The Sound Effect Libraries industry is a subdivision of the Services Allied to Motion Picture Production industry, which is responsible for providing sound effects to various media productions such as films, television shows, video games, and commercials. Sound effect libraries are collections of pre-recorded sound effects that are licensed to production companies for use in their projects. These libraries can range from small collections of a few hundred sounds to massive collections of tens of thousands of sounds. The process of creating a sound effect library involves recording and editing various sounds, such as animal noises, explosions, and ambient sounds, and organizing them into categories for easy access. These libraries are then marketed to production companies, who can purchase licenses to use the sounds in their projects.
