}Evidence claims
- [upstream_claim] README: official implementation of AudioSeal, a generator that embeds an imperceptible watermark and a detector that finds it per sample (1/16000 s); works at 16k and also at 24, 44.1, 48 kHz; optional secret 16-bit message. · locator: README, intro and API description source
- [sourced_fact] README news 2024-04-02: license updated to full MIT including the model weights, so commercial use is allowed; checkpoints on Hugging Face facebook/audioseal. · locator: README, news source
- [sourced_fact] GitHub metadata: MIT, not archived, last push 2026-05-19. · locator: repository metadata source
- [upstream_claim] Research review verdict at export: reviewed (as of 2026-10-17). Recorded by the research pipeline, not a hub review outcome; evidence.review stays unreviewed until an independent reviewer records one.
