Of the free sound-effects libraries I might use (Freesound, Sonniss GDC bundle, BBC Sound Effects, Pixabay sound effects), which say anything about AI or machine-learning training, in which document, and does the short summary page say the same as the legal text?

A comparison at dated reads. Freesound: training allowed if each sound's CC licence is respected, plus uploader preferences since July 2026. Sonniss: AI training expressly prohibited in the licence and repeated on the bundle page. BBC: AI development or training needs BBC permission. Pixabay: the licence summary page says nothing about machine learning, while the Terms of Service prohibit scraping and data mining "for machine learning purposes" and describe a contributor opt-out for Pixabay's own AI training; so a reader of the summary alone would miss the ML clause. Mixkit's sound-effects licence text is script-rendered and was not obtained. Curator qualifications: 10 of 10 excerpts present. Pixabay licence summary (decoded): 0 for machine learning, AI (word), artificial, train, data mining, scrap; ToS prohibits scraping and data mining 'for all unauthorised purposes, including without limitation for machine learning purposes' and offers contributors an opt-out from Pixabay's own AI training (rights conflict confirmed). Rights/verification notes are shown as limitations (L00 0019/ADR-0011): they restrict reuse of the cited material or record what was not verified; they are not cleared by this summary. Limitations: [rights_conflict_record] Rights conflict preserved (Pixabay summary vs ToS). [component_reuse_restriction] Mixkit licence not obtained (producer). Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
