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. SEE ALSO

bchunk - CD image format conversion from bin/cue to iso/cdr SYNOPSIS
bchunk [-v] [-p] [-r] [-w] [-s] <image.bin> <image.cue> <basename> DESCRIPTION
bchunk converts a CD image in a ".bin / .cue" format (sometimes ".raw / .cue") to a set of .iso and .cdr tracks. The bin/cue format is used by some non-Unix cd-writing software, but is not supported on most other cd-writing programs. image.bin is the raw cd image file. image.cue is the track index file containing track types and offsets. basename is used for the begin- ning part of the created track files. The produced .iso track contains an ISO file system, which can be mounted through a loop device on Linux systems, or written on a CD-R using cdrecord. The .cdr tracks are in the native CD audio format. They can be either written on a CD-R using cdrecord -audio, or con- verted to WAV (or any other sound format for that matter) using sox. The output type depends on the input type (data is just copied). If the input is in ISO format, the output will be. On the other hand, if the input is raw audio data, the output will be CDR or WAV (the latter if -w is given). It is advisable to edit the .cue file to either MODE2/2352/2048 or MODE2/2352/2324 depending on whether an ISO filesystem or a VCD is desired, respectively. The format itself does not contain this feature and in an ambiguous case it can only guess. OPTIONS
-v Makes binchunker print some more unnecessary messages, which should not be of interest for anyone. -w Makes binchunker write audio tracks in WAV format. -s Makes binchunker swap byte order in the samples of audio tracks. -p Makes binchunker go into PSX mode and truncate MODE2/2352 tracks to 2336 bytes at offset 0 instead of normal 2048 bytes at offset 24. Use this option if input is in PSX mode. -r Makes binchunker output MODE2/2352 tracks in raw format, from offset 0 for 2352 bytes. Good for MPEG/VCD. Use this option if input is in raw format. FILES
image.bin Raw CD image file image.cue TOC (Track index, Table Of Contents) file *.iso Tracks in ISO9660 CD filesystem format. Can be either written on a CD-R using cdrecord, or mounted (on Linux platforms at least) through a loop device ('mount track.iso /mnt/cdrom -o loop=/dev/loop0,blocksize=1024'). *.cdr Audio tracks in native CD audio format. They can be either written on a CD-R using 'cdrecord -audio', or converted to WAV (or any other sound format for that matter) using sox ('sox track.cdr track.wav'). *.wav Audio tracks in WAV format.
