EigenScape

EigenScape is a database of acoustic scenes recorded spatially using the mh Acoustics EigenMike. All scenes were recorded in 4th-order Ambisonics - ACN channel ordering with SN3D normalisation at 24-bit / 48 kHz resolution. The database contains recordings of eight different location classes: Beach Busy Street Park Pedestrian Zone Quiet Street Shopping Centre Train Station Woodland The recordings were made in May 2017 at sites across the North of England. 8 different examples of each location class were recorded over a duration of 10 minutes for 64 recordings in total. The provided metadata file gives more detail on each recording, and the EigenScape recording map (see link below) shows the locations and classes of all the recordings. EigenScape Lite is a condensed version of EigenScape designed for a more lightweight download. This version of the dataset features 1st-order Ambisonic channels only, losslessly compressed to FLAC format. Data recorded by Marc C. Green in May 2017.<br> <strong>If you make use of this database in your work, please cite the accompanying paper: https://www.mdpi.com/2076-3417/7/11/1204</strong><br> <br> <strong>Baseline classifier and segmentation tools: https://github.com/marc1701/EigenScape<br> <br> Recording map: http://bit.ly/EigenSMap<br> <br> Contact: [e-mail]</strong> _{Version 2 of the dataset has different ZIP files, as there was a problem unzipping the original files in macOS. All of the audio is identical.}EigenScape是一款采用mh Acoustics公司的EigenMike麦克风进行空间录制的声学场景数据库。所有场景均以4阶环绕声编码（Ambisonics）格式录制，采用ACN通道排序与SN3D归一化规则，采样位深为24位、采样率为48kHz。该数据库包含8类不同场景的录制样本：海滩、繁忙街道、公园、步行区、安静街道、购物中心、火车站与林地。录制工作于2017年5月在英格兰北部的多个场地开展。每类场景录制8个独立样本，每个样本时长10分钟，总计64条录制数据。附带的元数据文件可提供每条录制内容的详细信息，而EigenScape录制地图（详见下文链接）展示了所有录制数据的采集位置与场景类别。EigenScape Lite是EigenScape的精简版本，专为轻量化下载设计。该版本仅包含1阶环绕声编码（Ambisonics）通道，且已无损压缩为FLAC格式。所有录制数据由Marc C. Green于2017年5月完成采集。<strong>若您在研究工作中使用该数据库，请引用以下论文：https://www.mdpi.com/2076-3417/7/11/1204</strong><br> <br> <strong>基线分类器与分割工具：https://github.com/marc1701/EigenScape<br> <br> 录制地图：http://bit.ly/EigenSMap<br> <br> 联系方式：[e-mail]</strong> _{本数据集的V2版本采用了不同的ZIP压缩包，原因是原始压缩包在macOS系统中无法正常解压，所有音频文件内容与原版完全一致。}
