Abstract: Technologies pertaining to calibration of filters of an audio system are described herein. A mobile computing device is configured to compute values for respective filters, such as equalizer filters, and transmit the values to a receiver device in the audio system. The receiver device causes audio to be emitted from a speaker based upon the values for the filters.

Abstract: The techniques discussed herein may facilitate real-time computation and playback of a propagated signal(s) perceived at a listener location in a three-dimensional environment in response to reception of a desired anechoic signal at a source location in the three-dimensional environment. The propagated audio realistically accounts for dynamic signal sources, dynamic listeners, and effects caused by the geometry and composition of the three-dimensional environment. The techniques may parameterize impulse response(s) of the environment and convolve the anechoic signal with canonical filters at run-time in a manner that respects the parameters of the parameterized impulse response(s). The techniques also provide for real-time computation and playback of a propagated audio signal perceived at a listener location in a virtual three-dimensional environment responsive to generation of source audio signals generated at multiple source locations in the virtual three-dimensional environment.

Abstract: Technologies pertaining to provision of customized audio to each listener in a plurality of listeners are described herein. A sensor outputs data that is indicative of locations of multiple listeners in an environment. The data is processed to determine locations and orientations of the respective heads of the multiple listener in the environment. Based on the locations and orientations of heads of the listeners in the environment, for each listener, respective customized audio signals are generated. The customized audio signals are transmitted to respective beamforming transducers. The beamforming transducers directionally output customized beams for the first listener and the second listener based upon the customized audio signals and locations of the heads of the listeners.

Abstract: Technologies pertaining to improving an auditory experience of a listener are described. Audio is modified based upon noise generated by noise sources in an environment. A microphone generates a signal that is representative of noise in the environment, and the signal is processed to identify peak frequencies therein. When a key frequency of the audio is proximate to a peak frequency in the noise, the audio is modified to improve the listener's perception of the audio.
