Abstract

The invention provides an audio detection method and device and terminal equipment, and is suitable for the field of software acoustic testing, and the method comprises the steps: obtaining a sweep frequency signal in a preset frequency range, carrying out the sound card driving of the sweep frequency signal, obtaining a test sound, receiving an audio signal recorded by to-be-detected equipment, and transmitting the audio signal to the to-be-detected equipment. The audio signal is obtained by recording the test sound through a microphone of a device to be detected, performing frequency conversion processing on the audio signal to obtain a first frequency decibel curve, performing Gaussian filtering processing on the first frequency decibel curve to obtain a second frequency decibel curve, and outputting the second frequency decibel curve to the device to be detected. And performing threshold detection on the second frequency decibel curve to obtain an audio detection result of the to-be-detected equipment. The invention further provides an audio detection device and terminal equipment. The problem of inaccurate audio detection can be solved.

Description

technical field [0001] The application belongs to the technical field of software acoustic testing, and in particular relates to an audio detection method, device and terminal equipment. Background technique [0002] With the development of technology, it is more and more important to perform audio detection on different audio devices, for example, to perform audio detection on devices such as Bluetooth headsets and speakers. In the prior art, the audio signal is collected mainly through a down-sampling method to draw a decibel curve, and the audio detection is performed by setting the frequency response threshold of the curve. Among them, due to the large number of audio signals in the curve, and the electrical noise and external noise when collecting data exist objectively. Therefore, it is difficult to restore the change trend of the decibel curve if the sampling point is just abnormal by using the method of downsampling, and it is difficult to correctly set the frequenc...
