Is there a node.js module that can generate 1/f (pink noise) fluctuations?


I'm looking for a node.js module that would be able to generate fluctuations (of any sort) that would follow the S(f) = 1/f "pink / fractal noise" pattern. That means, that if we performed Fourier analysis of the time-series we'd find that there's a few high-amplitude fluctuations and many low-amplitude ones with the following distribution of signal:

If you don't know about the module, then maybe know some mathematical node.js toolkit that could help me generate this?

Thank you!
