Logic Pro 10.7.5: 3D audio source below ear level

[emanuelleuname]

Hello everyone, I would like to augment the sound of footsteps in 3D. Front/back and left/right work, but I fail to make it sound like a source is coming from below. Can you recommend any plug-in or effect that could help to create this feeling in addition to spatial audio?

Any hint would be very much appreciated!

Humans do not have good sensors for vertical hearing. It's already bad at the top and we can hardly localize sounds from the bottom. Vertical localization takes place on the outer ear and many animals can move their ears for this. Mounting a loudspeaker underneath you can help, but you'd still have to tilt your head sideways to be sure where the sound is coming from.

Our forum colleague Christian Luther (@hugoderwolf) explains the basics in two articles in English:
Sound Localization Basics
Sound Localization In The Median Plane
In the second article, look at the diagram of Blauert's bands. They don't even show a curve for hearing from below. I assume that Mr. Blauert's probands could not sufficiently localize sounds from this direction.

So the answer to your question is:
You can't process your sound so that every listener registers it as coming from below. Not all of us sit inside a spherical array of speakers ;-)

Because vertical localisation occurs, if at all, on the outer ear, you are worse off with your headphones than with loudspeakers.
