class:: DC
summary:: Create a constant amplitude signal
related:: Classes/LeakDC
categories::  UGens>Generators>Single-value

Description::

This UGen simply outputs the initial value you give it.

classmethods::

method::ar, kr

argument::in
constant value to output, cannot be modulated, set at initialisation time

examples::
code::
//won't work (the output is 0.5*0.0), which is why we need the DC UGen!
{0.5}.play

//constantly zero
{DC.ar(0.0) }.play;


//DC offset; will click on start and finish
{DC.ar(0.5) + SinOsc.ar(440,0,0.1) }.play;


//test - note the transient before LeakDC adapts and suppresses the offset
{LeakDC.ar(DC.ar(0.5))}.play;
