Absolutely. Also don't forget about [swap] if you also eventually need to change the dividend, and/or the numbers arrive out of order. | / [swap 50] | / [/ ] On Sun, Nov 15, 2015 at 3:58 AM, Roman Haefeli wrote: > [expr 50/$f1] can also be expressed as > > [50

There's [rojo~] in mrpeach, if by brown noise you mean red noise. (brownian noise?) [rojo~] tends to grow out of bounds, which is a problem with correlated noise: if you want long term correlations you have to be ready for the noise to get very loud. So in practice there is no red noise possible,

Here's a simple way to do reddish noise: low-pass filtered white noise. By making the low-pass cutoff infrasonic it sounds like red or brown noise. The gain needs to be adjusted as the cutoff changes.. Martin On Fri, Nov 13, 2015 at 10:35 PM, Alexandre Torres Porres wrote: >

hi, wondering how to implement brown noise in Pd (vanilla or extended) - moreover, I'd like and if there's an external that does it. same about grey noise thanks alex ___ Pd-list@lists.iem.at mailing list UNSUBSCRIBE and account-management ->

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
