pulseaudio is a sound server for Linux and other Unix like operating
systems. It is intended to be an improved drop-in replacement for the
Enlightened Sound Daemon (EsounD). In addition to the features EsounD
provides pulseaudio has:
* Extensible plugin architecture (by loading dynamic loadable
modules with dlopen())
* Support for more than one sink/source
* Better low latency behaviour
* Embedabble into other software (the core is available as C
library)
* Completely asynchronous C API
* Simple command line interface for reconfiguring the daemon while
running
* Flexible, implicit sample type conversion and resampling
* "Zero-Copy" architecture
* Module autoloading
* Very accurate latency measurement for playback and recording.
* May be used to combine multiple sound cards to one (with sample
rate adjustment)
* Client side latency interpolation
