ThinkSound publishes four incompatible-looking statements: HF weights card Apache-2.0 (S15, S16), GitHub README Apache-2.0 headline but research-only/no commercial use (S17), a bundled Stability AI Community License for the fine-tuned VAE (S18; commercial use needs registration and a revenue condition), and a paper statement that the dataset is strictly academic/non-commercial (S14). Its training sources include VGGSound (page: CC BY 4.0, copyright remains with video owners), AudioSet (CC BY 4.0 annotations for YouTube-linked data), Freesound and BBC Sound Effects (site: personal/educational use or license). A permissive label on one file does not resolve the others.
