  • Publication number: 20180365031
    Abstract: A method and device for sound effect processing, and a non-transitory storage medium. The method includes the following actions. A task manager is traversed to determine whether a sound effect service process for a sound effect service exists. Responsive to determining that the sound effect service process exists, whether the sound effect service process is a system process of a system, is determined. When the sound effect service process is not a system process of the system, the sound effect service process is set to be a system process of the system.
