    Abstract: An audio enhancement method includes receiving a first input signal representative of audio captured using an array of two or more sensors, the first input signal characterized by a first signal-to-noise ratio (SNR), with the audio being the signal-of-interest. The method also includes receiving a second input signal representative of the audio, the second input signal characterized by a second SNR. The second SNR is higher than the first SNR. The method further includes computing a spectral mask based on a frequency domain representation of the second input signal, and processing a frequency domain representation of the first input signal based on the spectral mask to generate one or more driver signals. The method further includes driving one or more acoustic transducers using the generated driver signals.

    Abstract: The technology described in this document can be embodied in a method of reproducing audio related to a teleconference between a second location and a remote first location. The method includes receiving data representing audio captured by a microphone array disposed at the remote first location. The data includes directional information representing the direction of a sound source relative to the remote microphone array. The method also includes obtaining, based on the directional information, information representative of head-related transfer functions (HRTFs) corresponding to the direction of the sound source relative to the remote microphone array, and generating, using one or more processing devices, an output signal for an acoustic transducer located at the second location. The output signal is generated by processing the received data using the information representative of the one or more HRTFs, and is configured to cause the acoustic transducer to generate an audible acoustic signal.
