Abstract: A method for self-calibrating a sound pickup process that uses a microphone array in a wearable device that also includes a loudspeaker, where the microphone array being in a physical arrangement with respect to the loudspeaker. The method obtains, for each of several microphones of the microphone array, one or more transfer functions that each represent a response of the microphone to sound from a position in an acoustic space. The method determines whether a physical arrangement of the microphone array with respect to the loudspeaker has changed and adjusts the transfer function, for at least one of the microphones of the several microphones, in response to determining that the current physical arrangement of the microphone array with respect to the loudspeaker has changed.

Abstract: A method for routing audio content through an electronic device that is to be worn by a user. The method obtains a communication and determines whether the communication is private. In response to determining that the communication is private, the method drives a bone conduction transducer of the electronic device with an audio signal associated with the communication. In response to determining that the communication is not private, however, the method drives a speaker of the electronic device with the audio signal.

Abstract: An audio system having a depth capturing device and a microphone array to respectively detect a point cloud and a local sound field, is described. The point cloud includes points corresponding to objects in a source space, and the local sound field includes sounds received in respective directions from the source space. The audio system includes one or more processors to generate a global sound field based on distances to the points and directions of the sounds. The global sound field includes virtual sound sources emitting respective sounds at respective points. A speaker can render the virtual sound sources to a user in a virtual space that corresponds to the source space.

Abstract: An audio appliance can include a microphone transducer configured to receive sound from an environment and to convert the received sound into an audio signal and a display. The audio appliance can include an audio analytics module configured to detect an audio-input impairment by analyzing the audio signal and output a detection signal identifying the audio-input impairment in real-time. The audio-input impairment can include, for example, a poor-intelligibility impairment, a microphone-occlusion impairment, a handling-noise impairment, a wind-noise impairment, or a distortion impairment. The audio appliance can also include an impairment module configured to identify and emit a user-perceptible alert corresponding to the identified audio-input impairment in real-time; and an interactive guidance module configured to present a suggested action to address the audio-input impairment in real-time. Related aspects also are described.

Abstract: A microphone array included in a portable electronic device is used to generate various virtual studio microphones by combining one or more microphone signals to produce one or more acoustic pickup beams. An error is determined in a position of the microphone array relative to an audio source to be recorded. An interface is displayed to instruct a user on repositioning the microphone array relative to the instrument and the instrument is recorded using the repositioned microphone array.

Abstract: A conversation detector processes microphone signals and other sensor signals of a headphone to declare a conversation and configures a filter block to activate a transparency audio signal. It then declares an end to the conversation based on processing one or more of the microphone signals and the other sensor signals, and in response deactivates the transparency audio signal. The conversation detector monitors an idle duration in which an OVAD and a TVAD are both or simultaneously indicating no activity and declares the end to the conversation in response to the idle duration being longer than an idle threshold. Other aspects are also described and claimed.

Abstract: Acoustic pickup beams (sound beams) can be formed in a physical environment from a plurality of microphone signals. Each of the sound beams can measure acoustic energy in a direction of the respective sound beam. Directional decay of the acoustic energy measured through each of the sound beams is determined. Room surface acoustic properties of the physical environment are determined based on mapping the directional decay of the acoustic energy to the physical environment. Other aspects are described and claimed.
