You can get an approximate brown noise by running a noise source through
[fexpr~ if(abs($x+$y)>1.0,$y-$x,$x+$y)] (an integrator with +/- 1 bounds.
Scale your noise source by somewhere in the 0.05 to 0.001 range (I don't
know the exact value). If you want a quasi-gaussian noise source, you can
just add 6 to 12 or so independent [noise~]s together.
I'm sure there are more precise ways, but if you need something quickly....
