maxabs — Produces a signal that is the maximum of the absolute values of any number of input signals.


The maxabs opcode takes any number of a-rate or k-rate signals as input (all of the same rate), and outputs a signal at the same rate that is the maximum of all of the inputs. It is identical to the max opcode except that it takes the absolute value of each input before comparing them. Therefore, the output is always non-negative. For a-rate signals, the inputs are compared one sample at a time (i.e. maxabs does not scan an entire ksmps period of a signal for its local maximum as the max_k opcode does).


amax maxabs ain1 [, ain2] [, ain3] [, ain4] [...]
kmax maxabs kin1 [, kin2] [, kin3] [, kin4] [...]


ain1, ain2, ... -- a-rate signals to be compared.

kin1, kin2, ... -- k-rate signals to be compared.
