Abstract

Methods and apparatus for implementing sound events are provided. When a first sound event is triggered, a first virtual routing channel corresponding to the first sound event is determined. A link between the first virtual routing channel and a second virtual routing channel is established according to priority information of the first sound event. The second virtual routing channel is a virtual routing channel corresponding to a currently-implemented second sound event. One or more processes are performed including: using an electrical level of the first virtual routing channel to restrain an electrical level of the second virtual routing channel through the link, and using an electrical level of the second virtual routing channel to restrain an electrical level of the first virtual routing channel through the link. Accordingly, the apparatus includes a channel determining unit, a link establishing unit, and a restraining implementation unit.
