    摘要： A specification of a mesh of filters may be defined on a grid in a three-dimensional space presented in a user interface. A plurality of sound tracks may be determined, wherein each of the sound tracks is associated with a corresponding sound source that may be represented in the three-dimensional space along with a listener. Responsive to user configuration of a position of the listener and/or positions of the sound sources in the three-dimensional space, a plurality of filters may be selected based on the mesh of filters and the positions of the sound sources and the listener in the three-dimensional space. Each of the filters may be applied to a corresponding one of the plurality of sound tracks to generate a plurality of filtered sound tracks and the three-dimensional sound may be generated based on the plurality of filtered sound tracks.

    摘要： A method and system for enhancing a target sound signal from multiple sound signals is provided. An array of an arbitrary number of sound sensors positioned in an arbitrary configuration receives the sound signals from multiple disparate sources. The sound signals comprise the target sound signal from a target sound source, and ambient noise signals. A sound source localization unit, an adaptive beamforming unit, and a noise reduction unit are in operative communication with the array of sound sensors. The sound source localization unit estimates a spatial location of the target sound signal from the received sound signals. The adaptive beamforming unit performs adaptive beamforming by steering a directivity pattern of the array of sound sensors in a direction of the spatial location of the target sound signal, thereby enhancing the target sound signal and partially suppressing the ambient noise signals, which are further suppressed by the noise reduction unit.

    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.
