Picking a Single Voice out of a Crowd
Interesting new technology.
Squarehead’s new system is like bullet-time for sound. 325 microphones sit in a carbon-fiber disk above the stadium, and a wide-angle camera looks down on the scene from the center of this disk. All the operator has to do is pinpoint a spot on the court or field using the screen, and the Audioscope works out how far that spot is from each of the mics, corrects for delay and then synchronizes the audio from all 315 of them. The result is a microphone that can pick out the pop of a bubblegum bubble in the middle of a basketball game….
Audio from all microphones is stored in separate channels, so you can even go back and listen in on any sounds later. Want to hear the whispered insult that caused one player to lose it and attack the other? You got it.
