Abstract

An audio generation system produces streams of audio wave data and routes the audio wave data to audio buffers via logic buses that correspond respectively to the audio buffers. A logic bus, or buses, are assigned to an audio wave data source. Additionally, a logic bus corresponds to an audio buffer. Thus, any streams of audio wave data generated by the audio wave data source are routed to the audio buffer corresponding to the logic bus. A logic bus can receive streams of audio wave data from multiple sources, and route the multiple audio wave data streams to an audio buffer. Additionally, an audio buffer can receive streams of audio wave data from multiple logic buses.
