Check out our Licensing page here. All of our sound effects downloads are equipped with an Individual End User License, which allows royalty-free, synchronous, commercial usage for a single user. If you have multiple users or will be using the sounds asynchronously (eg. ringtone, mobile app, toy, etc.), please contact us for a complimentary licensing consultation. We’ll get you set up with a customized license that meets your access needs and unique usage.
