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  devel‐
        oped,  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.   Obvi‐
        ously,  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 single 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  dis‐
               abled.)
 
        -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
               channels 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 informa‐
               tion.)
 

FILES

        /tmp/chn_comm
               Pipe to input channel n.  Direct use of the pipes is dep‐
               recated, use dbcat instead.  The pipes expect audio input
               in unsigned 16bit PCM format at 44.1kHz.
        dbcat(1), dbin(1), dbmixer(1), dbmix(7).
