Snd is a sound editor modelled loosely after Emacs. It can accommodate any number of sounds, each with any number of channels. It can be customized and extended using Guile, Ruby, or Forth.
DBFSD(1) General Commands Manual DBFSD(1)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

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.
