#X text 107 614 The sah~ object accepts two signals. The left signal
is the "input" and the right signal is the "control." When the control
makes a transition from being at or below the trigger value to being
above the trigger value \, the input is sampled and its current value
is output until another control transition occurs and the input is
sampled again. The default threshold value is 0 \, but can be specified
via a float in the left inlet or as an argument to sah~.;
