  • Patent number: 10051400
    Abstract: A method of outputting audio in a teleconferencing environment includes receiving audio streams, processing the audio streams according to information regarding effective spatial positions, and outputting, by at least three speakers arranged in more than one dimension, the audio streams having been processed. The information regarding the plurality of effective spatial positions corresponds to a perceived spatial scene that extends beyond the speakers in at least two dimensions. In this manner, participants in the teleconference perceive the audio from the remote participants as originating at different positions in the teleconference room.

  • Publication number: 20180018984
    Abstract: Example embodiments disclosed herein relate to assessment and adjustment for an audio environment. A computer-implemented method is provided. The method includes obtaining a first audio signal captured by a device located in an environment. The method also includes analyzing a characteristic of the first audio signal to determine an acoustic performance metric for the environment. The method further includes, in response to the acoustic performance metric being below a threshold, providing a first task for a user to perform based on the characteristic of the first audio signal. The first task is related to an adjustment to a setting of the environment. Embodiments in this regard further provide a corresponding computer program product. Corresponding system and computer program product are also disclosed.

  • Publication number: 20140278380
    Abstract: In some embodiments, a method for modifying noise captured at endpoints of a teleconferencing system, including steps of capturing noise at each endpoint, and modifying the captured noise to generate modified noise having a frequency-amplitude spectrum which matches a target spectrum and a spatial property set which matches a target spatial property set. In other embodiments, a teleconferencing method including steps of: at endpoints of a teleconferencing system, determining audio frames indicative of audio captured at each endpoint, each of a subset of the frames indicative of noise but not a significant level of speech; and at each endpoint, generating modified frames indicative of modified noise having a frequency-amplitude spectrum which matches a target spectrum and a spatial property set which matches a target spatial property set, and generating encoded audio including by encoding the modified frames. Other aspects are systems configured to perform any embodiment of the method.

  • Patent number: 8705781
    Abstract: The present application discloses methods, systems, and hearing prostheses for reducing wind noise and/or thermal noise in an audio signal transmitted to the user of a hearing prosthesis. A method in accordance with the present disclosure includes utilizing delay-sum beamforming to improve the signal-to-noise ratio in an audio signal that contains wind noise and/or thermal noise. In the presence of at least one of wind noise and thermal noise, amplitudes and phases of at least two input signals are matched. The two signals are then added together, resulting in an average improvement in the signal-to-noise ratio of the signal transmitted to the user of about 3 dB.

  • Patent number: 8417349
    Abstract: Methods and systems are disclosed for rate matching in a stimulating medical device, such as a cochlear implant or an auditory brain stimulator. In embodiments, the stimulating medical device applies a fast Fourier transform (FFT) at an analysis rate to the received signal to obtain a plurality frequency bin output signals. The stimulating medical device then applies a rate matching through interpolation function to the frequency bin output signals to match the stimulation rate for the stimulating medical device. This rate matching through interpolation function may apply a common interpolation filter to each frequency bin output to obtain a plurality of outputs distributed in time across the time period between executions of the FFT. The values of the frequency bin output signals at the time most closely matching the time for which stimulation is to be applied may then be selected and used in applying the stimulation.
