Method for adjusting audio for listener location and head orientation within a physical or virtual space

Abstract

The present invention is a system that detects the location and head orientation of a live performer on stage in front of an audience and adjusts the individual elements of the mix either by changing them at the listener's position or by feeding the location and orientation information back to the monitor mixer or a combination of both. The adjustments would include left/right panning, relative levels, equalization, transient response, reverberation levels, panning, and time delay, as well as other possible modifications to the signal so that the performer senses that he/she is actually listening to the various instruments, vocals, acoustic space and audience, in their real or virtual locations.

         3 . A method of detecting, for at least one live performer who is moving, the location of the performer moving and adjusting the sound mix sent to the moving performer's in ear monitor (IEM) based on the performer's location comprising the steps of:
 providing a location identification tag for each performer moving so as to locate the performer as the performer moves;   providing a microphone to send a signal from the performer to a monitor mixer;   each mixer configured to detect changes in the signal sent to the monitor mixer dependent on the location of each performer; and   providing a computer in communication with the monitor mixer, the computer configured to detect the location of each performer, and the computer configured to vary the output from the monitor mixer to the in ear monitor (IEM) of the performer wearing the location identification tag dependent on the performer's location.   
     
     
         4 . A method of detecting, for at least one live performer who is moving, the location of the performer moving and the orientation of the moving performer's head, and adjusting the sound mix sent to the moving performer's in ear monitor (IEM) based on the performer's location and head orientation, comprising the steps of:
 providing a location identification tag for each performer moving so as to locate the performer and in ear monitors (IEM) that are capable of transmitting a signal showing the orientation of the performer's head as the performer moves;   providing a microphone to send a signal from the performers to a monitor mixer;   configuring each mixer to detect changes in the signal sent to the monitor mixer dependent on the location of each performer and the orientation of the performer's head; and   providing a computer in communication with the monitor mixer, the computer configured to detect the location and orientation of the head of each performer, and the computer to vary the output from the monitor mixer to the in ear monitor (IEM) of the performer, dependent on the performer's location and the orientation of the performer's head.
