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;
)
