GEOps

Companion object GEOps

final class GEOps extends AnyVal

GEOps are operations for graph elements (GE). Instead of having these operations directly defined in each UGen, which is a huge list, they appear here as extension methods. Therefore, you can write SinOsc.ar.linLin ... as if linLin was defined for GE or SinOsc.

Many of these operations are defined for constant numbers, as well, for example you can write 0.5.linLin .... These operations are defined separately.

def sCurve: GE
Scans a sinusoidal S-shaped function ("easy in, easy out") rising from zero to one across the input signals' range of 0 and 1.
Scans a sinusoidal S-shaped function ("easy in, easy out") rising from zero to one across the input signals' range of 0 and 1. The function begins to rise from the zero at the interval start to 0.5 at the center to 1.0 at the interval end. When the input is smaller than zero, the output is zero, and when the input is larger than one, the output is one.
def scaleNeg(b: GE): GE
Scales the negative part of the input by the argument, outputs positive input unaltered.
Scales the negative part of the input by the argument, outputs positive input unaltered. Thus equivalent to a.min(0) * b + a.max(0).
Example
```
play {
  // increasing half-wave asymmetry
  (SinOsc.ar(500) * 0.25).scaleNeg(Line.ar(1, -1, 4))
}
```
def sig_!=(b: GE): GE
Compares two signals and outputs one if they are different, otherwise zero.
Compares two signals and outputs one if they are different, otherwise zero.
Note that this can be surprising if the signals are not integer, because due to floating point noise two signals may be "almost identical" but not quite, thus resulting in an output of one.
def sig_==(b: GE): GE
Compares two signals and outputs one if they are identical, otherwise zero.
Compares two signals and outputs one if they are identical, otherwise zero.
Note that this can be surprising if the signals are not integer, because due to floating point noise two signals may be "almost identical" but not quite, thus resulting in an output of zero.
def signum: GE
Takes the signum of the signal, being 1 for positive signals, -1 for negative signals, and zero for a zero input.
Takes the signum of the signal, being 1 for positive signals, -1 for negative signals, and zero for a zero input.

}
```
def sqrt: GE
Takes the square root of the signal.
Takes the square root of the signal. If the input is negative, it returns the negative of the square root of the absolute value, i.e. sqrt(-2) == -sqrt(2), so the output is valid for any input.

def squared: GE

def sum3Rand: GE
Produces a random signal following an approximated Gaussian distribution between zero and the input signal.
Produces a random signal following an approximated Gaussian distribution between zero and the input signal. It follows the formula Mix.fill(3)(Rand(0.0, 1.0)) - 1.5 * (2.0/3), thus summing three evenly distributed signals
def sumSqr(b: GE): GE
Calculates the sum of the squared arguments, equivalent to the formula (a*a) + (b*b).
Calculates the sum of the squared arguments, equivalent to the formula (a*a) + (b*b).
Example
```
play {
  (SinOsc.ar(800) sumSqr SinOsc.ar(XLine.kr(200, 500, 5))) * 0.125

def tan: GE
Uses the input signal as argument to the tangent (trigonometric) function.
def tanh: GE
Uses the input signal as argument to the hyperbolic tangent (trigonometric) function.
def thresh(b: GE): GE
A threshold comparison where the output is zero when input signal is less than the argument, otherwise the input signal is passed.
A threshold comparison where the output is zero when input signal is less than the argument, otherwise the input signal is passed.

play {
  // a low-rent gate

def triWindow: GE
Scans the triangular window function between the input signal's range of 0 and 1.
Scans the triangular window function between the input signal's range of 0 and 1. The triangular window moves from linearly from the zero at the interval start to 1.0 at the center (input 0.5) back to 0.0 at the interval end. Outside of the interval [0, 1], the output will be zero.
def trunc(b: GE): GE
Removes the fractional part of the input signal.
Removes the fractional part of the input signal.

def unary_!: GE
Logically negates the signal.
Logically negates the signal. Outputs 1 if the signal is greater than zero, otherwise outputs 0.

def unary_-: GE

Negatives the signal.

Negatives the signal. As if multiplying the signal by -1.

Example

// pseudo-stereo by phase inversion
play {
  val a = LFNoise1.ar(1500) * 0.5
  Seq(a, -a)

def unary_~: GE
Treats the signal as integer numbers and inverts its bits.
def welchWindow: GE
Scans the Welch window function between the input signal's range of 0 and 1.
Scans the Welch window function between the input signal's range of 0 and 1. The Welch window is a parabolic curve starting and ending at zero at the interval boundaries, and going to 1.0 at the center (input 0.5). Outside of the interval [0, 1], the output will be zero.
def wrap(low: GE, high: GE): GE
Wraps the input signal at the boundaries given by the arguments.
Wraps the input signal at the boundaries given by the arguments. If the input falls below low, it is wrapped back to high. If the input rises above high, it is wrapped back to low.

def wrap2(b: GE): GE
Wraps the input signal at the boundaries given by +/- the argument.
Wraps the input signal at the boundaries given by +/- the argument. If the input falls below -b, it is wrapped back to +b. If the input rises above +b, it is wrapped back to -b.
