# How to measure the “correctness” of a pink noise generator?

I've implemented a pink noise generator for audio applications. How can I measure how close of an ideal pink noise is my output?

I do not have access to Matlab or Mathematica. I would prefer a solution involving open-source software such as GNU Octave or SciPy.

scipy.signal contains ample FIR filter design methods suitable for designing filters.
