VocalSound 16k in WebDataset Format

This dataset is the VocalSound dataset, formatted in the WebDataset format. WebDataset files are essentially tar archives, where each example in the dataset is represented by a pair of files: a WAV audio file and a corresponding JSON metadata file. The JSON file contains the class label and other relevant information for that particular audio sample. $ tar tf wds-audio-test-000000.tar | headm3109_0_laughter.jsonm3109_0_laughter.wavf0238_0_sniff.jsonf0238_0_sniff.wavm0526_0_cough.jsonm0526_0_cough.wavm0886_0_sneeze.jsonm0886_0_sneeze.wavo1897_0_laughter.jsono1897_0_laughter.wav $ cat m3109_0_laughter.json{"label": "laughter"}本数据集为VocalSound数据集，采用WebDataset(WebDataset)格式进行组织。WebDataset文件本质上为tar归档文件，数据集中的每个样本均由一对文件表示：一个WAV音频文件与对应的JSON（JavaScript对象表示法）元数据文件。JSON元数据文件包含该音频样本的类别标签及其他相关信息。 执行`tar tf wds-audio-test-000000.tar | head`命令可查看该归档文件的前若干条目，示例如下： m3109_0_laughter.json、m3109_0_laughter.wav、f0238_0_sniff.json、f0238_0_sniff.wav、m0526_0_cough.json、m0526_0_cough.wav、m0886_0_sneeze.json、m0886_0_sneeze.wav、o1897_0_laughter.json、o1897_0_laughter.wav 以`m3109_0_laughter.json`为例，执行`cat m3109_0_laughter.json`命令可查看其文件内容，输出示例如下： `{"label": "laughter"}` 该JSON字段表明对应音频样本的类别标签为“笑声”。
