Hasher

Scrambled value with a hash function.
Inherits from: UGen : AbstractFunction : Object

Description

Returns a unique output value from -1 to +1 for each input value according to a hash function. The same input value will always produce the same output value. The input need not be in the range -1 to +1.

Class Methods

*ar (in: 0, mul: 1, add: 0)

*kr (in: 0, mul: 1, add: 0)

Arguments:

in

The input signal.

mul

Output will be multiplied by this value.

add

This value will be added to the output.

Examples

{ Hasher.ar(Line.ar(0,1,1), 0.2) }.play;

// Even adding a small amount to the input can result in a very different output. Compare these two examples:
(
{
    SinOsc.ar(
        Hasher.kr(MouseX.kr(0,10).round(1), 300, 500)
    ) * 0.1
}.play;
)

(
{
    SinOsc.ar(
        Hasher.kr(MouseX.kr(0,10).round(1) + 0.0001, 300, 500)
    ) * 0.1
}.play;
)

// Output stays constant while not moving the mouse.
(
{
    SinOsc.ar(
        Hasher.kr(MouseX.kr(0,10), 300, 500)
    ) * 0.1
}.play;
)
