LinCongN

A non-interpolating sound generator based on the difference equation:

x[n+1] = (a * x[n] + c) % m

The output signal is automatically scaled to a range of [-1, 1].

===Examples===

// default initial parameters
play { LinCongN.ar(MouseX.kr(20, SampleRate.ir)) * 0.2 }

// randomly modulate parameters
play {
 LinCongN.ar(
   LFNoise2.kr(1.0).mulAdd(1e4, 1e4),
   LFNoise2.kr(0.1).mulAdd(0.5, 1.4),
   LFNoise2.kr(0.1).mulAdd(0.1, 0.1),
   LFNoise2.kr(0.1)
 ) * 0.2
}

// as frequency control
play {
 SinOsc.ar(
   LinCongN.ar(
     40,
     LFNoise2.kr(0.1).mulAdd(0.1, 1),
     LFNoise2.kr(0.1).mulAdd(0.1, 0.1),
     LFNoise2.kr(0.1)
   ).mulAdd(500, 600)
 ) * 0.4
}
