esd - The Enlightened Sound Daemon DESCRIPTION
Starts up EsounD, which provides a sound mixing server. USAGE
esd [options] -d DEVICE force esd to use sound device DEVICE -b run server in 8 bit sound mode -r RATE run server at sample rate of RATE -as SECS free audio device after SECS of inactivity (-1 to disable) -unix use unix domain sockets instead of tcp/ip -tcp use tcp/ip sockets instead of unix domain -public make tcp/ip access public (other than localhost) -promiscuous start unlocked and owned (disable authenticaton) NOT RECOMMENDED -terminate terminate esd daemon after last client exits -noterminate do not terminate esd daemon after last client exits -nobeeps disable startup beeps -beeps enable startup beeps -trust start esd even if use of /tmp/.esd can be insecure -port PORT listen for connections at PORT (only for tcp/ip) -bind ADDRESS binds to ADDRESS (only for tcp/ip) -v --version print version information Possible devices are: /dev/dsp, /dev/dsp2, etc. FILES

libesd - GNOME Enlightenment Sound Daemon Interface library DESCRIPTION
The libesd library provides access to the Enlightened Sound Daemon (esd). The Enlightened Sound Daemon is launched automatically by libesd if the daemon is not already present. A sockets connection is managed with the daemon by this API. The connection allows sound data to be written to the daemon for playback, or read from the daemon for recording purposes. The daemon will automatically sample an incoming stream from a client to the best format that is supported by the sound device. Therefore, client programs do not have to be concerned with writing platform-specific code for handling sound data. The daemon supports caching. Each sample is given an ID tag, and sound data can then be accessed via this API with this ID tag. If the audio device supports simultaneous record and playback at the same bit resolution, bit rate, and number of channels (in other words, is full duplex), then the daemon and API also supports simultaneous reading and writing from the audio device.
