<h2>Syntax</h2>
<pre class="synopsis"><span class="command"><strong>vbapz</strong></span> inumchnls, istartndx, asig, kazim [, kelev] [, kspread]</pre>
</div>
<div class="refsect1" title="Initialization">
<a id="idp50712336"></a>
<h2>Initialization</h2>
<p>
<span class="emphasis"><em>inumchnls</em></span> -- number of channels to write to the ZA array. Must be in the range 2 - 256.
</p>
<p>
<span class="emphasis"><em>istartndx</em></span> -- first index or position in the ZA array to use
</p>
</div>
<div class="refsect1" title="Performance">
<a id="idp50713696"></a>
<h2>Performance</h2>
<p>
<span class="emphasis"><em>asig</em></span> -- audio signal to be panned
</p>
<p>
<span class="emphasis"><em>kazim</em></span> -- azimuth angle of the virtual source
</p>
<p>
<span class="emphasis"><em>kelev</em></span> (optional) -- elevation angle of the virtual source
</p>
<p>
<span class="emphasis"><em>kspread</em></span> (optional) -- spreading of the virtual source (range 0 - 100). If value is zero, conventional amplitude panning is used. When <span class="emphasis"><em>kspread</em></span> is increased, the number of loudspeakers used in panning increases. If value is 100, the sound is applied to all loudspeakers.
</p>
<p>
The opcode <span class="emphasis"><em>vbapz</em></span> is the multiple channel analog of the opcodes like <a class="link" href="vbap4.html" title="vbap4"><em class="citetitle">vbap4</em></a>, working on <span class="emphasis"><em>inumchnls</em></span> and using a ZAK array for output.
