DBR dataset

<strong>DESCRIPTION</strong> DBR dataset is an environmental audio dataset created for the Bachelor's Seminar in Signal Processing in Tampere University of Technology. The samples in the dataset were collected from the online audio database Freesound. The dataset consists of three classes, each containing 50 samples, and the classes are 'dog', 'bird', and 'rain' (hence the name DBR). The samples are original wav files divided into three folders, one for each class, and for each sample a metadata yaml file and an annotation text file is provided. Samples and their matching metadata and annotation files are named by the samples' Freesound ids. The metadata collected from Freesound includes the following fields: 'description', 'duration', 'id', 'license', 'name', 'samplerate', and 'username'. Annotation files contain the starting and ending timepoints for 5-second target sound segments, and the corresponding class labels.<strong>数据集说明</strong> DBR数据集是坦佩雷理工大学（Tampere University of Technology）信号处理本科研讨班构建的环境音频数据集。该数据集的样本均采集自在线音频数据库Freesound（Freesound）。数据集共包含三个类别，每个类别含50条样本，类别分别为“狗叫”、“鸟鸣”与“雨声”，其命名即取自三类目标声音的英文名称首字母。所有样本均为原始WAV（WAV）格式文件，按类别划分为三个独立文件夹存储；同时为每条样本配套提供元数据YAML（YAML）文件与标注文本文件。样本及其匹配的元数据、标注文件均以样本在Freesound的ID命名。从Freesound采集的元数据包含以下字段：“描述”、“时长”、“ID”、“许可协议”、“名称”、“采样率”以及“用户名”。标注文件包含5秒目标声音片段的起止时间点与对应类别标签。
