'Audio zooming' could enhance TV coverage
Article Summary
Imagine if you were watching television coverage of a football game, where none of the cameras could zoom in. It would be pretty frustrating, just having to go from one wide shot to another, never being able to get a close look at any of the players. That’s pretty much how things are with audio, however. Unless someone has their own microphone, or is within line of sight of a parabolic mic, you’re not going to be hearing them very well. In the near future, however, that may not be the case. Norway’s Squarehead Technology has developed AudioScope, a system that allows users to acoustically “zoom in” on individual people in a large area, and follow them as they move around.
