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Web数据集（WebDataset）格式。Web数据集文件本质上为tar归档文件，数据集中的每一条样本均以一对文件的形式存储：一个WAV音频文件与对应的JSON元数据文件。该JSON文件包含对应音频样本的类别标签及其他相关信息。 执行命令`tar tf wds-audio-test-000000.tar | head`，其输出结果如下： 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 执行命令`cat m3109_0_laughter.json`，可查看该样本的元数据内容： {"label": "laughter"}
