Vertical Positioning Effect ...

[pethenis]

Unless you're mixing in Dolby Atmos I doubt there's anything for it ;-)

If you ae making all the sounds yourself, I would come up with sounds that have a certain pitch. All sounds also have a musical pitch like C or whatever.

Now just make sure the highest object also has the highest pitch. Listen to the backgroundmusic and try to layer a fitting chord on top of that.

Might be fun!

if you are using Apple's Logic Pro then you might take advantage of the Binaural mixer provided with the app. But anything you do would be only applicable while monitoring/ listening through headphones. As Pethenis (that's greek for dying, right?) said Dolby atmos would be the only medium to provide 3D sound placement with a speaker system.

Certain frequency bands are associated with vertical positioning.
Grab a copy of Blauert's standard-book on spatial hearing, there is a chart laying these out somewhere in there.

IIRC frequency content above 8kHz is associated with elevated sound sources, as you can see here (image D):

I think Wave Arts claim to do something similar to what you're looking for:
Wave Arts | Plugins | Panorama

The ear/brain is not all that good at height differential.

I would try the same sound but pitch them apart -- by how much depends. Then I would hi-pass one and lo-pass the other, but by a significant amount. Meaning, don't hi-pass at 1k and lo-pass at 1k. I would "leave a hole" in between.

+1 I have used this with decent results, works best when used in a stereo field.
