class:: Hasher
summary:: Scrambled value with a hash function.
categories::  UGens>Filters>Nonlinear, UGens>Random

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.

classmethods::

method::ar, kr

argument::in
The input signal.

argument::mul
Output will be multiplied by this value.

argument::add
This value will be added to the output.

Examples::

code::
{ 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;
)
