Slope slope of signal

Slope.ar(in, mul, add)

Measures the rate of change per second of a signal.

Formula implemented is:

out[i] = (in[i] - in[i-1]) * sampling_rate

in - input signal to measure.

(

{

var a, b, c, scale;

a = LFNoise2.ar(2000); // quadratic noise

b = Slope.ar(a); // first derivative produces line segments

c = Slope.ar(b); // second derivative produces constant segments

scale = 0.0002; // needed to scale back to +/- 1.0

[a, b * scale, c * scale.squared]

}.plot

)
