normalize~ Scale a signal based on its maximum amplitude Scale a signal based on its maximum amplitude. normalize~ performs real-time normalization of its input by multiplying each input sample value by a scaling factor Ñ computed as the maximum output value (sent either as a signal or a float in the right inlet) over the maximum signal input value received thus far. You can change the maximum input value with the reset message or with a float in the left input. If no argument follows "reset" the new maximum input value (and the initial maximum input value) is 0.000001
