DC

A UGen that creates a constant signal at a given calculation rate.

===Examples===

// create a silent audio signal
play {
 // Note: Select.ar requires audio-rate input.
 // Therefore, DC can be used to wrap the otherwise
 // incompatible constant zero. In future versions of
 // ScalaCollider, this wrapping will be done
 // automatically, however.
 Select.ar(MouseButton.kr(lag = 0), Seq(DC.ar(0), SinOsc.ar * 0.2))
}
