  26 <p class="p3">"Filter" is an <i>abstract class</i> - in other words, a class that you do not use directly. Instead, use one of its subclasses. Many common filters inherit from this abstract class, including <a href="Filters/LPF.html"><span class="s2">LPF</span></a>, <a href="Filters/HPF.html"><span class="s2">HPF</span></a>, <a href="Filters/MoogFF.html"><span class="s2">MoogFF</span></a>, <a href="Filters/Ringz.html"><span class="s2">Ringz</span></a>, <a href="Synth control/Integrator.html"><span class="s2">Integrator</span></a>, <a href="Filters/Median.html"><span class="s2">Median</span></a>, <a href="Filters/LeakDC.html"><span class="s2">LeakDC</span></a>... and many more.</p>

  31 <p class="p3">The Filter class also provides a simple way to visualise the frequency-wise effect of applying a filter:</p>
