final case class DetectSilence(rate: MaybeRate, in: GE, amp: GE = 1.0E-4f, dur: GE = 0.1f, doneAction: GE = doNothing) extends SingleOut with HasSideEffect with Product with Serializable
A UGen which detects whether its input signal falls below a given amplitude for
a given amount of time (becoming "silent"). A silence is detected if the
absolute sample values of the input remain less than or equal to the amp
threshold for a consecutive amount of time given by the dur argument.
A value of 1 is output when this condition is met, and a value of 0 is
output when the condition is not met (i.e. at least one sample occurs in the
input whose absolute value is greater than amp ). Besides, when the output
changes from zero to one, the doneAction is executed (unless it is doNothing
).
A special case is the initial condition of the UGen: It will begin with an
output value of 0 (no silence detected), even if the input signal is below the
amplitude threshold. It is only after the first input sample rising above the
threshold that the actual monitoring begins and a trigger of 1 or the firing
of the done-action may occur.
- in
input signal to be measured.
- amp
minimum amplitude threshold which must be exceeded for the input signal to be considered non-silent. (init-time only)
- dur
The duration in seconds for which the input signal must be continuously smaller than or equal to the threshold to be considered silent. (init-time only)
- doneAction
an action to be performed when the output changes from zero to one (silence detected).
