DESED in WebDataset Format

This dataset is the DESED 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 wds-audio-eval-000002.tar|head -r--r--r-- bigdata/bigdata 332 2025-01-22 20:06 Y7bebYVKl7t8_510_000_520_000.json -r--r--r-- bigdata/bigdata 320044 2025-01-22 20:06 Y7bebYVKl7t8_510_000_520_000.wav -r--r--r-- bigdata/bigdata 212 2025-01-22 20:06 Y7HSpbwWrii0_10_000_20_000.json -r--r--r-- bigdata/bigdata 320044 2025-01-22 20:06 Y7HSpbwWrii0_10_000_20_000.wav -r--r--r-- bigdata/bigdata 72 2025-01-22 20:06 Y7O_Q7A8LAhI_220_000_230_000.json -r--r--r-- bigdata/bigdata 320044 2025-01-22 20:06 Y7O_Q7A8LAhI_220_000_230_000.wav -r--r--r-- bigdata/bigdata 133 2025-01-22 20:06 Y7-Pb33nUWKI_40_000_50_000.json -r--r--r-- bigdata/bigdata 320044 2025-01-22 20:06 Y7-Pb33nUWKI_40_000_50_000.wav -r--r--r-- bigdata/bigdata 72 2025-01-22 20:06 Y7pxNDwMWoIo_20_000_30_000.json -r--r--r-- bigdata/bigdata 320044 2025-01-22 20:06 Y7pxNDwMWoIo_20_000_30_000.wav $ cat Y7bebYVKl7t8_510_000_520_000.json { "sample-00": {"onset": 0.0, "offset": 1.41, "label": "Blender"}, "sample-01": {"onset": 1.157, "offset": 3.396, "label": "Speech"}, "sample-02": {"onset": 3.649, "offset": 5.828, "label": "Speech"}, "sample-03": {"onset": 6.075, "offset": 8.878, "label": "Speech"}, "sample-04": {"onset": 9.172, "offset": 10.0, "label": "Speech"} }
