Signal Processing in SuperCollider. There are lots of choices for these grains, they might be enveloped sine tones, or tiny extracts of sampled sound: b = Buffer.read(s,Platform.resourceDir +/+ "sounds/a11wlk01.wav"); singrain1=SinOsc.ar(440,0,XLine.kr(1.0, 0.0001, 0.05)); singrain2=FSinOsc.ar(800, 0.0, Line.kr(1.0,0,0.05).squared); sfgrain=(PlayBuf.ar(1,b.bufnum, BufRateScale.kr(b.bufnum)))*EnvGen.kr(Env([0,1,1,0],[0.01,0.01,0.01], -4)); When lots of these microsounds are combined into big swarms, we can make macroscopic soundscapes. There are lots of choices for these grains, they might be enveloped sine tones, or tiny extracts of sampled sound: b = Buffer .read (s, Platform .resourceDir +/+ "sounds/a11wlk01.wav" ); An illustration of granular synthesis, using SuperCollider’s TGrains unit-generator. in gui granular synthesis wavesets wavesetsevent. @lukaprincic:matrix.org. // Boot the server s.boot; // Load an audio file s.sendMsg(\b_allocRead, 10, “sounds/a11wlk01.wav”); // Now define the granular synth ({var b = 10, trate, dur; trate = MouseY.kr(2,120,1); dur = 1.2 / trate; // if numChannels=2, similar to Pan2, -1 left, +1 right, // envbunum: -1, // the buffer number cont. 1. WHAT IS THE SPEED OF VARIATIONS? If you’re familiar with SuperCollider, you can load your own audio files and start manipulating them. [TGrains] //efficient granular synthesis on a buffer, from a single UGen, Also see various granular UGens by Josh Parmenter added for SC3.2: GrainSin, GrainFM, GrainBuf, GrainIn, Warp1, To read more on these techniques, Curtis Roads's Computer Music Tutorial is a good introduction, and his Microsound book explores many more possibilities.Â. If you count the unary and binary operators, there are over 300. In Granular Synthesis sounds are modelled out of microscopic particles of sound, short grains in the region of 10-100 milliseconds long. setable??

SuperCollider: Granulator & a GUI July 13, 2015 An example and working ground for a granular synthesis system in SuperCollider with GUI for a fullHD touch-screen surface. • Csound – comprehensive music software including granular synthesis (overview over granular synthesis opcodes) Because you can take tiny slices of sound, granular processing allows one to perform quite dramatic transformations on sound sources. Real-time systems became plausible in the 1980s. SuperCollider has over 250 unit generators.

In Granular Synthesis sounds are modelled out of microscopic particles of sound, short grains in the region of 10-100 milliseconds long. Luka Prinčič: a musician, sound & media artist, engineer and dj. //simple sine grain synthdef - note the all important doneAction, SynthDef(\sinegrain, {arg pan, freq, amp; var grain;Â. grain= SinOsc.ar(freq, 0, amp)*(XLine.kr(1.001,0.001,0.1,doneAction:2)-0.001); Synth(\sinegrain,[\freq,rrand(100,10000),\amp, exprand(0.05,0.1), \pan, 1.0.rand2]); //schedule 100 random grains over 1 secondÂ, Synth(\sinegrain,[\freq,rrand(100,10000),\amp, exprand(0.05,0.1), \pan, 1.0.rand2]); Â, Over time, we can change the characteristics of the swarm, for example, playing with its density, and control individual parameters of grains within tendency masks or following certain paths, //schedule 200 random grains over time, decreasing the range of allowed random frequencies and lowering the density over time, Synth(\sinegrain,[\freq,exprand(100,5000-(20*i)),\amp, exprand(0.05,0.1), \pan, 1.0.rand2]); Â, rrand((timeprop*0.1).max(0.01),timeprop*0.3).wait, //simple playbuf grain synthdef - note the all important doneAction, SynthDef(\sfgrain, {arg bufnum=0, pan=0.0, startPos=0.0, amp=0.1, dur=0.04;Â. grain= PlayBuf.ar(1,bufnum, BufRateScale.kr(bufnum), 1, BufFrames.ir(bufnum)*startPos, 0)*(EnvGen.kr(Env.perc(0.01,dur),doneAction:2)-0.001); Synth(\sfgrain,[\bufnum, b.bufnum, \startPos,rrand(0.0,1.0),\amp, exprand(0.005,0.1), \pan, 1.0.rand2]); Â, //schedule 200 random soundfile playback grains over time, with random offset positions into the soundfile and lowering the density over time, Synth(\sfgrain,[\bufnum, b.bufnum, \startPos,rrand(0.0,timeprop),\amp, exprand(0.005,0.1), \pan, 1.0.rand2]); Â, rrand((timeprop*0.1).max(0.01),timeprop*0.4).wait, Each grain might have many different parameters attached to it; some salient ones might be the pitch, the duration of the envelope, the pan position in the stereo field or the amplitude. Making music and art takes many hours of hard work and releasing it to the commons means less income from sales. Â. The sound can be made to disappear into a stream of tiny quanta and reappear, coalescing out of distinct particles: w=Window("My Window", Rect(100,500,200,200));Â, //A 200 by 200 window appears at screen co-ordinates (100, 500), slid=Slider(w,Rect(10,10,150,40)); //a basic slider objectÂ, slid.action_({lastval= slid.value;}); //this is the callback- the function is called whenever you move the slider, Synth(\sfgrain,[\bufnum, b.bufnum, \startPos,rrand(timestart,timeend),\amp, exprand(0.005,0.1), \pan, lastval.rand2, \dur, 0.1+(lastval*0.5)]); Â.

My sound goes from broken bass to noise, drone and sonic experiments. Greap also uses the concept of presets, which you can design in advance of a performance in order to create a kind of musical structure. (The example is based on code in the TGrains helpfile.)

Greap uses granular synthesis implemented in SuperCollider – tweaking audio files (samples) stored locally in the hard disk of your computer. There’s some things not yet working here (loading files from GUI for example), but it’s a milestone for one. The overall cloud can also have some sort of distribution for these parameters, which might lead to a tendency mask determining the range of frequencies of the particles allowed at differnet points in time, or control of the evolving density of the cloud.Â, The composer's work is to both specify the grains, and also control how they are used over time to make an interesting compositional structure.Â, These techniques were first conceptualised and explored in instrumental and electronic music by Iannis Xenakis (late 50s), and further investigated in computer implementation, notably by Curtis Roads and Barry Truax, from the early 1970s on. ... Granular Synthesis. // pitch !! We can control the swarms by scheduling grains over time, forming clouds of events.
