JRiver Media Center  JRiver Media Center is a multimedia application that allows the user to play and organize various types of media on a computer running Windows, macOS, or Linux operating systems. JRiver Media Center is a "jukebox"-style media player, like iTunes, which usually uses most of the screen to display a potentially very large library of files. Regular (usually daily beta) builds are posted on the Media Center Interact forum implementing requested features and fixing reported bugs. The forum has an active user community, with more than 25,000 users as of 2011. Also available for JRiver Media Center are an Audioscrobbler plugin, and G-Force, a popular visualisation. It can also rip and burn CDs. Media Center also supports static and dynamic playlists. The system also allows users of intelligent powered loudspeakers to use paired devices in stereo configuration, previously only possible without Jriver. JRiver Media Center organizes files using Media Libraries; these are effective databases. Media Center can support multiple libraries. Information relating to media is imported into the library, including meta data for media files and the path to the media files. The media files themselves are not contained in the database, but cataloged within the libraries. Version 12 of JRiver Media Center added support for auto-importing of media, whereby JRiver Media Center continually watches designated directories for changes in media. If a new file is dropped into the directory, JRiver Media Center will add the file to its library. Each library can contain any type of media, video, audio, images etc.  View Schemes are the main way to browse through files in Media Center. Views can be created which help users see different parts of their library; these are effectively the same as database views. They are based on using metadata as criterion for creating a filtered list of files. The view system is very powerful and fully customizable. For example, a view could be made which shows only audio files in MP3 format which are longer than 3 minutes, or images taken in Africa in the year 2006. For ease of use, several default views exist which show files of a specified type only, including: audio, images, or video. Various view items, or panes, can be aligned to the top, left, right, or moved in drop-down menus, that can be used to further filter results. For example, one of the default views, artist/album, allows selecting a specific artist or album, or both, and shows files from that album or artist only.
