Q. For pay-per-track mode, how much does it cost to license tracks?
A. Individual sound effects are priced from $1.00 and up, typically depending on the length and quality and uniqueness of each sound effect. Music tracks vary from a few dollars up to hundreds or even a thousand dollars or more depending on how you intend to use the music. For music pricing in general, the price for a license depends on how you intend to use the music for your project.
For most premium content tracks (labeled with ), especially for music, when you add them to your shopping cart, select the scope of the license you wish to purchase in terms of how you intend to use the content in your commercial production or product. The price is adjusted accordingly wherein broader usage of a music track (for instance, in a worldwide motion picture) is more expensive than local usage of the same track (for instance in a local theater production).
For commercial use pricing, most music tracks have a (plus/minus) symbol listed after the displayed "base price". This symbol indicates that the price of a commercial use license for the track is variant, and goes up or down from the base price depending on the scope of the license you wish to purchase. Licenses with a longer term or larger territory are more expensive than licenses with limited term and territory.
