DBMix is a software DJ mixing system for digital audio. DBMix allows a user to output multiple simultaneous audio streams on a single sound device, and to transform/modify each stream independently. There are five main components to DBMix:

1. Fourier Synthesis Daemon - this is a daemon application
   that handles adding multiple data streams into a single data stream for
   output, allowing you to play multiple songs simultaneously with a single
   soundcard. Each data input stream to the fourier synthesis daemon is refered to as a "channel", because this is the name given to each input to an analog DJ Mixer.
   
2. Clients - responsible for creating input to the system, and writing the data to a dbfsd channel. Example generators are xmms, mpg123, and sox.
   
3. DBAudiolib - this is the client interface API to dbmix.
   It provides transparent format conversion and pitch/speed control.
   
4. Mixer - the mixer is the user interface to the DBMix system. It allows a single interface to control all input channels. An example of a mixer is the DBMixer application. DBMixer allows the user to mute, change volume, cue, and crossfade inputs
   
5. Peripherals - hardware devices that you can use
   to control aspects of dbmix. See the section on exmixer below for and
   example.
