What is Enlightened Sound Daemon mean?
In computing, the Enlightened Sound Daemon (ESD or EsounD) was the sound server for Enlightenment and GNOME. Esound is a small sound daemon for both Linux and UNIX. ESD was created to provide a consistent and simple interface to the audio device, so applications do not need to have different driver support written per architecture. It was also designed to enhance capabilities of audio devices such as allowing more than one application to share an open device. ESD accomplishes these things while remaining transparent to the application, meaning that the application developer can simply provide ESD support and let it do the rest. On top of this, the API is designed to be very similar to the current audio device API, making it easy to port to ESD.
ESD will mix the simultaneous audio output of multiple running programs, and output the resulting stream to the sound card.
ESD can also manage network-transparent audio. As such, an application that supports ESD can output audio over the network, to any connected computer that is running an ESD server.
ESD support must be specifically written and added into applications, as ESD does not emulate normal audio hardware APIs. Since ESD has been around for over a decade, earlier than almost any other sound server, a very large number of Unix applications have support for ESD output built-in, or available as add-ons.
ESD was maintained as part of the GNOME project, but as of April 2009, all ESD modules in GNOME have been ported to libcanberra for event sounds or GStreamer/PulseAudio for everything else.
PulseAudio 2.0 completely drops ESounD support.
