<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>
|
|

|
|
<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>
