Dust randomly triggers Decay to create an exponential decay envelope
for the WhiteNoise input source.  The input is mixed with the delay.

> g_01 =
>     let t = dust 'α' AR 1
>         n = whiteNoise 'β' AR
>         d = decay t 0.5 * n * 0.3
>     in bufDelayC 0 d 0.2 + d

Mouse control for delay time

> g_02 =
>     let t = dust 'α' AR 1
>         n = whiteNoise 'β' AR
>         d = decay t 0.3 * n
>         x = mouseX KR 0.0 0.2 Linear 0.1
>     in d + bufDelayC 0 d x
