Maybe have a look at my pink noise generator here:https://github.com/Stenzel/newshadeofpinkIgnore the hack on floats and focus on the integer version. The core is...
A more efficient way to deal with PDM data is to group the 1-bit samples by eight into unsigned chars and do FIR filtering by using these as indices in lookup tables....
Instead of summing multiple independant noise sources, it is also possible to use an allpass filter to modify the distribution, call it a distribution filter. This...
It looks like your approach is wrong - you sum up FFT results for each 1/3 octave and expect the output to resemble 1/f scaling. However, the number of FFT bins...
