Detailed Implementation

[0015] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the drawings, not the entire structure.

[0016] It's worth noting that when users record videos using mobile devices like smartphones, they sometimes want to achieve directional audio pickup, enhancing sound from certain directions in the recorded video and reducing interference from other directions. This is where the AudioFocus function comes in. AudioFocus primarily works by leveraging the camera's focus information (at 1x magnification) to directionally enhance sound in specific areas, suppressing interference signals from other directions, thus achieving a focused and directional audio pickup effect. AudioFocus high-precision recording utilizes the AudioFocus algorithm even at 1x camera magnification, resulting in better signal focusing.

[0017] However, there is currently no perfect objective method for testing the audio focus effect of the AudioFocus algorithm, and it mainly relies on subjective methods for manual verification.

[0018] In this situation, existing audio focus effect testing techniques often reveal the following shortcomings: 1. Limitations of static testing: Traditional audio focus tests are usually conducted at a fixed angle and in a quiet environment, which cannot reflect the dynamic performance of the device in real-world usage scenarios (such as handheld rotation or bumpy rides in a car).

[0019] 2. Single-dimensional evaluation: Existing methods rely solely on audio signal analysis and lack collaborative testing of multi-dimensional interference factors such as motion state and environmental noise.

[0020] 3. Lack of quantitative indicators: No evaluation system for audio focusing anti-interference capability in dynamic scenarios has been established.

[0021] As an example, in existing technologies, when testing devices, it's often necessary to maintain a certain distance between the speaker and the phone while recording video with the AudioFocus algorithm enabled. The phone is rotated once for each complete audio playback, positioning the speaker at different angles around the phone (e.g., 0°-30°-60°-70°-80°-90°-100°-110°-120°-150°-180°-270°, where 90° is directly in front and 0° is directly to the right of the test device). This verification is extremely complex and conducted in a fixed angle and silent environment, failing to reflect the device's dynamic performance in real-world scenarios (such as handheld rotation or bumpy rides in a car). Finally, the audio amplitude at each angle must be statistically analyzed. Even the amplitude measurements require experienced testers to determine their accuracy, lacking a quantitative indicator.

[0022] Therefore, this disclosure proposes an audio focusing effect testing system, which is widely applicable to acoustic performance evaluation scenarios of devices such as smartphones, smart speakers, and car audio systems. It can accurately, reliably, and automatically test the audio focusing effect by combining dynamic rotation control, environmental noise simulation, and multimodal data analysis.

[0023] Figure 1 This is a schematic diagram of an audio focus effect testing system according to the present disclosure.

[0024] like Figure 1 As shown, the audio focusing effect testing system 1000 includes: a dynamic rotation module 100, an environment simulation module 200, a multimodal data acquisition module 300, and a control and analysis unit 400.

[0025] The dynamic rotation module 100 is used to control the dynamic rotation of the device under test.

[0026] Among them, the environment simulation module 200 is used to play multi-channel noise and a focused sound source for testing the audio focusing effect of the device under test.

[0027] Among them, the multimodal data acquisition module 300 is used to acquire the audio data output by the device under test during the audio focusing effect test, the motion data generated by the dynamic rotation module 100 controlling the dynamic rotation of the device under test, and the multi-channel noise data played by the environmental simulation module 200 during the test of the device under test.

[0028] The control and analysis unit 400 is used to obtain the audio focusing effect test results of the device under test based on audio data, multi-channel noise data and motion data.

[0029] In this disclosure, after the audio focus effect test begins, the dynamic rotation module 100 can control the device under test (such as a mobile phone) to rotate dynamically. Dynamic rotation refers to the object simultaneously undergoing other movements during rotation, such as translation or vibration. Furthermore, the environment simulation module 200 can play at least two types of audio data, including at least multi-channel noise and a focused sound source for testing the audio focus effect of the device under test. The multi-channel noise can be various noises simulating a real environment, such as white noise, traffic noise, or human voice.

[0030] Furthermore, the multimodal data acquisition module 300 can acquire audio data output by the device under test during the audio focus effect test, motion data generated during the dynamic rotation of the device under test controlled by the dynamic rotation module 100, and multi-channel noise data played by the environmental simulation module 200 during the test of the device under test, as well as other multimodal data. Then, the control and analysis unit 400 can evaluate the audio data, multi-channel noise data, and motion data acquired by the multimodal data acquisition module 300 to obtain the audio focus effect test results of the device under test.

