Metadata is data that provides information about other data. In the context of audio and video files, metadata typically includes information about the content of the file, such as its title, artist, album, genre, and other relevant details. This information is typically embedded in the file itself, and can be used by media playback software and other applications to provide information about the content, and to enable users to search for and organize their media collections. Metadata can also include technical information about the file, such as its resolution, bit rate, and codecs, as well as information about its origin, such as the date and time it was created, and the device or software that was used to create it.
