RealAudio <tool, communications> A program from {Real Media} for playing {audio} over the {Internet}, and the {lossy} audio compression format it uses. The system is implemented as a {client/server} architecture. The RealAudio server incorporates an {encoder} which compresses sound into RealAudio files. The client side is a {web browser} {plug-in} or {add-on} (a recent version of {Internet Explorer} apparently has built-in support for RealAudio) which allows the stream of data sent from the server to be uncompressed and output using the normal sound facilities of the computer, such as a {sound card}. A 14.4 {KBps} or better {modem} is required, and a 28.8 KBps connection is recommended for music-quality sound. (http://realaudio.com/). (2001-12-13)
