Two Norwegian physicists have developed a technology that enables recording (and hearing) one voice in a noisy indoor crowd. This remarkable invention uses 315 microphones embedded in a circular overhead dish, a wide-angle camera and (of course) computers. How does it work its’ magic? Physicist-inventor Morgan Kjolerbakken told the New Scientist, “if we correct the audio arriving at three microphones, then we have a signal that is three times as strong.” Check out this video of AudioScope in action:
Who’s Zooming Who?
Kjolerbakken and his collaborator Vibeke Jahr have patented AudioScope and founded a new company: Squarehead Technology. Promoting the new system, the company’s website asks,
“Have you ever missed a sound effect and wished that you had recorded it for replay editing? This is no longer a problem. Digital audio from 315 separate microphones is stored in synchronization with the images. The operator can go back and zoom in on interesting areas and select replays with amplified sound.”
This is a mind-blowing advance in audio. Besides capturing the curses and comments of athletes and coaches, how can you imagine this technology being used to enhance and deepen coverage at mega-events? Have any ideas? Please share in comments below.
