<p>pan2 —
Distribute an audio signal across two channels.
</p>
</div>
<div class="refsect1">
<a id="idm281472905914904"></a>
<h2>Description</h2>
<p>
Distribute an audio signal across two channels with a choice of methods.
</p>
</div>
<div class="refsect1">
<a id="idm281472905903480"></a>
<h2>Syntax</h2>
<pre class="synopsis">a1, a2 <span class="command"><strong>pan2</strong></span> asig, xp [, imode]</pre>
</div>
<div class="refsect1">
<a id="idm281472905901272"></a>
<h2>Initialization</h2>
<p>
<span class="emphasis"><em>imode</em></span> (optional) -- mode of the stereo
positioning algorithm. 0 signifies equal power (harmonic)
panning, 1 means the square root method, 2 means simple linear
and 3 means an alternative equal-power pan (based on an UDO). The default value is 0.
</p>
</div>
<div class="refsect1">
<a id="idm281472905899400"></a>
<h2>Performance</h2>
<p>
<span class="emphasis"><em>pan2</em></span> takes an input
signal <span class="emphasis"><em>asig</em></span> and distributes it across two
outputs (essentially stereo speakers) according to the
control <span class="emphasis"><em>xp</em></span> which can be k- or a-rate. A
zero value for <span class="emphasis"><em>xp</em></span> indicates hard left, and
a 1 is hard right.
</p>
</div>
<div class="refsect1">
<a id="idm281472905851032"></a>
<h2>Example</h2>
<p>
Here is an example of the pan2 opcodes. It uses the file <a class="ulink" href="examples/pan2.csd" target="_top"><em class="citetitle">pan2.csd</em></a>.
