Hi,

i have some questions on how the 3D reverberations interact with the geometries.

First, does the dimension of the geometry have an impact on the reverberation effect ?

I mean, for example, if i create two cubes, a little one and a big one, and i define a reverb (3D sphere) around
those two cubes (the two spheres have the same dimension and the same reverb preset), should i hear a
difference of reverb due to the difference of geometry ??

I would also like to have your opinion on how to manage the reverberation for a tunnel. This tunnel can be curved,
or placed on a sloped ground.
Should i create an unique 3D reverb on this object, or should i create several reverbs ? In the last case, have you
some ideas to determine the center and the dimension of each sphere ?

Thanks, (and sorry for my english)

hugo.

The reverb effect is defined by reverb parameters, the geometry will not make a reverb sound different. However, the geometry [i:38hcupqq]can [/i:38hcupqq]be used to enclose a reverb effect.

No, the geometry will not affect the sound of the reverb. What you can do with your two cubes example is make two different reverb presets and then set the reverb occlusion of the each cube to 1.0. This will mean that the reverb will not be heard outside of the cubes and each cube will have a different sounding reverb effect inside it.

It should be sufficient to make a reverb sphere big enough to cover the entire tunnel and set the walls of the tunnel to have 1.0 reverb occlusion. The reverb will not be occluded at the ends of the tunnel so you might need to put a wall either end to properly enclose the reverb. If the tunnel is so curved that it blocks line of sight to the centre of the reverb sphere then you would probably need to use multiple spheres.
