3D Microphone Array Recording Comparison (3D-MARCo)
收藏资源简介：
3D-MARCo is an open-access database of 3D sound recordings of musical performances and room impulse responses. The recordings were made in the St. Paul’s concert hall in Huddersfield, UK using a total of 71 microphones simultaneously. The main microphone arrays included in the database comprise PCMA-3D, OCT-3D, 2L-Cube, Decca Cubioid, First-order Ambisonics (FOA), Higher-order Ambisonics (HOA) and Hamasaki Square with height. In addition, ORTF, side/height, Voice of God and floor channels as well as a dummy head and spot microphones are included. The sound sources recorded are string quartet, piano trio, piano solo, organ, a cappella group, various single sources and room impulse responses of a virtual ensemble with 13 source positions captured by all of the microphones. 3D-MARCo would be useful for spatial audio research, recording education, critical ear training, etc.
3D-MARCo是一个开放获取的数据库，收录音乐演奏三维录音与房间脉冲响应（room impulse responses）。本次录制工作于英国哈德斯菲尔德的圣保罗音乐厅完成，通过总计71台麦克风同步完成采集。本数据库包含的主流麦克风阵列包括PCMA-3D、OCT-3D、2L-Cube、Decca Cubioid、一阶 Ambisonics（FOA）、高阶 Ambisonics（HOA）以及带高度声道的滨崎方形麦克风阵列（Hamasaki Square with height）。此外，数据库还收录了ORTF阵列、侧/高声道、上帝之声阵列麦克风（Voice of God）、地面声道，以及仿真人头麦克风阵列（dummy head）与定点麦克风（spot microphones）。本次录制的声源涵盖弦乐四重奏、钢琴三重奏、钢琴独奏、管风琴、无伴奏合唱团体、各类单一声源，以及由全部麦克风采集、具备13个声源位置的虚拟合奏房间脉冲响应。3D-MARCo可应用于空间音频研究、录音教学、关键听音训练（critical ear training）等场景。
