(delay-l in maxDelayTime delayTime)
(delay-c in maxDelayTime delayTime)

Simple delay line.  There are three forms, delay-n uses no
interpolation, delay-l uses linear interpolation, delay-c uses cubic
interpolation.  The maximum delay length is set at initialization
time and cannot be extended.

dust randomly triggers decay to create an exponential decay
envelope for the white-noise input source.
