Anyone whoÕs interested in hearing sound on the Net and doesnÕt already have RealPlayer installed should get it straight away, because itÕs an essential bit of kit for browsing the Web. 
Increasing numbers of Webmasters are realising that itÕs easy to convert sound files into the RealAudio format. ItÕs not just about music, either. You can listen to talk radio or live news broadcasts, view movie trailers and even eavesdrop on crank phone calls on the Net. But in most cases youÕll need to have RealPlayer on your computer.
