Configurable three-dimensional sound system

摘要

A method and a system for simultaneously generating configurable three-dimensional (3D) sounds are provided. A 3D sound processing application (3DSPA) in operative communication with a microphone array system (MAS) is provided on a computing device. The MAS forms acoustic beam patterns and records sound tracks from the acoustic beam patterns. The 3DSPA generates a configurable sound field on a graphical user interface using recorded or pre-recorded sound tracks. The 3DSPA acquires user selections of configurable parameters associated with sound sources from the configurable sound field. The 3DSPA dynamically processes the sound tracks using the user selections to generate a configurable 3D binaural sound, surround sound, and/or stereo sound. The 3DSPA measures head related transfer functions (HRTFs) in communication with a simulator apparatus that simulates a human's upper body. The 3DSPA generates the binaural sound by processing the sound tracks with the HRTFs based on the user selections.

1. A method for simultaneously generating configurable three-dimensional sounds, comprising:
providing a three-dimensional sound processing application on a computing device, wherein said three-dimensional sound processing application is executable by at least one processor configured to simultaneously generate said configurable three-dimensional sounds; providing a microphone array system embedded in said computing device, said microphone array system in operative communication with said three-dimensional sound processing application in said computing device, wherein said microphone array system comprises an array of microphone elements positioned in a three-dimensional space, wherein said microphone array system is configured to form a plurality of acoustic beam patterns, wherein each of said plurality of said acoustic beam patterns point to a different direction in said three-dimensional space, and wherein said each of said plurality of said acoustic beam patterns point to different positions of a plurality of sound sources in said three-dimensional space; recording sound tracks from said acoustic beam patterns by said microphone array system, wherein each of said recorded sound tracks corresponds to one of said directions in said three-dimensional space; generating a configurable sound field on a graphical user interface provided by said three-dimensional sound processing application using said recorded sound tracks, wherein said configurable sound field comprises a graphical simulation of said sound sources in said three-dimensional space on said graphical user interface, and wherein said configurable sound field is configured to allow a configuration of positions and movements of said sound sources; acquiring user selections of one or more of a plurality of configurable parameters associated with said sound sources from said generated configurable sound field by said three-dimensional sound processing application via said graphical user interface; and dynamically processing said recorded sound tracks using said acquired user selections by said three-dimensional sound processing application to generate one or more of a configurable three-dimensional binaural sound, a configurable three-dimensional surround sound, and a configurable three-dimensional stereo sound.
