dbcat

NAME

dbcat - Send audio data to DB Fourier Synthesis daemon

SYNOPSIS

dbcat [options]

DESCRIPTION

The dbcat tool provides a simple means to feed dbfsd with audio data. Both programs are part of the DBMix project, a digital audio mixing system. dbcat takes input data from its standard input only, and is therefore usually used in a pipe with some other sound generating program.

OPTIONS

-8

Input data comprises of PCM-coded 8bit unsigned samples. (Default: 16bit signed samples.)

-c n

Connect to channel n of dbfsd. (Default: first channel available.)

-d

Print out debug messages to console. (Default: debugging disabled.)

-h

Print summary of available options.

-m

Input data is a mono stream. (Default: interleaved stereo stream.)

-r rate

Input data is sampled at rate Hertz. (Default: 44100Hz.)

-v

Print version information. (Default: no version information.)

-S

Produce an endless stream of blank audio data (silence). Any input data is dropped. This mode provides a dummy source useful for testing and debugging. (Default: pass on input data.)

EXAMPLES

mpg321 -s test.mp3 | dbcat

Sends a 16bit/44.1kHz stereo audio stream decoded from test.mp3 off to dbfsd.
