Targeted audio in multi-dimensional space
First Claim
1. A computer-implemented method for providing sound from multiple audio sources, the method comprising:
- playing a first audio stream from a first source through a multi-speaker audio system;
receiving a signal indicating a need to play a second audio stream from a second source through the multi-speaker audio system;
determining adjustments to be made to the first audio stream to move an acoustic image of the first audio stream in multi-dimensional space from a first location to a second location, wherein an acoustic image is an apparent location of a source of an audio stream; and
applying adjustments to a signal of the first audio stream in order to move the acoustic image of the first audio stream from the first location to the second location; and
playing the second audio stream so that an acoustic image of the second audio stream is located in a third location that is different from the second location, and simultaneously playing the first audio stream in the second location.

Abstract
In general, the subject matter described in this specification can be embodied in methods, system, and program products for providing sound from multiple audio sources. A first audio stream is played from a first source through a multi-speaker audio system. A signal indicating a need to play a second audio stream is received from a second source. Adjustments to be made to the first audio stream to move an acoustic image of the first audio stream in multi-dimensional space from a first location to a second location are determined. Adjustments are applied to a signal of the first audio stream in order to move the acoustic image of the first audio stream from the first location to the second location. The second audio stream is played so that an acoustic image of the second audio stream is located in a third location. The first audio stream is simultaneously played.

12. A system for providing positional sound from multiple audio sources, the system comprising:
-
a multi-channel electronic amplifier arranged to produce signals for producing audible sound on multiple independent channels; a plurality of individually addressable speakers, with each speaker connected to one of the channels of the electronic amplifier; and an acoustic image generation unit programmed to modify a signal for a first audio stream upon identifying an arrival of a second audio stream, so as to provide one or more signals to the amplifier so that an acoustic image for the first audio stream is positioned at a location in multi-dimensional space that is separated from a location in multi-dimensional space for an acoustic image of the second audio stream when the first and second audio streams are reproduced simultaneously by the speakers, wherein an acoustic image is an apparent location of a source of an audio stream. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

20. A system for providing positional sound from multiple audio sources, the system comprising:
-
a multi-channel electronic amplifier arranged to produce signals for producing audible sound on multiple independent channels; a plurality of individually addressable speakers, with each speaker connected to one of the channels of the electronic amplifier; and means for modifying a signal for a first audio stream upon identifying an arrival of a second audio stream, so as to provide one or more signals to the amplifier so that an acoustic image for the first audio stream is positioned at a location in multi-dimensional space that is separated from a location in multi-dimensional space for an acoustic image of the second audio stream when the first and second audio streams are reproduced simultaneously by the speakers, wherein an acoustic image is an apparent location of a source of an audio stream.
