max_k outputs the local maximum (or minimum) value of the incoming <span class="emphasis"><em>asig</em></span> signal, checked in the time interval between <span class="emphasis"><em>ktrig</em></span> has become true twice. <span class="emphasis"><em>itype</em></span> determinates the behaviour of max_k:</p>
<p>
1 - absolute maximum (sign of negative values is changed to positive before evaluation)
</p>
<p>
2 - actual maximum
</p>
<p>
3 - actual minimum
</p>
<p>
4 - calculate average value of <span class="emphasis"><em>asig</em></span> in the time interval
</p>
<p>
This opcode can be useful in several situations, for example to implement a vu-meter.
