SpatioScope | SuperCollider 3.13.0 Help

Description

SpatioScope has a layout of speaker positions in 2D space, and shows the volume levels at each speaker's location.( s.options.numOutputBusChannels = 4; s.reboot; // quick first example: z = SpatioScope.new; // default is 4 speakers // 4 chans of sound, randomly panning between { LFDNoise3.ar([2, 3, 5, 8] * 1000) * LFNoise2.kr([5, 8, 13, 21] * 0.1).max(0); }.play; // SpatioScopes survive cmd-period thisProcess.stop; x = { SinOsc.ar(100) * \amp.kr(0.2) }.play; x.set(\amp, 1); z.redLevel = 0.99; z.redLevel = 1.0; x.set(\amp, 1.1); x.free; { PanAz.ar(4, ClipNoise.ar, LFSaw.kr(SinOsc.ar(0.03) * 2)) }.play; // stop and start by hand z.stop; z.start; // hide also stops it z.hide; // show also starts it z.show; // shift the bus channels by an offset - listen to out channels 4-7 z.busOffset_(8); s.scope(4, 8); // play something on these to check { Decay.ar(Impulse.ar(1, [1, 2, 3, 4] / 4), 0.01) }.play(outbus: 8); // try changing the decayTime z.set(\decayTime, 0.4); z.set(\decayTime, 1); ~lfo = { SinOsc.kr([1, 2, 3, 4] / 4).range(0, 0.8) }.play; s.scope(4, rate: \control); z.krListen(0); // back to audio out z.arListen(0, 4);

Class Methods

.group

get and set the parent group of the listening synths (to set a spcific order, or to load-balance with supernova)

.new

Arguments:

locations	locations in space of [-1, 1] for x and y
server	which server to watch
parent	which window or view to show the spatioScope on
bounds	view bounds for the spatioScope
busOffset	busOffset at which spatioScope begins to listen

.grid

create a spatioScope with a grid of locationsz = SpatioScope.grid(4,6);

Arguments:

numx	number of locations per row
numy	number of locations per column
server	which server
parent	which window or view to show the spatioScope on
bounds	view bounds for the spatioScope

.gridPos

create a grid of locations to use in a spatioScopeSpatioScope.gridPos(2, 4).printAll; SpatioScope.gridPos(4, 6).printAll;

.ring

create a spatioScope with a ring of locationsz = SpatioScope.ring(5); // 1 is right z = SpatioScope.ring(8); // more speakers z = SpatioScope.ring(8, 0.8); // ring radius z = SpatioScope.ring(5, 0.5, 0.5pi); // radius, rotate location clockwise -> bottom z = SpatioScope.ring(6, 0.5, pi); // radius, rotate location clockwise -> left z = SpatioScope.ring(7, 0.5, 1.5pi); // radius, rotate location clockwise -> top // a ring + e.g. subwoofer in center z = SpatioScope(SpatioScope.ringPos(6, 0.8, pi) ++ [0@0]);

Arguments:

num	number of locations
radius	radius of ring
angleOffset	clockwise angle offset for location 1: 0 is right, 0.5pi is bottom, etc.
server	which server
parent	which window or view to show the spatioScope on
bounds	view bounds for the spatioScope

.ringPos

create an array of locations that form a ringSpatioScope.ringPos(5); SpatioScope.ringPos(8);

.rings

create a spatioScope with locations that form concentric ringsz = SpatioScope.rings([8, 4]); // 2 rings, outer ring is lower channels z = SpatioScope.rings([8, 4], nil, -0.5pi); // 1 on top z = SpatioScope.rings([8, 4], [0.4, 0.75]); // low chan numbers inside z = SpatioScope.rings([12, 8, 4], nil, -0.5pi); // 3 rings // roughly the angle offsets for IEM CUBE z = SpatioScope.rings([12, 8, 4], nil, (-0.5 + [0, 0.125, 0.25]) * pi); // roughly the Animax Dome setup in Bonn z = SpatioScope.rings([16, 12, 8, 4], nil, (-0.5 + [0.0625, 0.083, 0.125, 0.25]) * pi); // test with several sources { { Ringz.ar(Dust2.ar(5), exprand(300, 10000), exprand(0.03, 0.1)) }.dup(z.numChannels) }.play;

Arguments:

nums	number of speakers in each ring
radii	the radii of each ring (nil distributes the radii between 0 and 1)
angleOffsets	the angle offsets for each ring; if a single value, it applies to all rings.
server	which server
parent	which window or view to show the spatioScope on
bounds	view bounds for the spatioScope
