"Royalty-free sound effect libraries contain thousands of sound effects that can be licensed for specific uses. A customer who uses royalty-free sound effects, as opposed to hiring a sound engineer to create them from scratch, can save considerable time, effort, and money. Typically, podcasters and other content producers can obtain non-exclusive rights to a single effect, or they can purchase a subscription of sorts. The subscriptions allow publishers to download a limited number of sound effects during a specified period of time. "
