  • Patent number: 11317234
    Abstract: A method for spatialized sound reproduction using an array of loudspeakers, to generate a chosen sound field selectively audible in a first predetermined sub-area of an area covered by the loudspeakers, the area further including a second sub-area in which the chosen sound field is inaudible. The loudspeakers are supplied with respective control signals so that each one continuously emits an audio signal. The method includes, iteratively and continuously: estimating a sound pressure in the second sub-area as a function of the respective control signals of the loudspeakers, and of a respective initial weight of the control signals; calculating an error between the estimated sound pressure and a target sound pressure in the second sub-area; and, calculating and applying respective weights to the control signals, based on the error. The sound pressure in the second sub-area is calculated again based on the respective weighted control signals of the loudspeakers.

  • Patent number: 11304001
    Abstract: A method for detecting wind using a microphone and a speaker of an electronic device. The method obtains a microphone signal produced by the microphone. The method obtains a speaker input signal produced by the speaker that is emulating a microphone capturing ambient sound in an environment through the speaker. The method determines a coherence between the microphone signal and the speaker input signal and determines whether the coherence is below a coherence intensity threshold. In response to determining that the coherence is below the coherence intensity threshold, the method determines a presence of wind in the environment.

The audio system generates a set of test locations using the initial set of HRTFs. The audio system presents test sounds at each of the initial set of test locations using the initial set of HRTFs. The audio system monitors user responses to the test sounds. The audio system uses the monitored responses to generate a new set of estimated HRTFs and a new set of test locations. The process repeats until a threshold accuracy is achieved or until a set period of time expires. The audio system presents audio content to the user using the customized HRTFs.

In such a manner, a facilitating method for sound engineering mixing adjustments that provide such accommodations are provided for improved sound recordings for distribution within on-line or recording product frameworks.

  • Patent number: 10871543
    Abstract: A system that handles direction of arrival (DOA) estimation for acoustic signals using sub-array selection, identifies a plurality of microphone sub-arrays from the plurality of microphones in the microphone-array, selects a set of microphone sub-arrays from the plurality of microphone sub-arrays, and computes a relative time-delay for arrival of the acoustic signals between each pair of microphones of the selected set of microphone sub-arrays. The selection is based on a maximum distance between each pair of microphones of the identified plurality of microphone sub-arrays of the microphone-array. A first microphone sub-array is determined from the selected set of microphone sub-arrays and the DOA of the acoustic signals is estimated with reference to the determined first microphone sub-array. The estimation of the direction of arrival of the acoustic signals is based on the computed relative time-delay for the determined first microphone sub-array of the microphone-array.
