Abstract: Systems and methods for providing multi-channel audio using a reduced amount of resources for the decoding process. A 5.1 channel audio stream is divided into three stereo streams. The packets from each of three stereo streams are multiplexed to create a pseudo-5.1 channel audio stream. The pseudo 5.1 channel audio stream is then decoded and demultiplexed at the output to create the output 5.1 channel audio sound. As such, the decoder resources only have decode a single pseudo 5.1 stream. This technique is equally applicable to 7.1 or other multi-channel formats.

Abstract: An application program provides a performance manager and an audio rendition manager to produce a rendition corresponding to an audio source. The performance manager receives audio data from the audio source and instantiates audio data processing components to process the audio data. The audio rendition manager receives the audio data from the performance manager and instantiates audio data processing components to further process the audio data, including a synthesizer component that generates audio sound wave data, and audio buffers that process the audio sound wave data. The audio data processing components are instantiated as objects having an interface that can be called by the application program. The application program requests a programming reference to an interface of an audio data processing component in the performance manager, or in the audio rendition manager, by calling an interface method of the performance manager or the audio rendition manager, respectively.
