Audio licensing is the process of obtaining permission to use audio content, such as music, sound effects, or spoken word recordings, in various projects. This permission is typically granted through a legal agreement that outlines how the audio can be used, the duration of use, and any associated fees. Different types of licenses exist, including sync licenses for pairing music with visual media and master licenses for using specific recordings. Proper audio licensing ensures that creators and rights holders are compensated for their work while allowing users to legally incorporate audio into their projects.
