muroard(1) System User's Manual: muroard muroard(1) NAME
muroard - minimalist sound server for the RoarAudio protocol SYNOPSIS
muroard [OPTIONS]... DESCRIPTION
muRoarD is a sound server supporting the RoarAudio protocol. It is designed to mix the audio data of multiple applications together to send it as a single stream to the soundcard. muRoarD is a minimalist version of such a sound server. It does only implement the very minimum part the the protocol but is very much smaller than the original roard. MISC OPTIONS
-h --help Print a short help and exit. --version Print version information of the daemon and exit. --daemon Bring the server into background after init. On win32 this hides the console window. This only works if used within a Shortcut. --autostandby Start in autostandby mode. --no-autostandby Do not start in autostandby mode. --standby Start in standby mode. --no-standby Do not start in standby mode. AUDIO OPTIONS
-R --rate RATE Set server sample rate. -C --chans CHANNELS Set server number of channels channels. DRIVER OPTIONS
-O --odevice DEV Set output device (sound card). The possible values of this depend on the used driver. SOURCES OPTIONS
-S DEV Set the file or device for the new source. -sC CHANS Sets the number of channels for the source. This is the same as '-sO channels=XXX' for roard. -sB BITS Sets the number of bits for the source. This is the same as '-sO bits=XXX' for roard. -sE CODEC Sets codec for the source. This is the same as '-sO codec=XXX' for roard. NETWORK OPTIONS
--no-listen Disable listen socket. This may be used for example to implement the server type '+fork' but is absolutly useless for normal users. --client-fh FH Add a client via FH. See --no-listen. --bind ADDR Set path/hostname of listen socket. This may be a /path/to/sock for UNIX Sockets or a hostname or address for TCP/IP. Please do not use IP Addresses directly if not needed. Use hostnames. On win32 there is no support for UNIX sockets. Only IP is supported. --port PORT Set port of listen socket. This only applys for TCP/IP sockets and is ignorged for UNIX Sockets. -u --unix Use UNIX Domain listen socket. This is not supported on win32. -t --tcp Use TCP/IP listen socket. -n --decnet Use DECnet listen socket. SEE ALSO
