dsp.ColoredNoise pinknoise's max and min is not 1 even bounded output is true?

app.fileReader = dsp.ColoredNoise('pink',2048,1,OutputDataType='double', BoundedOutput=true)
Why does the ColoredNoise function work when using for white noise but not for pink?

As I understand it, you are expecting the values +1 and -1 as the minimum and maximum, respectively, for the "pink" "NoiseColor" parameter in the "ColoredNoise" function. The documentation mentions that, except for the "white" color, a color filter is applied to ensure that the generated noise never exceeds or equals +1 or -1. Specifically, for the "pink" value, the output distribution of the filtered noise is quasi-Gaussian, which is always bounded within (+1, -1). More information about "BoundedOutput" and other "ColoredNoise" parameters can be found at the following link:
