GISE-51

This is a Hugging Face mirror of the core GISE-51 isolated sound event dataset from Zenodo record 10.5281/zenodo.4593514.

GISE-51 contains 51 isolated sound event classes derived from FSD50K. The upstream release also provides synthetic GISE-51-Mixtures assets. This mirror includes the extracted isolated events, label metadata, noise files, the original JAMS annotation archive for regenerating mixtures, the dataset license file, and silence_thresholds.txt.

Included Files

• isolated_events/: 16,357 mono WAV files, organized as train, val, and eval splits by class.
• metadata.csv: root-level metadata for all isolated-event WAV files.
• isolated_events/{train,val,eval}/metadata.csv: split-local metadata used by the Hub dataset viewer.
• meta/lbl_map.json: 51-class label map from the upstream release.
• noises/: background noise files used for mixture generation.
• mixtures_jams.tar.gz: original JAMS annotation archive for the mixture subsets.
• license/LICENSE-DATASET: upstream CC-BY-4.0 license text.
• silence_thresholds.txt: upstream silence filtering thresholds.

The very large pre-rendered mixture audio tarballs and pretrained model archive from the Zenodo record are not expanded in this mirror. The uploaded mixtures_jams.tar.gz, noises/, and isolated_events/ assets are the compact, reproducible ingredients for the mixture soundscapes.
