What BBC Sound Effects is
The BBC Sound Effects archive publishes recordings from the BBC's libraries, including the Natural History Unit: nature, weather, transport, machines, crowds, interiors and decades of radio and television foley.
Best for
Professional nature, ambience and foley recordings for personal projects, study and research.
Licence and what it means for a release
The RemArc licence allows personal, educational and research use only. Commercial use, including music releases and monetised videos, needs a separate licence, so every BBC result carries a non-commercial verdict.
How Sound Server searches it
Through the archive's search API, with WAV and MP3 downloads.
