Have you tried using vlc?

vlc provides for pretty sophisticated routing across multiple transports, and
with data transformations. All of this can be specified using a slightly
arcane, but relatively understandable command-line syntax (vlc can be run
without a GUI at all).

For instance, the following command reads raw audio data from stdin and
broadcasts RTP over the network:

vlc --intf dummy - :no-video :sout=#std{access=udp,dst=239.0.0.0:15000}

But things can be a lot more sophisticated than that! Various transformations
can be strung together like UNIX pipes, all within vlc's processing framework.
You just modify the conversion string in the command to further process the
stream, or even fork it to push audio data to multiple destinations.
