"BBC literally built the greatest sound library on the internet. It is called BBC Sound Effects, and it gives you access to more than 30,000 recordings from around the world. Just search any word, and it instantly finds matching sounds. You can filter them by category, duration, and even the continent where the sound was recorded. Every sound can be previewed inside your browser, downloaded, or added to the built-in mixer so you can layer multiple recordings together."
