Yes, that’s why we are here! Our sound effects are royalty free, meaning you license (purchase) them once and can use them as many times as you want without further costs. The license you get when purchasing through our site covers you for use within your app or project, as long are synchronized or used in conjunction with a moving image. It does not cover the sounds when they are used as standalone elements such as ringtones or when users are allowed to select which sound they want or redistribution. Additional licenses can be obtained for these or any non-standard use of our sounds. Contact us for more details. See our Licensing page for details.
