<p>out —
Writes audio data to an external device or stream.
</p>
</div>
<div class="refsect1">
<a id="idm281472908269464"></a>
<h2>Description</h2>
<p>
Writes audio data to an external device or stream, either from
audio variables or from an audio array.
</p>
</div>
<div class="refsect1">
<a id="idm281472908257416"></a>
<h2>Syntax</h2>
<pre class="synopsis"><span class="command"><strong>out</strong></span> asig1[, asig2,....]</pre>
<pre class="synopsis"><span class="command"><strong>out</strong></span> aarray</pre>
</div>
<div class="refsect1">
<a id="idm281472908254184"></a>
<h2>Performance</h2>
<p>
Sends audio samples to an accumulating output buffer
(created at the beginning of performance) which serves to
collect the output of all active instruments before the sound is
written to disk. There can be any number of these output units
in an instrument.
</p>
<p>
In the array case each element of the arrary is sent to the
corresponding channel. This provides a way of using many
channels. The nonarray version is limited to 1999.
</p>
<p>
The type (mono, stereo, quad, hex, or oct) should agree
with <a class="link" href="nchnls.html" title="nchnls"><em class="citetitle">nchnls</em></a>. But
as of version 3.50, Csound will attempt to change an incorrect
opcode to agree with <span class="emphasis"><em>nchnls</em></span> statement.

<a id="idm281472908209000"></a>
<h2>Examples</h2>
<p>
Here is an example of the out opcode. It uses the file <a class="ulink" href="examples/out.csd" target="_top"><em class="citetitle">out.csd</em></a>.