[0031] An audio focusing effect testing system according to an embodiment of this disclosure can control the dynamic rotation of the device under test through a dynamic rotation module, play multi-channel noise and a focusing sound source through an environmental simulation module, and collect audio data, motion data, and multi-channel noise data using a multimodal data acquisition module. Finally, a control and analysis unit obtains the audio focusing effect test results of the device under test based on the audio data, multi-channel noise data, and motion data. This embodiment of the disclosure can simulate acoustic interference in real-world scenarios by synchronously combining the motion control of the device under test with environmental noise simulation. Combined with multimodal data acquisition and analysis, it ensures the accuracy and reliability of the audio focusing effect test results, improves the efficiency, automation, and intelligence of the audio focusing effect testing process, reduces manpower input, and provides strong support for subsequent business applications.

[0032] It should be noted that in this disclosure, the control and analysis unit 400 can control the dynamic rotation module 100 and the environmental simulation module 200. The control method is not specifically limited. Optionally, the control and analysis unit 400 can independently control the dynamic rotation module 100 and the environmental simulation module 200; alternatively, the control and analysis unit 400 can synchronously control the dynamic rotation module 100 and the environmental simulation module 200.

[0033] The following example illustrates the control and analysis unit 400's ability to synchronously control the dynamic rotation module 100 and the environmental simulation module 200.

[0034] Figure 2 This is a schematic diagram of another audio focus effect testing system according to the present disclosure.

[0035] like Figure 2 As shown, the control and analysis unit 400 includes: a synchronization control interface 410. The control and analysis unit 400 is also used to: acquire a synchronization control strategy for dynamic rotating multi-channel noise playback, and perform synchronous control on the dynamic rotation module 100 and the environmental simulation module 200 through the synchronization control interface 410 according to the synchronization control strategy.

[0036] For example, when the synchronization control strategy for dynamic rotating multi-channel noise playback is to activate the right-side noise when rotating to 30°, the synchronization control interface 410 will control the dynamic rotation module 100 to rotate to 30°, and when rotating to 30°, control the environmental simulation module 200 to activate the right-side noise.

[0037] It should be noted that, in order to further improve the reliability and intelligence of the audio focusing effect test, this disclosure supports the adjustment of the synchronization control strategy for dynamic rotating multi-channel noise playback.

[0038] As one possible implementation, the control and analysis unit 400 is also used to: in response to detecting an operation that triggers an adjustment of the synchronization control strategy, obtain the adjusted synchronization control strategy, and execute the adjusted synchronization control strategy through the synchronization control interface 410.

[0039] The operation of adjusting the synchronization control strategy can be performed actively by the user or automatically on a regular basis. For example, when the testers and / or the test environment change, the user can actively trigger the operation of adjusting the synchronization control strategy; or, in response to changes in seasons, geographical environment, etc., the audio focus effect test system 1000 can periodically trigger the operation of adjusting the synchronization control strategy at a certain cycle (such as 1 month or 6 months).

[0040] Therefore, the audio focus effect testing system proposed in this disclosure can synchronously control the dynamic rotation module 100 and the environmental simulation module 200 through the synchronous control interface 410 in the control and analysis unit 400, and supports the adjustment of the synchronous control strategy for dynamic rotation multi-channel noise playback, further improving the reliability and intelligence of audio focus effect testing.

[0041] The dynamic rotation module 100 will be further described in detail below through embodiments.

[0042] Figure 3 This is a schematic diagram of another audio focus effect testing system according to the present disclosure.

[0043] like Figure 3 As shown, the dynamic rotation module 100 includes a high-precision electric rotary table 110 capable of supporting the device under test. The high-precision electric rotary table 110 supports full rotation, and both its rotational speed and acceleration are controllable. In other words, the high-precision electric rotary table 110 supports horizontal / vertical axis rotation (0-360°), and its rotational speed (e.g., 0.1-10° / s) and acceleration are programmable.

[0044] In this case, the dynamic rotation module 100 is also used to control the device under test to rotate synchronously with the high-precision electric rotary table 110 via the high-precision electric rotary table 110.

[0045] It should be noted that this disclosure does not limit the specific method by which the high-precision electric rotary table 110 supports the equipment under test; it can be as follows: Figure 4 The device shown can be supported by magnetic attraction, or it can be supported by binding or fixing.

