XCut

Select one from an array of inputs. When index is changed, fades between the old and new signals using switch-and-ramp technique, minimizing audible artefacts/clicks.

Class methods

*ar(inArray, which, envLength, mul, add)

inArray - array of inputs.

which -  index of the signal to select.

envLength -  length of the x-fading window in samples, (default 2000).

Examples

// execute this line first

b=Buffer.read(s,"sounds/a11wlk01.wav");

// now, execute this block and click the mouse button to switch between two signals

    b2 = PlayBuf.ar(numChannels:1,bufnum:b,startPos:b.numFrames/2,trigger:LFPulse.ar((1/b.duration)*2));

    XCut.ar([b1, b2], MouseButton.kr(0,1,0))
