[0047] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0048] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0049] The main solution of the present application is to obtain a test file, which is obtained by recording a test process of an audio test file in a device under test; read the test file, obtain the audio playback click moment and monitor the loudness and frequency of the test file; when the loudness and the frequency reach preset values, determine the audio response moment; and determine the audio playback response time according to the audio playback click moment and the audio response moment.

[0050] Currently, vehicle system response tests usually determine the vehicle computer response time through subjective evaluation by the tester, which has poor accuracy. Therefore, how to improve the accuracy of the vehicle cabin audio playback response time test is a problem that still needs to be solved.

[0051] This application improves the accuracy of the vehicle cabin audio playback response time test by detecting the loudness of the audio and the frequency mutation moment to test the audio playback response time.

[0052] Based on this, the embodiment of the present application provides a method for testing the response time of the audio playback in the vehicle cabin, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the method for testing the response time of vehicle cabin audio playback according to the present application.

[0053] In this embodiment, the vehicle cabin audio playback response time testing method includes steps S10 to S40:

[0054] Step S10: Acquire a test file, wherein the test file is obtained by recording a test process of the audio test file in the device under test;

[0055] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a vehicle cockpit audio playback response time test device, etc. The following takes the vehicle cockpit audio playback response time test device as an example to illustrate this embodiment and the following embodiments.

[0056] It is understandable that when testing the audio playback response time, the two most important data are the play click moment and the actual audio playback moment. Therefore, it is necessary to obtain a test file, wherein the test file is obtained by recording the test process of the audio test file in the device under test. The play click moment and the actual audio playback moment can be obtained through the test file. During the test, it is necessary to prepare the test environment in advance and arrange the decibel detector and frequency detector reasonably to clearly capture the loudness and frequency of the audio signal. And perform background denoising on the test file to improve the test accuracy.

[0057] Step S20: reading the test file, obtaining the audio playback click time and monitoring the loudness and frequency of the test file;

[0058] It is understandable that the audio playback click moment can be directly obtained from the test file, while the audio response moment needs to obtain the loudness and frequency first. Specifically, the audio playback click moment and the changes in loudness and frequency can be obtained through millisecond-level high-precision frame capture software.

[0059] In a feasible manner, the steps of reading the test file, obtaining the audio playback click time and monitoring the loudness and frequency of the test file include:

[0060] Read the test file, and obtain the audio playback click time according to the video content in the test file;

[0061] The loudness and frequency of the test file are monitored according to the audio content in the test file.

[0062] It is understandable that the test file contains the process of audio playback clicks, so the audio playback click moment can be directly obtained through the video content in the test file. And according to the audio content in the test file, the changes in the loudness and frequency of the test file can be obtained.

[0063] Step S30: When the loudness and the frequency both reach preset values, determining the audio response time;

[0064] It is understandable that after the audio responds, there will be a sudden change in both loudness and frequency, thereby obtaining an accurate audio response moment.

[0065] In a feasible manner, when the loudness and the frequency both reach preset values, the step of determining the audio response time includes:

[0066] When the loudness reaches the preset loudness value first, the moment when the frequency reaches the preset frequency value is determined as the audio response moment;

[0067] When the frequency reaches the preset frequency value first, the moment when the loudness reaches the preset loudness value is determined as the audio response moment.

[0068] It is understandable that, in order to ensure the accuracy of the audio response time, when one of the two indicators of loudness and frequency reaches the preset value first, the time when the other indicator reaches the preset value is used as the audio response time.

[0069] Step S40: determining the audio play response time according to the audio play click time and the audio response time.

[0070] It is understandable that after obtaining the audio play click time and the audio response time, the audio play response time can be calculated. Specifically, it can be obtained by subtracting the audio play click time from the audio response time. In order to ensure the accuracy of the data, the average of multiple test results can be used as the final audio play response time.

