Compact Spherical Loudspeaker Array Instrument Directivity Database

This data set contains full three-dimensional turntable measurements of a compact spherical loudspeaker array used to reconstruct the frequency-dependent radiation patterns of musical instruments. Included in this data set are array radiation control filters, driver equalization filters, measured turntable data, and simulations of the compact spherical loudspeaker array's performance using both a spherical-cap and a point-source model. For more information on the details of this data set, please refer to the paper: M. Neal, "A compact spherical loudspeaker array for efficiently recreating instrument directivities," Journal of the Audio Engineering Society (2020).

本数据集包含用于重构乐器随频率变化的辐射方向图的紧凑型球形扬声器阵列的全三维转台测量数据。本数据集涵盖阵列辐射控制滤波器、驱动器均衡滤波器、实测转台数据，以及分别采用球冠模型与点源模型对该紧凑型球形扬声器阵列性能开展的仿真结果。如需了解本数据集的更多细节，请参阅以下论文：M. Neal，《用于高效还原乐器指向性的紧凑型球形扬声器阵列》，音频工程学会期刊（Journal of the Audio Engineering Society），2020年。
