Source code for the fixed-point AAC decoder is
available in the public source at
datatype/aac/codec/fixpt/decoder.

Source code for the ra8lbr codec is available 
once the "Real Format Source Code Porting and Optimization License"
is executed. See here:

https://helixcommunity.org/licenses/request

for more detail.

Other codecs (sipro, RealAudio 8 High BitRate, RealAudio Lossless) are
available in binary distribution library form. If the dist lib
is not currently available for your platform, it can be compiled
in-house and the dist lib placed in the distribution project.
There is a cost associated with this service, although I
don't know the details.

As far as servers go, Helix servers can serve any kind of
RealAudio codec. I would guess that most Internet radio applications
use ra8lbr for music or sipro for voice.
