RM to M4A: Extract Audio from RM(RealMedia) Video to M4A(MPEG-4 Audio) with River Past Audio Converter, RM2M4A converter, conversion
What is
RM?
A streaming technology developed by RealNetworks
for transmitting live video over the Internet. RealVideo
uses a variety of data compression techniques and works with both normal IP
connections as well as IP Multicast connections.
More information is available on RealNetwork
web site.
To convert RealMedia to other formats with River Past software, please
have Real Alternative installed.
If the RM file was encoded with AC-3 audio, you may also need to install
AC-3 Decoder Filter.
What is
M4A?
Because of its exceptional performance and quality, Advanced
Audio Coding (AAC) is at the core of the MPEG-4,
3GPP and 3GPP2
specifications and is the audio codec of choice for Internet, wireless and digital
broadcast arenas. AAC provides audio encoding that compresses much more efficiently
than older formats, such as MP3,
yet delivers quality rivaling that of uncompressed CD audio.
To encode MPEG-4 audio, you need to have River
Past MPEG-4 Booster Pack in addition to your audio software.
