class:: Pan2
summary:: Two channel equal power pan.
related:: Classes/Balance2, Classes/LinPan2, Classes/Pan4, Classes/PanAz
categories:: UGens>Multichannel>Panners
Description::
Two channel equal power panner. Pan2 takes the square root of the linear scaling factor going from 1 (left or right) to 0.5.sqrt (~=0.707) in the center, which is about 3dB reduction. With linear panning (LinPan2) the signal is lowered as it approaches center using a straight line from 1 (left or right) to 0.5 (center) for a 6dB reduction in the middle. A problem inherent to linear panning is that the perceived volume of the signal drops in the middle. Pan2 solves this.
classmethods::
method::ar, kr
argument::in
The input signal.
argument::pos
Pan position, -1 is left, +1 is right.
argument::level
A control rate level input.
Examples::
code::
// hear the difference, LinPan having a slight drop in the middle...
{ LinPan2.ar(SinOsc.ar(440), Line.kr(-1, 1, 5)) }.play
// ... whereas Pan2 is more smooth
{ Pan2.ar(SinOsc.ar(440), Line.kr(-1, 1, 5)) }.play
// other examples
{ Pan2.ar(PinkNoise.ar(0.4), FSinOsc.kr(2), 0.3) }.play;
