<em>Panning</em> is the process of distributing 1 or more signals
<strong>Panning</strong> is the process of distributing 1 or more signals
across a series of outputs so that the listener will have the
experience of them coming from a particular "space" within the
experience of them coming from a particular point or area of the
overall listening field.

It is used to create a sense of space and/or a sense of motion in an
audio mix. You can spread out different signals acros the space, and
make them move within the space over time.

<h2>Types of Panners</h2>

it has dedicated panners for the following situations:
</p>
<ul>
<li>1 signal distributed to 2 outputs (the "mono" panner)</li>
<li>2 signals distributed to 2 outputs (the "stereo" panner)</li>
<li>N signals distributed to N outputs (the "vbap" panner)</li>
<li>1 signal distributed to 2 outputs (the mono panner)</li>
<li>2 signals distributed to 2 outputs (the stereo panner)</li>
<li>N signals distributed to M outputs (the VBAP panner)</li>
</ul>

Even for each of these cases, there are many different ways to
implement panning. Ardour currently offers just one solution to each
of these situations, but in the future will offer more.

<h2>Panning is not Balance</h2>
<p>
If you are used to the "balance" control found on most home music
playback devices, and on many DAWs and audio editors, you may have
gained a particular idea of how "panning" should work. You turn the
knob to the left, and the signal in the right speaker gradually
vanishes as you do. You turn it back to the right, and the signal in
the left speaker vanishes in the same way.
</p>
<p>
This is <strong>not</strong> panning. It does not alter the placement either the
left or right signal, but rather is just a different term for
"independent gain control". What is actually happening is that as
you move the balance control left of center, it reduces the volume
of the right channel towards zero, but leaves the left signal at
normal volume. When you move it back to right of center, it reduces
the volume of the left channel toward zero, and leaves the right
channel at normal volume. When the control is exactly in the middle,
both channels are at normal volume.
</p>
<p>
The panners in Ardour control the distribution of at least one
signal across at least 2 outputs. Ardour does not (currently) come
with a balance control. Many people would like to see one.
In addition to the panners, Ardour has a stereo balance control for subtle
corrections to an existing stereo image.
