PulseAudio is a sound server for Linux and other Unix like operating
systems.

PulseAudio makes possible to:
* transfer audio to a different machine
* change the sample format or channel count and mixing several
sounds into one
* combine multiple sound cards to one (with sample rate adjustment)
* simple command line interface for reconfiguring the daemon while
running

PulseAudio provides:
* better low latency behaviour
* support for more than one sink/source
* an extensible plugin architecture (by loading dynamic loadable
modules with dlopen())
* a completely asynchronous C API
* flexible, implicit sample type conversion and resampling
* "zero-copy" architecture
* module autoloading
* very accurate latency measurement for playback and recording.
* client side latency interpolation
* C library to enable embedding into other software
