Abstract
A method for localization of sound in a speaker system comprises determining speaker locations of a plurality of speakers in a speaker system, determining a user location of a user within a room, and modifying audio signals to be transmitted to each of the plurality of speakers based on the user location in the room relative to a corresponding one of the speaker locations. An optimum modification of the audio signals for each of the plurality of speakers includes eliminating locational effects of the user location within the room.
Claims24
A method for localization of sound in a speaker system, the method comprising:
- a) determining speaker locations of a plurality of speakers in a speaker system wherein determining speaker locations comprises:
- using at least two microphones to determine a distance between the at least two microphones and each of the plurality of speakers;
- using Independent Component Analysis to determine original signals from a mixture of sounds received at the at least two microphones and calculating a location of each original signal relative to the at least two microphones;
- and
- correlating the calculated location of each original signal to a known speaker channel configuration;
- b) determining a user location of a user within a room;
- and
- c) modifying audio signals to be transmitted by each of the plurality of speakers based on the user location in the room relative to a corresponding one of the speaker locations, wherein modifying the audio signals to be transmitted by each of the plurality of speakers includes eliminating locational effects of the user location within the room.

A non-transitory computer-readable medium with instructions embedded thereon, wherein the instructions when executed cause a processor to carry out a method for localization of sound in a speaker system, comprising:
- a) determining speaker locations of a plurality of speakers in a speaker system wherein determining speaker locations comprises:
- using at least two microphones to determine a distance between the at least two microphones and each of the plurality of speakers;
- using Independent Component Analysis to determine original signals from a mixture of sounds received at the at least two microphones and calculating a location of each original signal relative to the at least two microphones;
- and
- correlating the calculated location of each original signal to a known speaker channel configuration;
- b) determining a user location of a user within a room;
- and
- c) modifying audio signals to be transmitted by each of the plurality of speakers based on the user location in the room relative to a corresponding one of the speaker locations, wherein modifying the audio signals to be transmitted by each of the plurality of speakers includes eliminating locational effects of the user location within the room
