Abstract: An acoustic customization system to enhance a user's audio environment. One type of enhancement would allow a user to wear headphones and specify what ambient audio and source audio will be transmitted to the headphones. Added enhancements may include the display of an image representing the location of one or more audio sources referenced to a user, an audio source, or other location and/or the ability to select one or more of the sources and to record audio in the direction of the selected source(s). The system may take advantage of an ability to identify the location of an acoustic source or a directionally discriminating acoustic sensor, track an acoustic source, isolate acoustic signals based on location, source and/or nature of the acoustic signal, and identify an acoustic source. In addition, ultrasound may be serve as an acoustic source and communication medium.

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.

Abstract: An audio source location, tracking and isolation system, particularly suited for use with person-mounted microphone arrays. The system increases capabilities by reducing resources required for certain functions so those resources can be utilized for result enhancing processes. A wide area scan may be utilized to identify the general vicinity of an audio source and a narrow scan to locate pinpoint positions may be initiated in the general vicinity identified by the wide area scan. Subsequent locations may be anticipated by compensating for motion of the sensor array and anticipated changes in source location by trajectory. Identification may use two or more sets of characterizations and rules. The characterizations may use computationally less intense analyses to characterize audio and only perform computationally higher intensity analysis if needed. Rule sets may be used to eliminate the need to track audio sources that emit audio to be eliminated from an audio output.

The system may specify aspects of audio to be modified by specification of filtering algorithm, characterization of audio samples, monitored distortion, user selection, location specification or environmental specification and may be used in a social networking system.
