InGrainBBF granular synthesis with input and user supplied envelope
and Ambisonic panning
*ar(trigger, dur, in, envbuf, azimuth, elevation, rho, mul, add)
trigger - a kr or ar trigger to start a new grain. If ar, grains after the start of the synth are sample accurate.
The following args are polled at grain creation time
dur - size of the grain.
in - the input to granulate
envbuf - a buffer with a stored signal to be used for the envelope of the grain
azimuth - in radians, -pi to pi
elevation - in radians, -0.5pi to +0.5pi
rho - the speaker radius (1 places shound at the radius, <1 within the radius, >1 is outside the radius)
beyond the radius, nothing happens.
Examples:
s.boot;
SynthDef(\in_grain_test, {arg gate = 1, amp = 1, envbuf;
var w, x, y, z;
#w, x, y, z = InGrainBBF.ar(Impulse.kr(10), 0.1, PinkNoise.ar, envbuf,
WhiteNoise.kr.range(-0.25pi, 0.25pi), 0, 1,
EnvGen.kr(
Env([0, 1, 0], [1, 1], \sin, 1),
gate,
levelScale: amp,
doneAction: 2));
Out.ar(0, DecodeB2.ar(4, w, x, y));
}).load(s);
z = Env([0, 1, 0], [1, 1], [10, -10]).asSignal(1024);
s.sendMsg(\b_alloc, b = s.bufferAllocator.alloc(1), 1024, 1, [\b_setn, b, 0, 1024] ++ z)
s.sendMsg(\s_new, \in_grain_test, a=s.nextNodeID, 0, 1, \amp, 0.2, \envbuf, b);
s.sendMsg(\n_set, a, \gate, 0);
s.sendMsg(\b_free, b);
