Abstract:
1. Apparatus, comprising: first stereophonic audio sensors located at a first sensor location in an arena to receive ambient sounds during an interval and produce a first stereophonic stream; second stereophonic audio sensors located at a second sensor location in the arena to receive ambient sounds during the interval and produce a second stereophonic stream; a virtual listening location selected in the arena at a first distance from the first stereophonic audio sensors and a second distance from the second stereophonic audio sensors; calculating a numerical value representative of signal power fading between the audio sensor locations and a selected location; a server coupled to the first and second sensors, for adding to signal values of the first and second stereophonic streams, a compensating signal based on the numerical value for the first and second distances to the virtual listening location, to produce an audio stream representative of audio that a listener would hear during the interval if-located at the virtual listening location in the arena; said server outputting said audio stream and additional audio streams as a plurality of audio streams representative of audio that a listener would hear during the interval if the listener was respectively located at any one of a corresponding plurality of virtual listening locations in the arena; and a transmitter for broadcasting the plurality of audio streams accompanied by a video stream depicting a scene of the arena during the interval; said plurality of audio streams capable of being individually recognized at television receivers receiving the broadcast and displayed with respective selection icons enabling a listener to play respective ones of the plurality of audio streams to hear audio that the listener would hear during the interval if the listener was respectively located at any one of the corresponding plurality virtual listening locations in the arena.
