Pan2

Two channel equal power pan.
Subclasses: LinPan2

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.

Class Methods

*ar (in, pos: 0, level: 1)

*kr (in, pos: 0, level: 1)

Arguments:

in

The input signal.

pos

Pan position, -1 is left, +1 is right.

level

A control rate level input.

Examples

// 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
SynthDef("help-Pan2", { Out.ar(0, Pan2.ar(PinkNoise.ar(0.4), FSinOsc.kr(2), 0.3)) }).play;
