Fantastic

amazing, many thanks,
I noticed it is still emitting at areas where audio waves are zero though

Hello legendary noseman, I think the best expression of what I want to achieve will be "how to control the speed of the particles using audio form that affect the spline deformation in Y ", it is 100 at a certain peak and zero at the horizontal status

Hello
I have a spline that has an audio effector that drives the Y movement of the point. The Spline revisualises the audio wave forms.
I want to emit particles from the peak areas of the Spline (peak points of the audio wave), in a fashion where there is no emission is 0% where the spline points doesn't move at all , and 100% when it is in a defined peak area. The result will help to build a sort of sound ghost made of particles.
I hope it is not vague. I am joining the file and a reference image to show what I mean
Many thanks

I think I found the answers for both questions
if it stalls again, I will start a new thread
All the best

Thanks Prof
My bad for the thread, I didn't want to flood with many threads, will keep in my mind
two questions:
how we can make the birth behaves the same, instead of just popping out, I want to animate the radius progressively until it reaches the radius value
how to tell mograph to copy the radius to the scale of the clones ? I saw you created one but in the scene it stays constant
Best

I forgot to add that also the appearance of the particles should be progressive, let's say birth / death around 3-4 frames progression before reaching the radius

Hello
I know it is a simple question, but how we can map the radius of the particles so it is getting smaller before the end of its life, I found the "Radius Over Age" scene in the Asset browser but cannot apply it to my emitter scene

Hello
When a viewport that contains an animated video is deselected "camera view", scrubbing time in another viewport don't update the video frames in the camera view, the viewport that contains the camera view to the animated sequence must be selected.
Is there a way to lock the viewport that contains the video file so working on different viewport can let the video in the locked frame refreshing
