<h3 id="example-5-controlling-the-volume">Example 5: Controlling the volume</h3>
<p>Let's see an example where we combine three primitives:
  <code>_</code>, <code>0.1</code> and <code>*</code>,
with two composition operators:
<code>,</code> and <code>:</code>.</p>
<p>The idea here is to lower the volume of the incoming signal to one tenth of its initial value. This is done by multiplying the incoming signal by <code>0.1</code>:</p>
