[0004] Option 2. Using machine learning, the testing equipment trains different audio signals output by different devices under test, and compares the audio with the model obtained through training, so as to determine whether the audio signal output function of the device under test is normal. The scheme requires a lot of training and has high requirements for the computing and storage resources of the testing equipment. For testing equipment using a single-chip microcomputer, this type of scheme is difficult to use in the testing equipment, which makes the scheme unable to be widely promoted. At the same time, With the continuous update of digital signal technology, frequent retraining is required to increase the training results of new audio signals, which also increases the training cost of audio signals

[0055] Figure 2a It is a flowchart of an audio detection method provided by Embodiment 2 of the present invention. The method provided in this embodiment is embodied on the basis of the foregoing embodiments. Specifically, refer to Figure 2a , the audio detection method provided in this embodiment specifically includes:

[0056] S210. Acquire the audio signal to be tested output by the device to be tested.

[0057] S220. Divide the audio signal to be tested into multiple audio frames to be tested.

[0058] Since the audio signal to be tested and the standard audio signal are independently sampled and obtained, even if the audio signal output function of the device under test is normal, there is no guarantee that the phase of the sampled data in the audio signal to be tested at the same sampling time is exactly the same as that of the standard audio signal. In the subsequent comparison operation, it is impossible to compare each sampling point one by one. Therefore, in t...

Abstract

The invention discloses an audio detecting method, an audio detecting device, audio detecting equipment and a storage medium, wherein the audio detecting method comprises the steps of acquiring a to-be-detected audio signal output from to-be-detected equipment; calculating the frequency domain energy value of the to-be-detected audio signal; comparing the frequency domain energy value of the to-be-detected audio signal with the frequency domain energy value of a standard audio signal, and determining whether an audio signal output function of the to-be-detected equipment is normal according to a comparing result. The audio detecting method can optimize an existing audio detecting solution and simply and efficiently realizes detecting for the audio signal output function, wherein in calculating the frequency domain energy value of the to-be-detected audio signal, frame separating processing is performed on the to-be-detected audio signal, and the frequency domain energy value of each to-be-detected audio frame is calculated. Furthermore when the frequency domain energy value of the to-be-detected audio signal is compared with the frequency domain energy value of the standard audio signal, time shifting processing is performed for ensuring a fact that a final obtained comparing result can ensure a time domain characteristic and a frequency domain characteristic.

Description

technical field [0001] The present invention relates to the technical field of signal processing, in particular to an audio detection method, device, equipment and storage medium. Background technique [0002] Generally speaking, a device with an audio signal output function will be tested for the audio signal output function before leaving the factory, so as to ensure that the audio signal output function of the factory device is normal. When testing the audio signal output function of the device under test, the following two types of solutions are usually used: [0003] Solution 1: Self-made an audio signal with a fixed output frequency as the audio output signal, and the detection equipment calculates the energy of the audio output signal output by the device under test, and judges whether the audio output signal is accurate by determining the energy ratio at the output frequency , and then determine whether the audio signal output function of the device under test is no...
