NAME
       dbfsd - DB Fourier Synthesis Daemon

SYNOPSIS
       dbfsd [options]

DESCRIPTION
       The  audio daemon dbfsd serves as the backend part to the DBMix-project.  It allows to connect several audio streams and combines them into
       one, using high quality Fourier synthesis.  Connections currently transfer data via pipes; a network (socket) connection  method  is  being
       developed, but not yet included.  Use dbcat to push audio streams into dbfsd.  The mixer settings are controlled via dbmixer.

       Dbfsd  actually can handle two different output destinations: one is the master device, usually used for the main output; the second one is
       referred to as the cueing device, which is handy for so-called pre-fade listening.  That is, one can check the  starting  position  of  the
       next  song,  or	adjust	its  pitch  before  sending it to the main output.  Obviously, for stereo output to both the master and the cueing
       device, two sound cards (or a sound card with two distinct output channels) are needed.	The -e switch offers a way to cue with only a sin-
       gle sound card, but output is reduced to mono streams.

OPTIONS
       -a dev Set master output device to dev.	(Default: /dev/dsp.)

       -b dev Set cue output device to dev.  (Default: /dev/dsp2.)

       -c     Enable cue output.  (Default: cueing disabled.)

       -d     Print out debug messages to console.  (Default: debugging disabled.)

       -e     Output  cue  as left channel of master out.  This option also enables cue output even if -c is not set.  (Default: cue to both chan-
	      nels of cue output device.)

       -h     Print summary of available options.

       -n max Allow at most max input channels.  (Default: 4.)

       -o     Send master output to stdout.  (Default: send output to master output device.)

       -r n   Set number of OSS output fragments to n.	Decreasing this number will reduce latency between, say, starting dbcat, and  hearing  the
	      results of that action.  Too low a value, however, will results in drop-outs in the stream.  This value can also be adjusted via the
	      preferences dialog in the dbmixer application.  (Default: 128.)

       -s n   Set number of input channels that should be created as sockets to n.  (Default: 0.)

       -v     Print version information.  (Default: no version information.)

FILES
       /tmp/chn_comm
	      Pipe to input channel n.	Direct use of the pipes is deprecated, use dbcat instead.  The pipes expect audio input in unsigned  16bit
	      PCM format at 44.1kHz.
