On "I discovered a sound that leaks your exact location (and it's everywhere) - YouTube"

This is clever OSINT work but solves a problem that doesn't actually exist for SEO practitioners — acoustic fingerprinting from plane noise is a forensic technique, not something that affects how search engines or users find you. If you're worried about location leakage through audio metadata in your content, strip the audio before uploading, use stock tracks, or employ any of the dozen existing anonymization tools that work fine. The real takeaway is that background noise in video carries more information than most creators realize, so treat it like any other metadata surface and clean it if privacy matters to you.
