TAU Spatial Sound Events 2019 - Ambisonic and Microphone Array, Evaluation Datasets

This package consists of two evaluation datasets, TAU Spatial Sound Events 2019 - Ambisonic and TAU Spatial Sound Events 2019 - Microphone Array. These datasets contain recordings from an identical scene, with TAU Spatial Sound Events 2019 - Ambisonic providing four-channel First-Order Ambisonic (FOA) recordings while TAU Spatial Sound Events 2019 - Microphone Array provides four-channel directional microphone recordings from a tetrahedral array configuration. Both formats are extracted from the same microphone array. The recordings in the two datasets consist of stationary point sources from multiple sound classes each associated with a temporal onset and offset time, and DOA coordinate represented using azimuth and elevation angle. These evaluation datasets are part of the DCASE 2019 Sound Event Localization and Detection Task. The corresponding development datasets can be downloaded here. The IRs were collected in Finland by Tampere University between 12/2017 - 06/2018. The data collection received funding from the European Research Council, grant agreement 637422 EVERYSOUND. The foa_eval.zip, correspond to audio data of TAU Spatial Sound Events 2019 - Ambisonic evaluation dataset. The mic_eval.zip, correspond to audio data of TAU Spatial Sound Events 2019 - Microphone Array evaluation dataset. -- Version 2 updates -- The DCASE 2019 sound event localization and detection task has now ended. Hence we are releasing the reference labels for the evaluation dataset in this version. The metadata_eval.zip is the common metadata for both TAU Spatial Sound Events 2019 - Ambisonic and TAU Spatial Sound Events 2019 - Microphone Array evaluation datasets. The short2longnames.txt file consists of the corresponding names for each recording in the dataset in the development-set format, i.e., including the information of the impulse response location and the maximum number of overlapping sound events in the recording.

本数据包包含两个评测数据集，分别为TAU Spatial Sound Events 2019 - Ambisonic与TAU Spatial Sound Events 2019 - Microphone Array。这两个数据集均源自同一场景的录音，其中TAU Spatial Sound Events 2019 - Ambisonic提供四声道一阶Ambisonic（First-Order Ambisonic, FOA）录音，而TAU Spatial Sound Events 2019 - Microphone Array则提供基于四面体阵列构型的四声道指向性麦克风录音。两种格式均从同一麦克风阵列中提取得到。两个数据集的录音均包含来自多个声音类别的静止点声源，每个声源均配有对应的时域起始、结束时间，以及以方位角和仰角表示的波达方向（Direction of Arrival, DOA）坐标。这两个评测数据集均为DCASE 2019声事件定位与检测任务的组成部分。相关开发数据集可在此处下载。本次采集的脉冲响应（Impulse Response, IR）于2017年12月至2018年6月间，由芬兰坦佩雷大学完成采集。本次数据采集工作获得了欧洲研究理事会编号为637422的EVERYSOUND项目资助协议支持。foa_eval.zip 对应TAU Spatial Sound Events 2019 - Ambisonic评测数据集的音频数据。mic_eval.zip 对应TAU Spatial Sound Events 2019 - Microphone Array评测数据集的音频数据。—— 版本2更新 ——DCASE 2019声事件定位与检测任务现已结束，因此本版本同步发布评测数据集的参考标注结果。metadata_eval.zip 为上述两个TAU Spatial Sound Events 2019 - Ambisonic与TAU Spatial Sound Events 2019 - Microphone Array评测数据集的通用元数据文件。short2longnames.txt 文件包含开发集格式下数据集中每条录音对应的完整名称，其中涵盖脉冲响应位置以及录音中最大重叠声事件数量等信息。请下载与所需数据集对应的压缩包，并使用您偏好的解压工具对这些分卷压缩包进行解压。
