Description of the dataset
Part of the MOEB tracker (#4842) — audio→audio retrieval open slot.
FSD50K (Fonseca et al.) is a large-scale dataset of 51,213 real audio clips (Freesound recordings) spanning 200 sound-event categories organized under the AudioSet ontology, originally built for sound event classification/tagging. CC-BY-4.0, not gated — real audio files confirmed present in the HF mirror (not just metadata).
Plan: build an audio→audio retrieval task using category co-membership as the relevance signal (query clip → other clips sharing its sound-event label), sampling a benchmark-sized subset across a good spread of categories. Note: FSD50K's audio is already used elsewhere in mteb for classification (#2056) — this reuses the same permissively-licensed source for a genuinely new task direction (audio→audio retrieval), the same pattern already established for NSynth (used for both clustering and retrieval) elsewhere in this tracker.
