Thank you very much for your help on my problem. Luckily in the end, my client just decided to go for a more accurate visualization so I ended up using audio beam which is much simpler. I’ve attached a frame of what I ended up.

I haven’t solved the problem of using particular, I would actually think that since the particle has been already emitted, changing the amp or frequency parameter should only change future particles so I didn’t expect the weird behavior I got.

In any case, that’s a bridge I shall cross if I have to do something similar in the future. Thanks very much for your time and help on this, it’s much appreciated!

Hi,

I’m having a problem keying the parameters with this code. Animating the freq, amp or soft variables gives me really jerky and weird animation, where the entire graph will suddenly expand or jump. Is there something I’m doing wrong please?

Thanks very much!

Thanks very much for your reply!

I actually need to fill the area under the line created by the stepped graph rather than creating the solids on their own.

Using aux particles I get this effect:

Because they are emitted in order there’s a sloping / cascading effect.

Can I check with the code you’ve kindly provided for the line, is there a way to stop any movement in the x axis when the line is travelling in the y axis? So that I end up with straight vertical lines between each bar graph?

hope I’m making sense,thanks ever so much for your help!

Thanks so much! That works beautifully.

If I may just bother you with a further question please. In this reference:

On the right side of the image, there are graduated bars that descend from the peak of the graph. I tried achieving that by emitting auxiliary particles but of course they’re emitted in turn and so they don’t fall as a uniform bar but more like a continuous cascade.

I’m guessing that I need to be able to read when the Y value hits a peak / plateau, and then tell another emitter to emit a block right at that point. Does that sound right to you?

Thanks so much for your help!

Oh wow! Thanks very much! I now have a stepped graph that’s fantastic!

The steps are all different widths at the moment, is there a way to make them all the same width as in the reference?

Thanks very much, I really appreciate your help!

Thanks for your reply. No there’s no significance, I was just after an interesting way waveform and decided to use that to represent frequency. Is it possible to do it with expressions? Many thanks.

Sorry this is the image I’m trying to reference:

Thanks for your reply, but I still can’t figure it out.

I’ve already linked the position of the emitter to a null moving along the right path. Now, I want to offset that expression with the animation of another null. How do I create this parenting with just expressions?

Many thanks!
