Abstract
Se proporciona un método para realizar el control de la ganancia en señales de audio. En algunas implementaciones, el método involucra determinar las señales mezcladas de manera descendente, asociadas con uno o más canales de mezclado descendente, asociados con un cuadro actual de una señal de audio a ser codificada. En algunas implementaciones, el método involucra determinar si existe una condición de sobrecarga para un codificador. En alguna implementación, el método involucra determinar un parámetro de la ganancia. En algunas implementaciones, el método involucra determinar al menos una función de transición de la ganancia, basándose en el parámetro de la ganancia y un parámetro de la ganancia asociado con un cuadro anterior de la señal de audio. En algunas implementaciones, el método involucra aplicar la al menos una función de transición de la ganancia a una o más de las señales mezcladas de manera descendente. En algunas implementaciones, el método involucra codificar las señales mezcladas de manera descendente en conexión con la información indicativa del control de la ganancia aplicado al cuadro actual.
