First Claim
Patent Images
1. An audio spatialization system comprising:
- a personal speaker system;
an audio spatialization engine having an output connected to said personal speaker system;
a directionally discriminating acoustic sensor having an audio output connected to said audio spatialization engine;
a first motion sensor associated with said personal speaker system;
a second motion sensor associated with said directionally discriminating acoustic sensor; and
a listener position orientation unit having a first input connected to said first motion sensor, a second input connected to said second motion sensor, and an output connected to said audio spatialization engine representing the position and orientation of an audio source direction detected by said directionally discriminating acoustic sensor relative to an orientation of said personal speaker system;
wherein said audio spatialization engine adds spatial characteristics to said audio output of said directionally discriminating acoustic sensor audio source on the basis of said output of said listener position/orientation unit.

Abstract
An audio customization system operates to enhance a user'"'"'s audio environment. A user may wear headphones and specify what portion the ambient audio and/or source audio will be transmitted to the headphones or the personal speaker system. The audio signal may be enhanced by application of a spatialized transformation using a spatialization engine such as head-related transfer functions so that at least a portion of the audio presented to the personal speaker system will appear to originate from a particular direction. The direction may be modified in response to movement of the personal speaker system.
