How does licensing work? Can I use a sound effect from BBC Sound Effects in my YouTube video?/ University project?
You can read the terms of the licence here. However, as a general rule, as long as your usage remains non-commercial, you can use sound effects for free, crediting the BBC. If the usage becomes commercial - i.e. if you monetise it, sell it, or charge for access to it, or if it is advertising-funded or commercially sponsored, then that counts as commercial use, and you will need to license the recording from Pro Sound Effects.
