para determinar un primer parámetro de diferencia de tiempo inter-canal lTD correspondiente al primer canal de sonido y el segundo canal de sonido (S130).
