Abstract

The invention provides a microphone array detection method and device. The method comprises the steps: obtaining an audio signal obtained after a microphone array collects a test audio, and enabling the frequency of the test audio to cover each frequency point in a preset frequency range; decoding the audio signal to obtain an audio sub-signal corresponding to each microphone in the microphone array; extracting at least one piece of to-be-detected parameter information of each audio sub-signal; and comparing at least one piece of to-be-detected parameter information of each audio sub-signal with corresponding standard parameter information in a preset configuration file, and determining a detection result of the microphone array. The method can automatically perform anomaly detection on the audio signal processed by the front end of the microphone array product without manual participation, thereby reducing the labor cost, and improving the detection efficiency of the microphone arrayproduct. Therefore, the detection efficiency is improved, the method can be suitable for batch detection, and the production efficiency can be ensured.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular to a method and device for detecting a microphone array. Background technique [0002] The current microphone array product, when performing nonlinear detection, manually obtains the output signal after the front-end processing of the microphone array product, imports it into an audio analysis tool, obtains the time domain signal and frequency domain signal, and then manually analyzes whether there is spectral distortion, signal clipping, etc. Abnormal situations such as width. However, in the above solution, the labor cost is high, the detection efficiency is low, and it is difficult to be used for batch detection, and it is difficult to ensure the production efficiency. Contents of the invention [0003] The purpose of this application is to solve one of the above-mentioned technical problems at least to a certain extent. [0004] For this reason, the fir...
