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

<h2>Description</h2>
<p>
The <span class="emphasis"><em>maxabs</em></span> 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 <span class="emphasis"><em>max</em></span> 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. <span class="emphasis"><em>maxabs</em></span> does not scan an entire ksmps period of a signal for its local maximum as the <span class="emphasis"><em>max_k</em></span> opcode does).
