  • Patent number: 11240621
    Abstract: 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.

  • Patent number: 9418675
    Abstract: A method and a wearable communication system for personal face-to-face and wireless communications in high noise environments are provided. A noise cancellation device (NCD) operably coupled to a wireless coupling device (WCD) includes a speech acquisition unit, an audio signal processing unit, one or more loudspeakers, and a communication module. The NCD receives voice vibrations from user speech via a contact microphone and a second microphone and converts the voice vibrations into an audio signal. The NCD processes the audio signal to remove noise signals and enhance a speech signal contained in the audio signal. A loudspeaker emits the speech signal during face-to-face communication. The NCD transmits the speech signal to a communication device via the WCD and receives an external speech signal from the communication device during wireless communication. With the NCD, the signal intelligibility and signal-to-noise ratio can be improved, for example, from ?10 dB to 20 dB.

  • Patent number: 9131305
    Abstract: 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.

  • Patent number: 8861756
    Abstract: 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.

  • Patent number: 8655068
    Abstract: A color correction system includes an identical first color chart (FCC) and a second color chart (SCC), and a color correction unit (CCU). The FCC and the subject are positioned in view of a source image capture device (SICD) at a source location. The SCC and a display unit are positioned in view of a destination image capture device (DICD) at the destination location. The SICD captures and transmits source image content (SIC) of the subject and the FCC to the CCU at the destination location via a network. The DICD captures destination image content (DIC) of the SCC and the SIC displayed on the display unit. The CCU generates calibration parameters by comparing the FCC extracted from the SIC and/or the DIC, with the SCC extracted from the DIC, and corrects the SIC of the subject and gamma parameters on the display unit using the generated calibration parameters.

  • Patent number: 8359195
    Abstract: A method and device for processing signals representing speech or audio via a plurality of filters that approximate behaviors of the basilar membrane of human cochlea. Each of the plurality of filters is formed from a mother filter via the dilation and a shift in time and has the similar impulse response of the basilar membrane to the frequency band for which the filter represents. Any process can be conducted and any feature can be extracted in the domain of the filters' outputs for applications, such as noise reduction, speech synthesis, coding, and speech and speaker recognition. Processed signals can be synthesized back to the time domain via an inverse cochlear transform.
