RM vs AAC:
Name RM AAC
Full name RealMedia Advanced Audio Coding
File extension .rm, .rmvb .aac
MIME application/vnd.rn-realmedia audio/aac
Developed by RealNetworks Bell Labs, Fraunhofer Institute etc.
Type of format Multimedia container format Audio compression format
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. Advanced Audio Coding (AAC) is an audio coding standard for lossy digital audio compression. Designed to be the successor of the MP3 format, AAC generally achieves better sound quality than MP3 at similar bit rates. AAC has been standardized by ISO and IEC, as part of the MPEG-2 and MPEG-4 specifications.
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. AAC supports inclusion of 48 full-bandwidth audio channels in one stream plus 16 low frequency effects channels, up to 16 "coupling" or dialog channels, and up to 16 data streams. The quality for stereo is satisfactory to modest requirements at 96 kbit/s in joint stereo mode; however, hi-fi transparency demands data rates of at least 128 kbit/s.
