Game Sound Control Merging Multiple Audio Sources

The patent combines multiple sound sources into a single sound source by selecting one sound generating object to represent multiple objects. This is achieved by comparing positional relationships between the player character and multiple sound generating objects, then designating one object (typically the closest or most relevant) to produce sounds for all selected objects. This merging approach maintains sound quality while significantly reducing processing load and device complexity.

The patent applies local quality by making the sound source selection dependent on the specific positional relationship between the player character and sound generating objects. Different objects are selected as sound sources based on their local spatial context - for example, the closest object or the object in a specific directional relationship to the player. This ensures that sound quality is maintained in each local context while still reducing the overall number of active sound sources.

The patent changes the selection parameter from simple distance-based priority to a more sophisticated criterion that considers the positional relationship between the player character and sound generating objects. Instead of always selecting the closest object, the system selects objects based on their spatial relationship to the player, such as being in front, behind, left, or right of the player. This parameter change allows ambient sounds to be preserved while still reducing the number of active sound sources to improve processing efficiency.
