An audio library is a collection of sound recordings that can be used for various purposes, such as music production, film scoring, or video editing. These libraries often include a wide range of audio files, including music tracks, sound effects, and voiceovers, which can be licensed for personal or commercial use. Many audio libraries are available online, allowing users to search and download sounds easily. Some popular examples include Epidemic Sound, AudioJungle, and Freesound. These platforms cater to different needs, from royalty-free music to unique sound effects, making it easier for creators to enhance their projects.
