so I have 1/44100 = 22.6us to generate each sample. I can write it in
assembler, or C, but I only have 1k of program memory so assembler is
probably the way to go here. Where should I start? Is it possible to
make a -3db/octave digital filter in assembler which takes random 8 bit
numbers and spits out pink noise?
You could take this and modify it