[0071] This embodiment obtains a test file, which is obtained by recording a test process of an audio test file in a device under test; reads the test file, obtains an audio playback click moment, and monitors the loudness and frequency of the test file; when the loudness and the frequency both reach preset values, determines an audio response moment; and determines an audio playback response time according to the audio playback click moment and the audio response moment.

[0072] In summary, this embodiment improves the accuracy of the vehicle cabin audio playback response time test by detecting the loudness of the audio and the frequency mutation moment to test the audio playback response time.

[0073] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 2 , step S10 also includes steps S101 to S102:

[0074] Step S101: executing a test operation on the device under test using the audio test file, wherein the test operation includes playing audio, pausing audio, and switching audio;

[0075] It is understandable that the preset values ​​of loudness and frequency should be the sudden changes in loudness and frequency when the audio file is played as the preset values, so an audio file with a single frequency and fixed loudness can be selected as the audio test file, then the preset value can be directly determined by the frequency and loudness of the audio file to ensure the accuracy of the test.

[0076] Step S102: obtaining a test file by recording the operation process.

[0077] It is understandable that when testing the audio response time, the response time of audio playback, pause and switching can be tested separately to ensure the accuracy of the test. And to ensure that the playback process is not affected by other factors, the audio playback mode can be set to no fade-in and fade-out. At the same time, the playback response time test can also be performed under different connection methods in the vehicle infotainment system (such as built-in music software, USB connection, and hand-car interconnection). In the specific test, the test can be carried out through manual testing and automated testing environment. It can be selected according to the required test accuracy, human, material and financial resources and other factors. The test process can be referred to. Figure 3, manual testing is performed by testers. The first step is test preparation. Standard test audio files that can be accurately loaded on multiple devices (handcar interconnection) are required, and decibel detectors and frequency detectors are reasonably arranged in the cockpit to be tested; then the test operation process, testers perform operations such as playing, switching songs, pausing, etc. on multiple terminals, and use mobile devices such as mobile phones and cameras to record the operation process. Automated platform testing requires the import of test cases. First of all, test preparation is also required. Standard test audio files are built into the automated test platform, and decibel detectors and frequency detectors are deployed in the automated test environment; then the test operation process, the automated platform runs the audio operation test cases and records the operation process through the equipped monitor. Whether it is manual testing or automated platform testing, after obtaining the recording file, it is necessary to denoise the background of the recording file and capture the key frames in order to calculate the response time. The advantages of manual testing are flexible operation and low cost, but the disadvantages are low accuracy and inability to perform batch testing. The advantages of automated platform testing are high test accuracy and batch operation, and the disadvantages are high cost and need to provide personnel training. In practice, the best test path can be selected according to test requirements and cost constraints.

[0078] In this embodiment, the audio test file performs a test operation in the device under test, wherein the test operation includes playing audio, pausing audio, and switching audio; and the test file is obtained by recording the operation process.

[0079] In summary, in this embodiment, an audio file with fixed loudness and single frequency is selected for testing to obtain a test file, thereby improving the accuracy of the vehicle cabin audio playback response time test.

[0080] For example, in order to help understand the implementation process of the vehicle cabin audio playback response time test method obtained by combining this embodiment with the above-mentioned embodiment 1, please refer to Figure 4 , Figure 4 A brief flow chart of a test method for the response time of audio playback in a vehicle cabin is provided. Specifically: the test preparation includes selecting an audio file with a single frequency and fixed loudness for loading the test audio, preparing a decibel detector and a frequency detector for monitoring and recording decibels and frequencies, and frequency and loudness mutations; during the test, video monitoring needs to record the entire test operation process including clicking to play, pausing, and switching songs, etc., wherein it is necessary to select a vehicle system that adapts to a variety of audio playback formats, and perform operations such as playing, switching songs, and pausing from multiple terminals; then the video data is exported for data processing, the exported video data is first subjected to background denoising to improve the test accuracy, and key frames are captured, the click-to-play moment is recorded, the frequency and decibel mutation moment are recorded, and then the response duration is calculated to calculate the time difference of the key frames.

[0081] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the test method for the vehicle cabin audio playback response time of the present application.
