## minabs

minabs — Produces a signal that is the minimum of the absolute values of any number of input signals.

## Description

The minabs 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 minimum of all of the inputs. It is identical to the min 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. minabs does not scan an entire ksmps period of a signal for its local minimum as the max_k opcode does).

## Syntax

    amin minabs ain1 [, ain2] [, ain3] [, ain4] [...]

    kmin minabs kin1 [, kin2] [, kin3] [, kin4] [...]

## Performance

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

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