摘要： The various implementations described herein include methods, devices, and systems for automatic audio equalization. In one aspect, a method is performed at an electronic device that includes speakers, microphones, processors and memory. The electronic device outputs audio user content from the speakers and automatically equalizes subsequent audio output of the device without user input. The automatic equalization includes: (1) obtaining audio content signals, including receiving outputted audio content at each microphone; (2) determining from the audio content signals phase differences between microphones; (3) obtaining a feature vector based on the phase differences; (4) obtaining a frequency correction from a correction database based on the obtained feature vector; and (5) applying the obtained frequency correction to the subsequent audio output.

摘要： A method for detecting failure of vehicle is provided. The method obtains noise data of the vehicle from microphone units. The microphone units are arranged on different positions of the vehicle. The method detects sets of coordinate data of noise sound sources which is determined according to the noise data. The sets of coordinate data of the noise sound sources are relative sets of coordinate data. The method detects a noise type of each noise sound source according to the noise data. The method matches the sets of coordinate data and a modeled image of the vehicle, to determine an absolute coordinate data of each noise sound source in the vehicle. The method determines failure parts of the vehicle according to the noise type of each noise sound source and the absolute coordinate data. A related electronic device and a related non-transitory storage medium are provided.

摘要： A method is given for a broadband constant beam width acoustic array using shading function parameters for a three dimensional axially symmetric beam. Coefficients are calculated for an estimated shading function fitting the parameters that is a summation of Legendre polynomial orders. The number of orders is user specified. Null bearing locations can be determined from the parameters or from the shading function. A constant beam width shading function can be created from these parameters and used as amplifications and attenuations for a conical spherical array of transducers. The array can be truncated at the null bearing locations. The estimated shading function can be further refined by provided additional Legendre polynomial orders.

摘要： In an example, a computing device includes a microphone array and a processor. The processor may transmit an audio stream of a presentation to an online conference. Further, the processor may receive audio data via the microphone array while the audio stream is being transmitted. In response to determining the audio data is coming from a presenter of the presentation, the processor may perform a fade audio operation to control an audio level of the audio stream.

摘要： The present disclosure relates to a device for processing an audio signal. The device may include a first acoustic-electric transducer and a second acoustic-electric transducer. The first acoustic-electric transducer may have a first frequency response, and may be configured to detect the audio signal and generate a first sub-band signal according to the detected audio signal. The second acoustic-electric transducer may have a second frequency response, the second frequency response being different from the first frequency response. The second acoustic-electric transducer may be configured to detect the audio signal and generate a second sub-band signal according to the detected audio signal.

摘要： A remote distress monitor includes a steerable microphone array, a memory, and a control system. The steerable microphone array is configured to detect audio data and generate sound data. The memory stores machine-readable instructions. The control system includes one or more processors configured to execute the machine-readable instructions. The generated sound data from the steerable microphone array is analyzed. Based at least in part on the analysis, a token associated with the audio data detected by the steerable microphone array is generated. The audio data is representative of one or more sounds associated with a distress event. The generated token is transmitted, via a communications network, to an electronic device to cause a distress response action to occur. The distress response action is associated with the distress event.

Typically, the hardware processor in at least one device d1 from among the devices controls d1's speaker to at least once broadcast a first signal (e.g. “localization request signal”) at a time t_zero. Typically the hardware processor in device d1 at least once computes at least one of angle and distance between d2 and d1, to monitor locations of other group members who may be on the move.
