there's a technique used in theaters,
where a short delay between left & right makes the sound appear to
come from the center.

and one that can focus the sound on a small area, so only one or a few people hear it.

the eardrum technique is new to me and i really want to try and build one.

the world is sound!

they've invented tons of cool new stuff.
there's a [product] shop here.
will check it out ( the ear is the judge - joe pass).
thanks.
