As shown in fig. 1, an embodiment of the present application provides a method for performing self-test by using an audio device under test itself, where the method is applied to the audio device under test, and the method includes:

s100, configuring an automatic test program in the audio equipment to be tested in advance.

Illustratively, the audio device under test executes the automatic test program to test the audio device under test while the test is being performed.

S200, the audio device to be tested is switched to a test mode (for example, the audio device to be tested in this embodiment is a device before a manufacturer leaves a factory, so that the test mode in which the audio device to be tested is located may be a default mode before the manufacturer leaves the factory, so as to facilitate testing), so as to run the automatic test program to implement the following test steps:

s210, playing the test audio through the playing device of the audio equipment to be tested.

For example, when the audio device under test is switched to the test mode on the audio device production line, the playing device (e.g., a speaker) of the audio device under test may be automatically activated to play the pre-configured test audio according to the configuration of the automatic test program.

And S220, recording through the recording device of the audio equipment to be tested to obtain recorded audio.

For example, while the test audio is being played, the recording device (e.g., microphone array) of the audio device under test may be started synchronously with the configuration of the automatic test program. Illustratively, the automatic test program may be an integrated driver layer sub-program unit for determining a microphone array for sound pickup, recording and storage.

And S230, analyzing the recorded audio by the audio equipment to be tested according to the automatic test program so as to test the audio equipment to be tested.

According to the embodiment of the application, the operation performance and the hardware configuration of the device to be tested are fully utilized, the device to be tested plays the test sound source, the audio is recorded, the test software is executed to realize analysis and test, and the dependence of the test on external equipment is greatly reduced. Only software is needed as a test fixture, the cost is saved obviously, and each device to be tested can independently test by itself without depending on external test equipment, so that large-batch synchronous tests can be realized.

As shown in fig. 2, in some embodiments, the sound recording apparatus includes a microphone array formed by a plurality of microphones; the recorded audio comprises multi-path sub-recorded audio recorded by the plurality of microphones;

The audio equipment to be tested analyzes the recorded audio according to the automatic test program, so that the test on the audio equipment to be tested comprises the following steps:

s231, analyzing the sub-recorded audio of each path respectively to realize the test of each microphone;

and S232, carrying out comparative analysis on the multi-channel sub-recorded audio to realize the test of a microphone array formed by the plurality of microphones.

In this embodiment, each sub-recorded audio is referred to as "each channel data", and is referred to as audio data recorded by each MIC; this embodiment is particularly directed to intelligent audio devices with microphone arrays, which have at least one and two microphones, each of which records data called a Channel (Channel), e.g., a four MIC array, and which, when recorded, can obtain data for 4 channels.

The recorded audio data is automatically recorded after the driver layer calls the MIC array of the device to be tested and executes the recording command through the test program in the embodiment of the application, and is stored in the designated path directory.

According to the embodiment of the application, by acquiring the data of each channel, on one hand, the function of each MIC channel can be ensured to be normal through testing; on the other hand, the test needs to be evaluated to ensure that the performance difference of each MIC meets the requirement. For audio equipment with an MIC array, in use, an important function is to determine a sound source by calculating a difference between data of each MIC channel (for example, when an intelligent sound device is used, the intelligent sound device can calculate in which direction a user speaks), so that the equipment to be tested needs to ensure that the performance of each MIC channel is consistent.

As shown in fig. 3, in some embodiments, the performing a comparative analysis on the multi-channel sub-recorded audio to perform a test on a microphone array formed by the plurality of microphones includes:

s2321, respectively calculating a plurality of amplitudes of each path of sub-recorded audio on a plurality of frequency points.

Illustratively, the recorded audio data of each channel is stored in digital binary, taking the case of 16-bit data as an example: converting the 16-bit data into 10-system data, and dividing the data by 215 to obtain a ratio which is used as the audio amplitude of the whole sampling point; and selecting a corresponding section, as shown in fig. 4, one frequency point, and counting all amplitudes of the frequency points in the time domain, wherein the maximum absolute value between two 0 points is the amplitude of the frequency band.

The amplitude value in table 1 below is calculated for each frequency point of each channel:

TABLE 1

Frequency point/channel	CH1	CH2	…	CHn
					200Hz	0.5	0.5	…	0.5
300Hz	0.6	0.6	…	0.6
					…	…	…	…	…
5000Hz	0.7	0.7	…	0.7
					…	…	…	…	…
8KHz	0.8	0.8	…	0.8

For example, separately determining whether the microphone corresponding to each channel is abnormal according to the measured amplitudes of different frequency points may be: in a group of test data, the amplitudes calculated by the CH1 at 200 Hz-8 KHz are all about 0.1 (much smaller than the amplitude range of other channels of 0.5-0.8), and the state of the CH1 channel is judged to be abnormal.

As shown in table 1 above, the data of the same frequency point of each channel are compared transversely to make a difference, and the fluctuation range difference does not exceed ± 1.5 dB.

