FSD50k in WebDataset Format

This dataset is the FSD50K 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 tvf fsdk50_eval_0000000.tar |head -r--r--r-- bigdata/bigdata 40 2025-01-12 13:02 45604.json -r--r--r-- bigdata/bigdata 43066 2025-01-12 13:02 45604.wav -r--r--r-- bigdata/bigdata 46 2025-01-12 13:02 213293.json -r--r--r-- bigdata/bigdata 1372242 2025-01-12 13:02 213293.wav -r--r--r-- bigdata/bigdata 82 2025-01-12 13:02 348174.json -r--r--r-- bigdata/bigdata 804280 2025-01-12 13:02 348174.wav -r--r--r-- bigdata/bigdata 71 2025-01-12 13:02 417736.json -r--r--r-- bigdata/bigdata 2238542 2025-01-12 13:02 417736.wav -r--r--r-- bigdata/bigdata 43 2025-01-12 13:02 235555.json -r--r--r-- bigdata/bigdata 542508 2025-01-12 13:02 235555.wav $ tar -xOf fsdk50_eval_0000000.tar 45604.json {"soundevent": "Yell;Shout;Human_voice"}
