<h2>Examples</h2>
<p>
The default values are
</p>
<pre class="programlisting">
<span class="emphasis"><em>mixer</em></span> -s -otest -F 1.0 -S 0</pre>
<p>
For example
</p>
<pre class="programlisting">
<span class="emphasis"><em>mixer</em></span> -F 0.96 in1.wav -S 300 -2 in2.aiff -S 300 -^4 1 in3.wav -o out.wav</pre>
<p>
This creates a new sound file with a constant gain of
0.96 from in1.wav with the second channel of in2.aiff
mixed in after 300 samples and channel 4 of in3.wav
outpout as channel 1 after 300 samples.
