- Description
- 3D immersive audio rendering systems use algorithms that accurately render the perceived location of an audio source within a space using multiple sets of loudspeakers. The algorithms used by these renderers can become very processor intensive as the number of tracks and loudspeakers being used increases. The ImmerGo spatial audio system provides a solution to this by using distributed endpoint processing. ImmerGo uses a client-server architecture that controls multiple smaller endpoints distributed on an Ethernet Audio Video Bridging (AVB) network. Each endpoint contains an audio mixer which is dedicated to mixing audio to a smaller subset of speakers according to commands from ImmerGo. The ImmerGo system performs its rendering calculations within the host computer and then mixes the audio at each endpoint. The work in this thesis identified that the processing load put on the host computer due to these calculations may be mitigated by offloading the rendering algorithm calculations to the endpoints as well. In order to prove this for a number of different algorithms, the ImmerGo system was modified to include three new algorithms as well as the one it currently uses. Each algorithm then had its processing offloaded to the endpoints at three successive steps of distribution. Tests were performed to determine the limitations of each step, and how the host processor and endpoint processors were affected by distributing the calculations. Listening tests were also performed to ensure that each newly introduced algorithm was implemented correctly.
