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...
