PanAz | SuperCollider 3.12.2 Help

Class Methods

PanAz.ar(numChans, in, pos: 0.0, level: 1.0, width: 2.0, orientation: 0.5)

PanAz.kr(numChans, in, pos: 0.0, level: 1.0, width: 2.0, orientation: 0.5)

Arguments:

numChans	Number of output channels.
in	The input signal.
pos	pan position (`kr` or `ar`). Channels are evenly spaced over a cyclic period of `2.0` in pos with `0.0` equal to channel zero and `2.0/numChans` equal to channel 1, `4.0/numChans` equal to channel 2, etc. Thus all channels will be cyclically panned through if a bipolar sawtooth wave from `-1` to `+1` is used to modulate the pos.
level	A control rate level input.
width	The width of the panning envelope. Nominally this is `2.0` which pans between pairs of adjacent speakers. Values greater than `2` will spread the pan over greater numbers of speakers. Values less than `1` will leave silent gaps between speakers.
orientation	Should be `0` if the front is a vertex of the spanning polygon. The first speaker will be directly in front. Should be `0.5` if the front bisects a side of the spanning polygon. Then the first speaker will be the one left of center.

Five channel circular panning with first channel on the left( { PanAz.ar( numChans: 5, in: ClipNoise.ar(0.1), pos: LFSaw.kr(MouseX.kr(0.2, 8, 'exponential')), level: 0.5, width: 3, orientation: 0.5 ); }.scope )

Comparison to Pan2

Despite a certain similarity, Pan2 and PanAz with 2 channels behave differently.// one full cycle for PanAz: from -1 to 1 { PanAz.ar(2, DC.ar(1), Line.ar(-1, 1, 0.1), orientation: 0) }.plot(0.1) // comparing with Pan2 { Pan2.ar(DC.ar(1), Line.ar(-1, 1, 0.1)) }.plot(0.1) // to create one full cycle for Pan2, move from 1 to -1 and back to 1 { Pan2.ar(DC.ar(1), EnvGen.ar(Env([1, -1, 1], [0.05, 0.05]))) }.plot(0.1)

The same in one plot window:( { [ PanAz.ar(2, DC.ar(1), Line.ar(-1, 1, 0.1), orientation: 0), Pan2.ar(DC.ar(1), Line.ar(-1, 1, 0.1)), Pan2.ar(DC.ar(1), EnvGen.ar(Env([1, -1, 1], [0.05, 0.05]))) ].flat; }.plot(0.1) )

In other words, while Pan2 needs a position change of 2 from channel 0 to 1{ Pan2.ar(DC.ar(1), Line.ar(-1, 1, 0.1)) }.plot(0.1) // we need a position change of 1 in PanAz: { PanAz.ar(2, DC.ar(1), Line.ar(0, 1, 0.1), orientation: 0) }.plot(0.1)

In one plot window:( { [ Pan2.ar(DC.ar(1), Line.ar(-1, 1, 0.1)), PanAz.ar(2, DC.ar(1), Line.ar(0, 1, 0.1), orientation: 0) ].flat }.plot(0.1) )
