RM vs MP3:
|Full name||RealMedia||MPEG-1 or MPEG-2 Audio Layer III|
|File extension||.rm, .rmvb||.mp3|
|MIME||application/vnd.rn-realmedia||audio/mpeg, audio/MPA, audio/mpa-robust|
|Developed by||RealNetworks||Fraunhofer Institute|
|Type of format||Multimedia container format||Digital audio|
|Introduction||RealMedia is a proprietary multimedia container format created by RealNetworks. Its extension is ".rm". It is typically used in conjunction with RealVideo and RealAudio and is used for streaming content over the Internet. Typically these streams are in CBR, but a container for VBR streams, named RMVB, has been developed.||MPEG-1 or MPEG-2 Audio Layer III, more commonly referred to as MP3, is an audio coding format for digital audio which uses a form of lossy data compression. It is a common audio format for consumer audio streaming or storage, as well as a de facto standard of digital audio compression for the transfer and playback of music on most digital audio players.|
|Technical details||Support of RealMedia is available in a few multimedia players for different architectures/platforms, including RealPlayer, the Real Alternative codec pack and the open source DAP firmware Rockbox.||The use of lossy compression is designed to greatly reduce the amount of data required to represent the audio recording and still sound like a faithful reproduction of the original uncompressed audio. An MP3 file that is created using the setting of 128 kbit/s will result in a file that is about 1/11 the size of the CD file created from the original audio source.|
