<ul>
<li class="p"><p class="hcp1">Reduces
the level of a (music) signal depending on the level
of a control (mic) signal.</p></li>
<li>Features an exponential attack and decilinear (linear
dB per unit time) recovery for natural sounding fades.</li>
</ul>
<h2>Inputs and Outputs</h2>
<p>The single channel ducker has one audio input for music,
an audio input for the control (microphone) signal, and
one audio output.</p>
<p>The stereo ducker is identical to the single channel
version except that it has 2 audio inputs for music, an
audio input for the control (microphone) signal, and 2
audio outputs. Adjustment of controls has the same effect
on both channels.</p>
<h2>Properties</h2>
<h4>Mic feed to output</h4>
<p>This sends the Mic signal direct to the output for further
mixing elsewhere.</p>
<h2>Control Panel</h2>
<p><img src="Duckercp.JPG" alt="image:duckercp.JPG" title="image:duckercp.JPG" style="border-width: 2px; border-style: solid;
margin-top: 0px; margin-bottom: 0px; margin-left: 0px;
margin-right: 0px;" width="470" height="260" border="2"></p>
<h4>Threshold control</h4>
<ul>
<li class="p"><p>Adjusts the level threshold of the
Mic signal above which <a href="MAINGainMute.htm">gain</a>
reduction of the music signal will take place. Below
this threshold, no gain reduction will take place.</p></li>
</ul>
<h4>Range control</h4>
<ul>
<li class="p"><p>Adjusts how 'deeply' the ducker will
reduce the signal level of the music signal.</p></li>
</ul>
<h4>Duck time control</h4>
<ul>
<li class="p"><p>Adjusts the time it takes for the
ducker to fade the music down when the Mic signal
levels goes above threshold.</p></li>
</ul>
<h4>Hold control</h4>
<ul>
<li class="p"><p>Extends the 'ducked' phase to prevent
'chatter'.</p></li>
</ul>
<h4>Recover time control</h4>
<ul>
<li class="p"><p>Adjusts the time it takes the ducker
to fade the music signal up when the mic signal level
falls below the threshold.</p></li>
</ul>
<h4>Bypass button</h4>
<ul>
<li class="p"><p>Removes the ducker from the signal
path.</p></li>
</ul>
<h4>Gain Reduction meter</h4>
<ul>
<li class="p"><p>Displays the amount of gain reduction
being applied.</p></li>
</ul>
<h2>Notes</h2>
<p><span style="font-weight: bold;">!</span> This object
will cause audible distortion if the Attack and Release
times are too fast since it will be trying to apply dynamic
gain reduction to the instantaneous values of lower frequency
waveforms</p>
