<h2>Syntax</h2>

</div>
<div class="refsect1" title="Initialization">
<a id="idp29584472"></a>
<h2>Initialization</h2>
<p>
<span class="emphasis"><em>islot1</em></span> -- slot where the first analysis was stored
</p>
<p>
<span class="emphasis"><em>islot2</em></span> -- slot where the second analysis was stored
</p>
<p>
<span class="emphasis"><em>kmix</em></span> -- mix value between the two analysis. Should be between 0 and 1. 0 means analysis 1 only. 1 means analysis 2 only. Any value in between will produce interpolation between the filters.
</p>
<p>
<span class="emphasis"><em>lpinterp</em></span> computes a new set of poles from the interpolation between two analysis. The poles will be stored in the current <span class="emphasis"><em>lpslot</em></span> and used by the next <span class="emphasis"><em>lpreson</em></span> opcode.
