How do sound-effect licenses work?

Every plan already includes every sound effect. Without a plan you can license effects with a one-time payment: one effect for $2, or 5 effects for $3 that you pick one at a time, whenever you like.

Each effect can be used in productions published online: your own channels, work for a client and paid online ads. An effect in a 5-effect pack is licensed when you pick it; effects you have not picked yet are not licensed, and a pick cannot be moved to another effect.

TV and broadcast, trailers and cinema, and apps and games are not covered; they are available on Enterprise.
