SADIE II Database

HRIRs were measured for each subject for a regular latitude-longitude distribution (15° elevation and variable azimuthal resolution) and for at least 12 key Ambisonic loudspeaker configurations: Octahedron (x3 orientations), Cube, Bi-Rectangle (x3 orientations), Icosehedron, 7-Design, 26pt Lebedev Grid, Pentakis Icosedodecahedron and 50pt Lebedev Grid. They were taken using Genelec 8010s at a radius of 1.2m from the center of the subject's head. BRIRs were measured for each subject for a 50pt Lebedev Grid Configuration. They were taken using Genelec 8030/40s at a radius of 1.5m from the centre of the subject's head. Headphone Responces were measured for beyerdynamic DT990 headphones. Audio data is available in 44.1K - 16bit, 48K - 24bit and 96K - 24bit .wav and AES 69 SOFA format. Measurements are labeled by azimuth and elevation in degrees accurate to 1 decimal place. Azimuth is measured anti-clockwise (to the left) about the horizontal plane. 0° marks directly in front of the subject. Elevation is measured above (positive) and below (negative) the horizontal plane. These data sets are specifically supported the Ambix Ambisonic decoder configuration files found here. By default, the config. files were designed to load measurements at 48KHz. All data was recorded and developed at The Audio Lab, Department of Electronic Engineering, University of York, UK by Cal Armstrong, Lewis Thresh and Gavin Kearney.

本数据集针对每位受试者，采集了规则经纬网格分布（仰角间隔15°，方位角分辨率可变）下的头相关冲激响应（Head-Related Impulse Response, HRIR），以及至少12种典型安比森环绕声（Ambisonic）扬声器配置：八面体（3种朝向）、立方体、双矩形（3种朝向）、二十面体、7点设计、26点勒贝德夫网格、五饰二十面体及50点勒贝德夫网格。数据采集使用真力（Genelec）8010型号扬声器，采集时扬声器距受试者头部中心半径为1.2米。
同时，本数据集还针对每位受试者采集了50点勒贝德夫网格配置下的双耳房间冲激响应（Binaural Room Impulse Response, BRIR），采用真力8030/40型号扬声器，采集时扬声器距受试者头部中心半径为1.5米。
本数据集还包含拜亚动力（beyerdynamic）DT990耳机的频响特性测量数据。
音频数据提供44.1kHz-16bit、48kHz-24bit及96kHz-24bit的WAV格式，以及AES 69 SOFA格式。所有测量数据均以方位角和仰角标注，精度精确到小数点后1位。其中，方位角以水平面为基准，沿逆时针方向（向左）计量，0°对应受试者正前方；仰角以水平面为基准，水平面以上为正值，以下为负值。
本数据集专门适配此处提供的Ambix安比森环绕声解码器配置文件，默认情况下，该配置文件将加载48kHz的测量数据。
所有数据均由英国约克大学电子工程系音频实验室的Cal Armstrong、Lewis Thresh及Gavin Kearney录制并整理。如需进一步细节，请联系相关负责人。
