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.

NAME

       record - records *.wav files

SYNOPSIS

       record [ options ]

DESCRIPTION

       record records *.wav files in CD quality (i.e. 44100 Hz, 16bit, stereo).  It has a input level meter, which might be useful for sound trou-
       ble shooting (check if the mixer settings ok for recording from the TV card etc.)

OPTIONS

       -h     display help text

       -o file
	      basename for the output file(s), a number and the .wav extension are added by record.  Default is "record".

       -i dev mixer control.  This should be the one where you can adjust the record level for your audio source.  Default is "line".	"mic"  and
	      "igain" are good candidates too.	Best way to figure is to start your favorite mixer tool and check out which one works ...

       -m dev set mixer device.  Default is "/dev/mixer".

       -d dev set audio device.  Default is "/dev/dsp".

       -r rate
	      set sample rate.	Default is 44100.

       -p sec peak  seconds  (number  of  seconds which should be scanned for the volume maximum).  This affects both peak level display and level
	      triggered recording (see below).	Default is 1.5 seconds.

       record can also be used non-interactive:

       -c     enable console (non-interactive) mode.

       -v     be verbose (console mode only).

       -t mm:ss
	      Limit the record time (console mode only).  By default record records until stopped by a signal (by typing ^C for example).

       -s size
	      Limit the file size (console mode only).	record will continue with a new file once the limit is reached.

       -n num Limit the file count (console mode only).  record will stop recording after num files.

       -l     Enable level triggered recording (console mode only) with the default trigger level (1000).

       -L level
	      Enable level triggered recording with the specified trigger level.

       If level triggered recording is active, record will start and stop recording depending on the signal strength.  Recording will  be  started
       if  the signal strength is above the trigger level (1000/32768 => around 3%).  Recording will be stopped if the signal is below the trigger
       level for some time (1.5 seconds by default, the -p switch changes this).
