Audio source triangulation #19

Open Martin2kid opened 4 years ago

Martin2kid commented 4 years ago

This is just future suggestion to already impressive work,

What if rpi-deep-pantilt can also triangulate audio source, point to that direction.

Perhaps 2 microphone practically spaced far enough apart & measure 2 audio channel input speed difference, triangulate & apply toward servo angle processing and point to that direction? (I know it'll perhaps require 360 degree servo)

Hey, just wanted to give you an update on this issue.

I'm experimenting with a 5/8 radial mic array now. Will keep you posted if I publish my directional models. I think the scope of those models is a bit beyond this project, so I'd release in a separate codebase.