[0046] like Figure 3 As shown, the dynamic rotation module 100 also includes an integrated force sensor 120, used to: acquire installation offset data of the device under test and / or the high-precision electric rotary stage; in response to the installation offset data meeting the calibration conditions, acquire a calibration strategy; and calibrate the installation position of the device under test and / or the high-precision electric rotary stage according to the calibration strategy.

[0047] In this disclosure, an integrated force sensor 120 can detect the installation offset of the device under test and / or a high-precision electric rotary table, and trigger automatic calibration in response to the installation offset data meeting calibration conditions. The calibration conditions can be preset according to actual conditions. For example, the calibration condition can be set to the installation offset data reaching a threshold.

[0048] In this case, the addition of automatic calibration of the device under test and / or the high-precision electric rotary stage can effectively reduce errors in the collected data.

[0049] The environment simulation module 200 will be further described in detail below through examples.

[0050] Figure 5 This is a schematic diagram of another audio focus effect testing system according to the present disclosure.

[0051] like Figure 5 As shown, the environmental simulation module 200 includes a multi-channel noise generator 210 and a noise distribution control system 220; wherein, the noise distribution control system 220 includes a surround speaker array 221, and the environmental simulation module 200 is also used to: control the multi-channel noise generator 210 to generate an adjustable spectrum signal, and control the noise distribution control system 220 to simulate noise sources in at least two directions through the surround speaker array 221.

[0052] In this disclosure, the multi-channel noise generator 210 can generate adjustable spectrum signals such as white noise, traffic noise, and human voice interference; the noise distribution control system 220 can simulate noise sources in different directions (such as left / right channel noise intensity difference ±10dB) through the surround speaker array 221.

[0053] In this case, the addition of a noise distribution control system 220 can acquire noise variables with different noise distributions.

[0054] It should be noted that, in this disclosure, the environment simulation module 200 also includes an audio playback device for playing a focused sound source used to test the audio focusing effect of the device under test. Figure 5 Not shown in the image.

[0055] It should also be noted that this disclosure does not limit the specific settings of the multimodal data acquisition module 300, which can be set according to the actual situation.

[0056] As one possible implementation, a multimodal data acquisition module 300 can be configured, including an audio acquisition unit and a motion sensor. The audio acquisition unit is used to synchronously record the microphone / speaker output signal of the device under test, i.e., audio data, and can also simultaneously acquire audio data played by the environmental simulation module 200. The motion sensor is used to record physical parameters of the device under test, such as rotation angle, angular velocity, and vibration amplitude, i.e., motion data.

[0057] In this case, a motion sensor is added to obtain the distance variable between the mobile phone, the test device, and the target speaker and other environmental simulation modules.

[0058] Furthermore, the control and analysis unit 400 is also used to: obtain the audio focusing characteristics and anti-interference capability evaluation results of the device under test based on audio data, multi-channel noise data and motion data, and obtain the audio focusing effect test results based on the audio focusing characteristics and the environment-motion coupling influence coefficient, wherein the audio focusing effect test results include at least the anti-interference capability evaluation results of the device under test.

[0059] Among them, audio focusing features refer to characteristics such as sound source localization accuracy, signal distortion anti-interference score, and signal-to-noise ratio (SNR) fluctuation range.

[0060] It should be noted that, in this disclosure, the audio focusing effect test results include at least the anti-interference capability assessment results of the device under test (such as anti-interference score, defect type (such as "left channel distortion under high-speed rotation")), and may also include corresponding optimization suggestions (such as adjusting the microphone array spacing). The anti-interference score refers to the weighted result of at least two of the following: Dynamic Signal-to-Noise Ratio (DSNR) data, the rotation angle of the device under test, and the focusing direction deviation. The audio focusing effect test results are obtained based on the audio data and the anti-interference score parameters.

[0061] It should also be noted that this disclosure does not limit the specific method by which the control and analysis unit 400 obtains the audio focusing characteristics and anti-interference capability evaluation results of the device under test based on audio data, multi-channel noise data and motion data, and obtains the audio focusing effect test results based on the audio focusing characteristics and the environment-motion coupling influence coefficient. The method can be set according to the actual situation.

[0062] As one possible implementation, the control and analysis unit 400 can combine data analysis algorithms, establish an anti-interference scoring model, and a sound quality detection model when conducting evaluations.

[0063] Optionally, dynamic signal-to-noise ratio (SNR) data can be calculated based on audio data and multi-channel noise data. Then, based on a pre-established anti-interference scoring model, the dynamic SNR data and motion data such as rotational angular velocity and focus direction deviation are weighted and processed. Finally, based on a pre-trained sound quality detection model, the actual focus effect detection result is obtained. In this case, the audio focus effect test result includes the anti-interference capability assessment result of the device under test and the actual focus effect detection result.

