RSound is a simplistic and lightweight framework for networked TCP/IP audio. It is designed to be very simple to implement, and to work well with music and video players. A librsound is supplied. It is not designed for low latency audio (games), and lets the sound backend take care of sound mixing. It supports POSIX-compliant systems (including cygwin). It includes audio output support for ALSA, OSS, libao, and PortAudio.
