It’s probably an offending codec, and compressed audio. Try to convert it to a different codec and uncompress audio using Quicktime Pro.

Hi there,

I wrote this a few months ago.
It’s based on the 2D noise-function, and uses the logic that if you follow a circle through a “noise field”, you end up at the same value.
You have to call the function and it just returns a number, so you still have to add that number to the current value.
For 2 or 3 dimensional properties (position for example), you have to call it multiple times with different seeds:


// for a 1-dimensional property: (loopTime is in seconds)
value+loopedWiggle (freq=1,amp=50, oct=2, amp_mult= .5, t=time, loopTime=3, seed=200);

function loopedWiggle (freq, amp, oct, amp_mult, t, loopTime, seed) {
seedRandom(seed, timeless = true);
startPos=random([5000,5000]);

radius=(loopTime/Math.PI)*freq;
// if the looptime is long, the radius should increase, otherwise the frequency would drop. 8-P

maxValue=0;
n=0;
multiplier=1;
for (i=1; i<=oct; i++) { radius=radius*(i-0.5); x=startPos[0] + Math.cos(degreesToRadians(360*t/loopTime + oct))*radius; y=startPos[1] + Math.sin(degreesToRadians(360*t/loopTime + oct))*radius; n += noise([x,y])*multiplier; maxValue += multiplier; multiplier *= amp_mult; } return n*amp; }

for position (2d) you would start out with something like this:


wiggledx=loopedWiggle (freq=1,amp=50, oct=2, amp_mult= .5, t=time, loopTime=3, seed=200);
wiggledy=loopedWiggle (freq=1,amp=50, oct=2, amp_mult= .5, t=time, loopTime=3, seed=600);

value+[wiggledx,wiggledy]

Hey Rook,

here’s it’s ‘sister-script’ it does the same thing with vertical masks:

Oh,

and don’t copy-paste it from your e-mail,
go to the website and you’ll see that it looks different: I put some HTML tags in there (all the >code< -stuff )
to layout it a bit, but in the e-mail they show up in the text, and they’re not supposed to be in the expression

that’s prob. what went wrong.