[0064] In this case, quantitative indicators such as dynamic signal-to-noise ratio (DSNR) and environment-motion coupling influence coefficient K are added, which can make up for the shortcomings of traditional single-dimensional evaluation in existing technologies.

[0065] It should be noted that, in order to further improve the reliability and intelligence of the audio focus effect test, this disclosure also supports adjusting the synchronization control strategy for dynamic rotating multi-channel noise playback based on the audio focus effect test results.

[0066] As one possible implementation, the control and analysis unit 400 is also used to: adjust the synchronization control strategy for dynamic rotating multi-channel noise playback in response to the audio focus effect test results meeting the strategy adjustment conditions.

[0067] For example, the control and analysis unit 400 can dynamically adjust the test parameters in the synchronization control strategy for dynamic rotating multi-channel noise playback based on the real-time audio focus effect test results, such as reducing the rotation speed to reproduce the fault scenario.

[0068] In this case, a closed-loop feedback mechanism was added to dynamically adjust the test parameters based on real-time test results, further improving the intelligence level of the audio focusing effect test system.

[0069] It should be noted that, in order to further improve the accuracy and reliability of audio focusing effect testing and reduce errors caused by dynamic rotation and noise playback, this disclosure can also be used to detect based on actual motion data and multi-channel noise data, and adjust the synchronization control strategy for dynamic rotation multi-channel noise playback based on the detection results.

[0070] As one possible implementation, the control and analysis unit 400 is further configured to: acquire expected motion data corresponding to the dynamic rotation module and expected multi-channel noise data corresponding to the environmental simulation module, based on a synchronization control strategy for dynamic rotation multi-channel noise playback. Then, it acquires a first difference between the expected motion data and the motion data, and a second difference between the expected multi-channel noise data and the multi-channel noise data; and adjusts the synchronization control strategy for dynamic rotation multi-channel noise playback in response to the first difference and / or the second difference satisfying the strategy adjustment conditions.

[0071] To more clearly illustrate the testing process of the audio focus effect testing system 1000 disclosed herein, the main testing steps and related effects will be explained below in conjunction with embodiments.

[0072] In this disclosure, considering the difficulty of testing the directional sound pickup effect of the camera's AudioFocus, a listening room or soundproof room can be set up as a quiet testing environment. Furthermore, the AudioFocus function can be automatically activated via the camera interface to record video in landscape mode. Next, the speaker is automatically controlled to play audio at a certain distance from the phone. Then, after each complete audio playback, the motor is controlled to rotate the phone to different positions, and the distance between the speaker and the phone is adjusted mechanically. Finally, the audio data and position data are exported, and the Audition API (Application Programming Interface) is called to perform average RMS amplitude statistics to determine whether it conforms to the positional correspondence in the database.

[0073] Among them, during test preparation, such as Figure 6 As shown, the test environment is a listening room or a soundproof room, kept quiet. Hardware preparation includes a high-precision electric rotary table 110, audio equipment, a multi-channel noise generator 210, a computer, and the device under test, as well as other equipment disclosed herein. Figure 6 Not shown in the image.

[0074] Furthermore, the computer-controlled test machine was set to AudioFocus function, and video was recorded in landscape mode. At the start of recording, the focus direction was initialized by simulating screen taps, for example, focusing on the center of the screen. No further screen taps were used for refocusing during recording. The same audio segment (music signal) was played from a speaker 1.5 m away from the phone for approximately 30 seconds. The sound pressure level at the phone was measured at approximately 60 dBA (SLOW setting). There were no obstructions between the phone microphone and the speaker, and they were at approximately 80 cm height. Both the speaker and the phone were more than 1 m away from the wall, maintaining a constant distance. Video was recorded after each complete audio playback (keeping the recorded audio length and content consistent). A multi-channel noise generator produced white noise.

[0075] Then, use a high-precision electric rotary table to rotate the phone once, so that the speaker is located in different positions on the phone, including all four sides of the phone (e.g., 0°-30°-60°-70°-80°-90°-100°-110°-120°-150°-180°-270°, where 90° is the front of the camera and 0° is the right side of the test machine). At the same time, use an integrated force sensor to detect the installation offset of the device under test and trigger automatic calibration.

