# Noise Sine Wave Node
|
|
|
|
## Description
|
|
|
|
Returns the sine of the value of input **In**. For variance, psuedo-random noise is added to the amplitude of the sine wave, within a range determined by input **Min Max**.

## Generated Code Example
|
|
|
|
```
|
|
void Unity_NoiseSineWave_float4(float4 In, float2 MinMax, out float4 Out)
|
|
{
|
|
float sinIn = sin(In);
|
|
float sinInOffset = sin(In + 1.0);
|
|
float randomno = frac(sin((sinIn - sinInOffset) * (12.9898 + 78.233))*43758.5453);
|
|
float noise = lerp(MinMax.x, MinMax.y, randomno);
|
|
Out = sinIn + noise;
|
|
}
|
