summary:: Stereo signal balancer
related:: Classes/LinPan2, Classes/Pan2, Classes/Pan4, Classes/PanAz
categories:: UGens>Multichannel>Panners
Description::
Equal power panning balances two channels. By panning from left (pos=-1) to right (pos=1) you are decrementing the level of the left channel from 1 to 0 taking the square root of the linear scaling factor, while at the same time incrementing the level of the right channel from 0 to 1 using the same curve. In the center position (pos=0) this results in a level for both channels of 0.5.sqrt (~=0.707 or -3dB). The output of Balance2 remains a stereo signal.
classmethods::
private:: categories
method::ar, kr
argument::left
channel 1 of input stereo signal
argument::right
channel 2 of input stereo signal
argument::pos
pan position, -1 is left, +1 is right
argument::level
a control rate level input.
Examples::
code::
// a stereo signal, both channels at 0dB
{[SinOsc.ar(440), SinOsc.ar(440)]}.play
// using Balance on a stereo signal with the position parameter at 0, effectively the same sound but both channels at -3dB
{Balance2.ar(SinOsc.ar(440), SinOsc.ar(440), 0)}.play
// pan sweep from left to right
{Balance2.ar(SinOsc.ar(440), SinOsc.ar(1000), Line.kr(-1,1,5))}.play
// other examples
{Balance2.ar(LFSaw.ar(44),Pulse.ar(33),FSinOsc.kr(0.5), 0.1) }.play;
{var source; source= SinOsc.ar([440,550]); Balance2.ar(source[0],source[1],LFNoise0.kr(4),0.3) }.play;
