happens~ 2-states threshold detector with attack and release times When using noisy sensor data to trigger something, there's often the need of obtaining a steady signal to indicate that the threshold has been exceeded for a determinate amount of time, and viceversa. Happens~ outputs 1 when the input signal has exceeded the threshold for a determinate amount of time. While the signal is under the threshold value, the attack time of the internal envelope follower is the one defined by the user, ad the release time is 0. When the state changes to triggered, the attack time is 0 and the release time is the one specified by the user.
