<h2>Performance</h2>
<p>
This opcode can be used for monitoring the output signal from csound. It should not be used for processing the signal further.
</p>
<p>
See the entry for the <a class="link" href="fout.html" title="fout"><em class="citetitle">fout</em></a> opcode for an example of usage of <span class="emphasis"><em>monitor</em></span>.

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