<h2>Description</h2>
<p>
Takes a sound file and scales it by applying a gain, either
constant or variable. The scale can be specified as a multiplier,
a maximum or a percentage of 0db.

<h2>Examples</h2>
<p>
</p>
<pre class="programlisting">
<span class="emphasis"><em>scale</em></span> -s -W -F 0.96 -o out.wav sound.wav</pre>
<p>
This creates a new sound file with a constant gain of
0.96. It is particularly useful if the input file is
in floating point format.