[0076] Next, the distance between the phone and the speaker is automatically adjusted. After obtaining the position data, the above operation is repeated. After recording, the audio is collected and physical parameters such as rotation angle, angular velocity, and vibration amplitude are recorded using a motion sensor. Finally, the synchronous control interface is called to dynamically adjust the rotation parameters and noise parameters. Data analysis algorithms are used to extract audio focusing features (sound source positioning accuracy, signal distortion (THD), signal-to-noise ratio fluctuation range), calculate the environment-motion coupling influence coefficient, and generate a test report (outputting anti-interference score, defect type (such as "left channel distortion under high-speed rotation") and optimization suggestions (such as adjusting the microphone array spacing)).

[0077] In summary, considering the lack of objective acceptance standards for AudioFocus and the time-consuming, labor-intensive, and potentially inaccurate nature of manual subjective acceptance, this disclosure proposes an automated testing system for the directional audio pickup effect of AudioFocus in cameras. This system can automatically complete the testing of relevant audio functions, improving testing efficiency and accuracy while reducing manpower. Specifically, the audio focusing effect testing system proposed in this disclosure combines dynamic rotation and environmental noise synchronization control with multimodal data analysis to solve the performance quantification problem of AudioFocus in complex scenarios. It provides an accurate automated testing solution for AudioFocus directional audio pickup effect detection. Specifically, while simulating a noisy environment, it combines a dynamic rotation control system based on sound source localization feedback to extract audio focusing features (sound source localization accuracy, signal distortion (THD), signal-to-noise ratio fluctuation range), calculate the environment-motion coupling influence coefficient, and dynamically adjust test parameters based on real-time test results (e.g., reducing rotation speed to reproduce fault scenarios).

[0078] Figure 7 This is a flowchart illustrating an audio focus effect testing method provided in an embodiment of the present disclosure. The audio focus effect testing method is applicable to an audio focus effect testing system 1000, which includes: a dynamic rotation module 100, an environment simulation module 200, a multimodal data acquisition module 300, and a control and analysis unit 400.

[0079] As one possible implementation, such as Figure 7 As shown, the specific steps include: S701, Control the device under test to rotate dynamically.

[0080] S702, plays multi-channel noise and a focused sound source for testing the audio focusing effect of the device under test.

[0081] S703: Collects audio data output by the device under test during audio focus effect testing, motion data generated during dynamic rotation of the device under test controlled by the dynamic rotation module, and multi-channel noise data played by the environment simulation module during the testing of the device under test.

[0082] S704. Perform multimodal evaluation processing on audio data, multichannel noise data, and motion data to obtain the audio focusing effect test results of the device under test.

[0083] In this disclosure, after the audio focus effect test begins, the dynamic rotation module 100 can control the device under test (such as a mobile phone) to rotate dynamically. Dynamic rotation refers to the object simultaneously undergoing other movements during rotation, such as translation or vibration. Furthermore, the environment simulation module 200 can play at least two types of audio data, including at least multi-channel noise and a focused sound source for testing the audio focus effect of the device under test. The multi-channel noise can be various noises simulating a real environment, such as white noise, traffic noise, or human voice.

[0084] Furthermore, the multimodal data acquisition module 300 can acquire audio data output by the device under test during the audio focus effect test, motion data generated during the dynamic rotation of the device under test controlled by the dynamic rotation module 100, and multi-channel noise data played by the environmental simulation module 200 during the test of the device under test, as well as other multimodal data. Then, the control and analysis unit 400 can perform multimodal evaluation processing based on the audio data, multi-channel noise data, and motion data acquired by the multimodal data acquisition module 300 to obtain the audio focus effect test results of the device under test.

[0085] According to an embodiment of this disclosure, an audio focus effect testing method can be implemented by controlling the device under test to dynamically rotate, playing multi-channel noise, and using a focused sound source for testing the audio focus effect of the device under test. Then, audio data output by the device under test during the audio focus effect test, motion data generated during the dynamic rotation of the device under test controlled by the dynamic rotation module, and multi-channel noise data played by the environmental simulation module during the test are collected. Based on the audio data, multi-channel noise data, and motion data, the audio focus effect test result of the device under test is obtained. This embodiment of the disclosure can simulate acoustic interference in real-world scenarios by synchronously combining the motion control of the device under test with environmental noise simulation. Combined with multi-modal data acquisition and analysis, it ensures the accuracy and reliability of the audio focus effect test results, improves the efficiency, automation, and intelligence of the audio focus effect testing process, reduces manpower input, and provides strong support for subsequent business applications.
