Select a random segment from a list of sequenced clips inside composition.

[Jorge Devandas]

For example, let’s say I have a bouncing ball animation loop, it lasts 1 second.
I would like the animation to have a different random sound at the start of each 1 second cycle.

I have a precomposition with 10 sequenced audio layers, each one of these sound clips with a duration of 1 second.

Would it be possible to apply an expression to the time remapping of the Sounds Precomp so that it randomly chooses one of these 10 segments, plays it for a second and then plays another one?

(I would guess it doesn’t require to identify each of the sound clips but the start/end of them since they all have the same duration, e.g. choose a random range from ‘0 to 1 sec’, ‘2 to 3’, etc.)

Let me know if I need to be more specific, thanks in advance!

Something like this maybe:

dur = 1;
numSegs = 10;
seedRandom(Math.floor(time/dur),true);
segIdx = Math.floor(random(numSegs));
t = time%dur;
segIdx*dur + t

Yes, that’s exactly what I was looking for. Thank you so much Dan!
