ABSTRACT:
A receiver and method is for receiving wireless transmissions including program data and locating data, and for determining its location from the locating data, and optionally from a stored representation of a venue and/or sound reproducing transducers therein. The receiver and method may also determine the actual speed of sound from current local atmospheric data, and determine a delay time to its location therefrom for delaying the received program data to be substantially in time alignment with natural sound, and to be so reproduced and/or recorded. A binaural microphone may pick up ambient sound which is mixed or combined with the delayed program data for producing a combined stereo audio signal.
