Examples

An instance implements the kr method and delivers [elevation, atzimuth, roll]a = ARHeadtracker.new; // look straight forward to calibrate the system a.reset; // create the virtual room p = ProxySpace.push; // simple test with sinus freq controled by azimuth ~test = { SinOsc.ar(200 + (a.kr[1] * 100), 0, 0.2) }; ~test.play; ~test.clear; // more complex example as headtracker in a virtual environment VirtualRoom.revTime = 1; VirtualRoom.revGain = 0.1; VirtualRoom.hfDamping = 1; VirtualRoom.init; VirtualRoom.start; { VirtualRoom.ar }.play; // position the listener in the middle of the room and assign the // head tracker data to the orientation of the listener ~listener = { | x=2.5, y=4, z=2.5, o=0| [x,y,z, a.kr[1]] }; v = VirtualRoom.new; v.listener = ~listener; v.room = [0, 0, 0, 5, 8, 5]; v.refGain = 1; v.play; // adding a source to the scene (slightly right off) ~noisy = { EnvGen.kr(Env.adsr, Impulse.kr(3)) * PinkNoise.ar(1) }; ~noisyPos = { | x=3.5, y=3, z=2.5 | [x,y,z] }; v.addSource( ~noisy, "test1", ~noisyPos); v.removeSource("test1"); // play and stop the virtual room v.play; v.stop; // stop the rendering engine VirtualRoom.stop; p.pop;
