All of our products are sold as royalty-free (or buyout) products and our License Agreement and the license agreements of the respective manufacturers govern their use. Royalty Free means that there are no additional fees owed for commercial use of a sound file as it is incorporated into any audio or multimedia production. Once you have purchased a sound, you have the license to use that sound as often as you like, in as many projects as you like and you will never be required to pay another fee of any kind. Sounds cannot be copied, resold or distributed as individual files. They can only be resold and distributed as incorporated into a complete production.
