# Short-Description: sound server for audio mixing
# Description:       RoarAudio is a server for audio mixing. Its main purpose is to mix audio from
#                    different clients before sending it to its outputs (for example a soundcard).
#                    It is completely network transparent (UNIX sockets, TCP/IP, DECnet) and
#                    supports many common codecs like Ogg Vorbis, Speex or FLAC.
