A microphone that selects the speaker

Human beings are wonderful creatures. They can have a conversation in busy streets and other noisy areas. We select what we want to listen to.

But a microphone? Believe me, I have a tough time recording interviews in such situations. I spend effort in selecting the microphone. Should I use a gun mike, a collar mike, ....?

And at the end of the exercise I have to spend time cleaning up the audio track and ultimatly end up with a bad sound track.

A recent paper in PNAS (August 25, 2015 | vol. 112 | no. 34 | 10595–10598) gives me hope that, one day, I will carry a microphone that is as selective as I am.

The cocktail-party-listener prototype was fabricated with a metamaterial - acrylonitrile butadiene styrene plastics using fused filament fabrication 3D printing technology.

Guys, are you listening or what?
