<h2>Stereo Panner</h2>
|
||
|
|
||
|
<p>
|
||
|
The stereo panner distributes 2 inputs to 2 outputs. Its behaviour is
|
||
|
controlled by two parameters, <code>width</code>
|
||
|
and <code>position</code> (the latter could also be referred to as
|
||
|
"direction", or "azimuth" without loss of accuracy).
|
||
|
</p>
|
||
|
|
||
|
<p>
|
||
|
The default settings for the stereo panner
|
||
|
are <code>width=100%</code>, <code>position=center</code>. With these
|
||
|
values it is not possible to alter the position, since the width is
|
||
|
already spread entirely across both outputs. To alter the position,
|
||
|
you must first reduce the width.
|
||
|
</p>
|
||
|
|
||
|
<h4>Using the mouse</h4>
|
||
|
|
||
|
<p>Mouse operations in the upper half of the panner adjust the position
|
||
|
parameter, constrained by the current width setting.
|
||
|
</p>
|
||
|
|
||
|
<p>Mouse operations in the lower half of the panner adjust the width
|
||
|
parameter, constrained by the current position setting.
|
||
|
</p>
|
||
|
|
||
|
|
||
|
<p>To change the position smoothly, press the right button and drag
|
||
|
within the top half of the panner, then release. The position will
|
||
|
be limited by the current width setting.

<h4>Keyboard bindings</h4>
|
||
|
|
||
|
When the pointer is within a stereo panner user interface, the following
|
||
|
keybindings are available to operate on that panner:
|
||
|
|
||
|
<dl>
|
||
|
<dt><key>↑</key></dt>
|
||
|
<dd>increase width by 1°</dd>
|
||
|
<dt><key class="mod1">↑</key></dt>
|
||
|
<dd>increase width by 5°</dd>
|
||
|
<dt><key>↓</key></dt>
|
||
|
<dd>decrease width by 1°</dd>
|
||
|
<dt><key class="mod1">↓</key></dt>
|
||
|
<dd>decrease width by 5°</dd>
|
||
|
<dt><key class="mod2">↑</key></dt>
|
||
|
<dd>reset width to 180° (100%)</dd>
|
||
|
<dt><key>←</key></dt>
|
||
|
<dd>move position 1° to the left</dd>

<h4>Using the scroll wheel</h4>
|
||
|
|
||
|
When the pointer is within a stereo panner user interface, the scroll
|
||
|
wheel may be used as follows:
|
||
|
|
||
|
<dl>
|
||
|
<dt>scroll left</dt>
|
||
|
<dd>increase width by 1°</dd>
|
||
|
|
||
|
<dt><key class="mod1">scroll left</key></dt>

|
||
|
|
||
|
<dt>scroll left</dt>
|
||
|

|
||
|
|
||
|
<dt><key class="mod1">scroll left<key></dt>
|
