Test if mplayer can play the stream:
mplayer rtmpt://stream.servername.com/stream/filename.mp3
If this works then you can save the audio in the original format by
using the -dumpaudio option, see manpage of mplayer.
If mplayer does not work (it cannot play certain compressed flash
streams AFAIK) then you can play the stream with the flash application
and capture the sound directly from the ALSA device (instead of going
via speakers and microphone). The trick is to set the correct capture
device; with alsamixer (from package alsa-utils) you can press TAB to
see the capture devices. You probably have to set the capture device to
"Mix" and adjust the volume, then it should be possible to capture what
is played with e.g. the arecord utility. If you prefer GUI applications
to record, audacity should work as well, provided you set the right
capture device.