S2322, comparing and analyzing amplitudes of the sub-recorded audio in each frequency point in the multiple frequency points to obtain multiple amplitude difference value sets, wherein each amplitude difference value set corresponds to two paths of the multiple paths of recorded audio and comprises multiple amplitude difference values;

s2323, comparing the amplitude difference value groups with a preset threshold value to determine whether the microphones are abnormal.

For example, when a 4MIC linear array recording device is tested, waveforms recorded in each channel are as shown in fig. 5, and are respectively 1 to 4 channels from top to bottom, and the amplitude of the 2 nd channel is found to be smaller by calculating the recording amplitude of each channel corresponding to the test frequency point as shown in table 2 below and comparing the calculated values. If the threshold value is exceeded, the channel MIC equipment can be judged to be abnormal, and the condition that the assembly deviation causes the blocking of the sound receiving hole or the foreign matter exists in the sound receiving hole can be further confirmed.

TABLE 2

	Channel 1	Channel 2	Channel 3	Channel 4
					Frequency point 1	0.08	0.05	0.09	0.08
Frequency point 2	0.09	0.06	0.08	0.09
					…	…	…	…	…
Frequency point n	0.08	0.05	0.09	0.09

And uploading the test data to the cloud end through the equipment to be tested, accumulating a large amount of production test data, continuously optimizing an intelligent test algorithm for follow-up, and accumulating original data for intelligent production and manufacturing.

In some embodiments, the comparing according to the plurality of sets of amplitude differences with a preset threshold to determine whether there is an anomaly in the plurality of microphones comprises:

respectively comparing the amplitude difference values in each amplitude difference value group with a preset threshold value;

and when a plurality of amplitude difference values larger than the preset threshold value exist in a certain amplitude difference value group, determining that the two microphones corresponding to the certain amplitude difference value group have abnormity.

The preset threshold value in the embodiment of the application is determined according to the maximum value of the amplitude difference value of the audio data recorded by the two microphones on the same frequency point under the normal condition.

In this embodiment, only when there are a plurality of (rather than only one) amplitude differences in the current amplitude difference set that are greater than the preset threshold, it is determined that there is an abnormality in the two microphones corresponding to the current amplitude difference set. Therefore, the occurrence of misjudgment caused by the accidental phenomenon of spike pulse caused by signal interference or other unstable factors possibly existing in the actual test is avoided.

Spikes caused by such signal interference or other instability factors are short and occasional and are almost impossible to occur simultaneously at multiple different frequency points of the data collected by the same microphone. Therefore, the accuracy and reliability of the analysis and judgment result of the method of the embodiment of the application are ensured.

In some embodiments, said comparing the plurality of sets of amplitude differences to a preset threshold to determine whether an anomaly exists in the plurality of microphones comprises:

summing the amplitude differences in each amplitude difference group to obtain a plurality of difference sums corresponding to each amplitude difference group;

respectively comparing the difference values with the preset threshold value;

and judging that the difference value larger than the preset threshold value and the two corresponding microphones have abnormity.

The preset threshold value in the embodiment of the application is determined according to at least twice of the maximum value of the amplitude difference value of the audio data recorded by the two microphones on the same frequency point under the normal condition. To achieve the same effect as in the previous embodiment: misjudgment caused by contingency is avoided, and the accuracy and reliability of the analysis judgment result of the method of the embodiment of the application are ensured.

Fig. 6 is a flowchart illustrating another embodiment of the self-test method using the audio device under test itself according to the present application. The test is started by clicking, the device to be tested starts to play a special audio signal, and simultaneously the device to be tested starts to record audio to obtain original audio data (namely, recorded audio data), wherein the original audio data comprises multi-path recorded audio data collected by a plurality of microphones. The intelligent test software calls the original audio data, calculates key parameters such as amplitude values and the like for the recorded audio data of each channel (each path), calculates the difference of the amplitude values among the channels, and judges whether the MIC function is normal or not. The results of each part are directly displayed on the screen, so that the positioning problem of workers is conveniently, timely and quickly helped.

In addition, the difference result data of the amplitudes of the channels are uploaded to the cloud for optimizing the intelligent algorithm. Illustratively, the parameter fluctuation thresholds S1 are set according to design targets. And introducing S1 as a standard fluctuation threshold value into a production line production test, testing n products D1-Dn to be tested to obtain n groups of test data, summarizing abnormal states of the products, and associating the abnormal states with the test data. When the production line has similar test data sets again, the test system pushes recommended troubleshooting steps and solutions to production line staff, and production efficiency is improved.

The test method of the embodiment of the application only needs to use existing functional equipment of the equipment to be tested, does not need to additionally increase a test device, is closer to the actual use scene of the equipment compared with a traditional test method, enables the test result to be more accurate, reduces the dependence of the test on high-end external equipment, can greatly reduce the production test cost, and improves the production test efficiency.
