Spatial Audio Multicast Server for Multiplayer Network Load Reduction

The patent introduces a server as an intermediary to receive audio data from all players and redistribute it to other players. Instead of direct peer-to-peer transmission (N(N-1) connections), the server acts as a central hub that consolidates audio streams and delivers them efficiently to multiple clients, reducing network load while maintaining spatial audio quality through proper mixing and distribution.

The server acts as an intermediary that performs the computationally intensive audio mixing and spatial positioning calculations. Instead of requiring each mobile device to process multiple audio channels locally, the server handles the mixing of N player audio streams into appropriate spatial configurations for each client, significantly reducing the processor load and battery consumption on client devices while maintaining accurate spatial audio positioning.

The patent divides the audio mixing computation into segments handled by different servers in a distributed architecture. Instead of requiring one server to handle all N players simultaneously, the system segments the player group and assigns different subsets of players to different servers for mixing. This distributes the computational load across multiple servers, each handling a manageable subset of audio streams, thereby scaling the system's productivity to support larger numbers of players.

The server intermediary receives and processes the full set of N audio input channels from all players, performing the mixing computations centrally. The mobile client devices then receive pre-mixed audio streams requiring minimal local processing. This arrangement allows the system to maintain high spatial audio quality by preserving all input channels during server-side mixing, while the client devices operate with reduced processor loads since they receive ready-to-play mixed audio rather than needing to process multiple raw input channels.
