Development of signal processing algorithms for a novel 3D microphone array

体育转播通过允许流媒体观众在赛事的3D视频中选择自己的视角，实现了观众参与和互动的新水平。然而，体育赛事的声音来自3D摄像机周围一系列不同位置的多个来源。为了给观众创造逼真的身临其境的体验，音轨必须与摄像机的视角方向一致。加拿大广播服务国际公司是一家在活动制作和广播技术方面处于世界领先地位的公司，该公司拥有一个新颖的3D麦克风阵列，其中32个麦克风元件成对放置在开放球面格子上。该研究项目的目标是开发定向处理算法，使麦克风可以“指向”任何所需的方向，以匹配3D视频馈送。

Sports broadcasting is achieving new levels of audience involvement and interaction by allowing streaming viewers to choose their own angle of view in 3D video of the event. However, the sounds of the sporting event come from multiple sources at a range of different positions around the 3D camera. In order to create a realistic immersive experience for the viewer, the audio track must be consistent with the direction of view of the camera. Broadcast Services International Inc., a Canadian company that is a world-leader in event production and broadcasting technology, has a novel 3D microphone array with 32 microphone elements placed in pairs on an open-sphere lattice. The goal of this research project is to develop directional-processing algorithms that allow the microphone to be "pointed" in any desired direction to match the 3D video feed.
