dbfsd - DB Fourier Synthesis Daemon
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.
-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‐
-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‐
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.
