Stereo Panner

+

+The default stereo panner distributes 2 inputs to 2 outputs. Its +behaviour is controlled by two parameters, width and position. The +default settings for the stereo panner +are width=100%>, position=center (L=50%, +R=50%). This panner assumes that you have 2 uncorrelated, +independent signals that you wish to distribute to two outputs. +

+
+

+ With the default 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. +

+
+

Stereo Panner User Interface

+ + + +

+ The panner user interface consists of 3 elements, divided between + the top and bottom half. Click and/or drag in the top half to + control position; click and/or drag in the bottom half to control + width (see below for details).

-The stereo panner distributes 2 inputs to 2 outputs. Its behaviour is -controlled by two parameters, width -and position (the latter could also be referred to as -"direction", or "azimuth" without loss of accuracy). +

+ In the top half is the position indicator, which shows where the + center of the stereo image is relative to the left and right + edges. When this is the middle of the panner, the stereo image is + centered between the left and right outputs. When it all the way to + the left, the stereo image collapses to just the left speaker. +

+

+ In the bottom half are two signal indicators, one marked "L" and the + other "R". The distance between these two shows the width of the + stereo image. If the width is reduced to zero, there will only be a + single signal indicator marked "M" (for mono), and whose color will + change to indicate the special state.

-The default settings for the stereo panner -are width=100%, position=center. 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. + It is possible to invert the outputs (see below) so that whatever + would have gone to the right channel goes to the left and vice + versa. When this happens, the entire movable part of the panner + changes color to indicate clearly that this is the case.

Position vs. L/R

+ +

+ Although the implementation of the panner uses the "position" + parameter, when the user interface displays it numerically, it shows a pair of numbers that + will be familiar to most audio engineers. +

+ + + + + + + + +
PositionL/REnglish
0L=50% R=50%signal image is midway between + left and right speakers
-1L=100% R=0%signal image is entirely + at the left speaker
1L=0% R=100%signal image is entirely + at the right speaker
+ +

+One way to remember this sort of convention is that the middle of the +USA is not Kansas, but "Los Angeles: 50% New York: 50%". +
