Real Player is a proprietary audio format developed by Real Networks. It uses a variety of audio codecs, ranging from low-bitrate formats that can be used over dialup modems, to high-fidelity formats for music. It can also be used as a streaming audio format, that is played at the same time as it is downloaded. In the past, many internet radio stations used RealAudio to stream their programming over the internet in real time. In recent years, however, the format has become less common and has given way to more popular audio formats. It is used heavily by the BBC websites, though its use on the site is being phased out.
This one is a personal favorite for me. I always use this to play each and everything either its Audio or Video whether its VCD, DVD, AVI, MKV, Ogg, OGM, 3GP, MPEG-1/2/4, WMV, RealMedia, QuickTime or any other format etc. It lets you play almost everything seamlessly. I haven’t ran into it not being able to play any format of media files.
It got too many options letting you adjust everything you could ever think of starting from Equalizer, Subtitles, audio settings, Video settings, 3D Surround sound, Audio/video Synchronization and much more. Just think of something and you can change it just by your right click.
