[0030] To make the objectives, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be described below in a clear and complete manner with reference to the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only some of the embodiments of the present disclosure but not all the embodiments. Based on the embodiments in the present disclosure, any other embodiments obtained by those skilled in the art without creative work fall within the scope of the present disclosure.

[0031] It can be understood that, before using the technical solutions disclosed in the embodiments of the present disclosure, the type, use range, use scenario and the like of the personal information involved in the present disclosure should be informed to the user and the authorization of the user should be obtained through appropriate means according to relevant laws and regulations.

[0032] For example, in response to receiving an active request of a user, prompt information is sent to the user to explicitly prompt the user that the operation requested to be performed will need to obtain and use the personal information of the user. Thus, the user can autonomously select whether to provide the personal information to the software or hardware such as an electronic device, an application program, a server or a storage medium performing the operation of the technical solutions of the present disclosure according to the prompt information.

[0033] As an optional but non-limiting implementation manner, in response to receiving an active request of a user, the manner of sending prompt information to the user may, for example, be a pop-up window manner, and the prompt information may, for example, be presented in the form of text in the pop-up window. In addition, the pop-up window may, for example, carry a selection control for the user to select “agree” or “disagree” to provide the personal information to the electronic device.

[0034] It can be understood that the above notification and obtaining of user authorization process is only illustrative, and does not limit the implementation manners of the present disclosure, and other manners meeting relevant laws and regulations can also be applied to the implementation manners of the present disclosure.

[0035] It can be understood that the data (including but not limited to the data itself, the acquisition or use of the data) involved in the present technical solution should comply with the requirements of relevant laws and regulations and relevant provisions.

[0036] In the related art, the synchronization test of the audio of the user and the background audio is performed by playing the background audio at the recording end and outputting the audio by a real person, recording the background audio and the audio output by the real person and sending them to the playing end for playing, and a test personnel analyzes the synchronization degree of the audio heard according to his own experience at the playing end to obtain a synchronization analysis result. However, this process needs to rely on a real person to output the audio, and the synchronization analysis result is obtained according to the experience of the test personnel, so that the test result is relatively subjective and cannot be reproduced.

[0037] Taking a chorus scene as an example, in addition to some functional effects and sound quality effects such as the synchronization of music and lyrics progress, ear return sound quality, device switching experience, and volume balance and the like, which affect the user experience in the chorus scene, the most important one is the synchronization of the voice and the accompaniment, that is, the voice accompaniment synchronization. For the audience end, the effect of the multi-path voice and the accompaniment progress expected to be heard is that the voices of all the singers can be synchronized with the accompaniment, and the offline chorus is restored as much as possible. However, due to the inconsistent delay introduced by the audio processing link when processing the voice and the accompaniment, the voice and the accompaniment cannot be accurately synchronized during mixing, so in the actual scene, the singers sing along with the accompaniment, but the audience hears that the voice of the singer is out of sync with the accompaniment, that is, the voice is ahead of the accompaniment or the voice lags behind the accompaniment. For this scene, the voice accompaniment synchronization test in the related art is implemented based on active testing, that is, multiple people act as singers, sing a song online with different devices, and the audience end subjectively tests the synchronization of the voice of each singer and the accompaniment.

[0038] However, in the above scheme, the chorus voice accompaniment synchronization test is a subjective test of real singing by real people, which is greatly affected by the singing level of the singers themselves, and the hearing level of the sound listening test personnel is required to be high, so that the test result is greatly affected by the subjectivity.

[0039] Therefore, based on this, the embodiment of the present disclosure provides an audio test method, which plays test audio for simulating the audio output by a user, records corresponding first recording audio for each recording end; then plays the background audio and the test audio played by each recording end at the playing end to simulate the audio heard by the user at the playing end, and records the audio played at the playing end to obtain second recording audio. The first recording audio and the second recording audio are subjected to audio detection to obtain the starting time of the background audio of each recording end and the detection time of the test audio of each recording end in the second recording audio, and through time comparison and analysis, the synchronization test result of the second recording audio can be obtained. The synchronization test result includes but is not limited to the synchronization of the test audio of each recording end and the background audio, the background audio delay of each recording end, and the synchronization between each recording end, and the like.

[0040] This audio testing method simulates user audio by playing test audio, eliminating the use of actual user audio and thus avoiding errors caused by subjective factors leading to discrepancies between user audio and background audio. Furthermore, this method can perform device coverage testing, simultaneously testing the audio synchronization of multiple devices.

[0041] If this audio testing method is applied to a choral setting where there is no live singer, the test audio is played using a playback device to replace the singer's performance, thus avoiding errors caused by the live singer's performance not being in sync with the accompaniment.

[0042] This disclosure also provides an audio testing system, such as... Figure 1 As shown, this system can simultaneously test n recording devices. Each recording device includes a first playback device, a first recording device, and a third playback device. The first playback device plays background audio, and the third playback device plays the corresponding test audio from each recording device. The test audio corresponds one-to-one with the recording device. The first recording device records both the background audio and the test audio to obtain the first recorded audio. Specifically, the test audio played by the third playback device can be single-frequency tones of different frequencies, or it can be replaced by other different tapping sounds or signals of different lengths. The specific form of the test audio is not limited here and can be set according to actual needs.

[0043] The first recording device is used to record audio played by the first playback device and the third playback device to obtain a first recorded audio. The first recorded audio includes background audio and test audio from the recording device. The playback device is used to simulate audio output by n users based on the same background audio, and includes a second playback device and a second recording device. The second playback device is used to play the background audio and the test audio played by the n recording devices. The test audio played by the recording devices is sent to the recording device, played by the second playback device of the playback device, and thus recorded by the second recording device to obtain the second recorded audio.

[0044] During testing, background audio is played simultaneously on the first playback device of all recording terminals and the second playback device of all playback terminals. Recording begins simultaneously on the first recording device of all recording terminals and the second recording device of the playback terminals. The recording start time can be at the same time as the background audio is playing, or after the background audio has been playing for a period of time, etc. There are no restrictions on the timing of the recording; it can be set according to the actual needs.

[0045] Electronic devices are used to control the devices at each recording end and the devices at the playback end. For example, they can control the playback of background audio at the recording end and the playback end, control the playback of test audio at the recording end, and control the recording of the first recording device and the second recording device, etc.

[0046] In the test process, in order to avoid the influence of other audio on the test results, each recording end and the playing end need to be tested in a quiet environment. For example, the recording end is set in an anechoic box, or each recording end is set in an independent test room, etc. The first playing device to the third playing device can adopt a manual mouth or other devices with audio playing function, and the first recording device and the second recording device can adopt a standard microphone or other devices with audio recording function. The electronic device can adopt a sound card, or can be replaced by other devices that can control multiple recording or playing devices to record or play simultaneously.

[0047] In some optional embodiments, taking the synchronous test in a chorus scene as an example, Figure 2 A specific application example of the audio test system is shown. In the recording studio, four anechoic boxes are used to test the synchronization performance of four singing devices, respectively. In each anechoic box, a singing device, a player and a recorder are arranged. Among them, the singing device 1 to the singing device 4 correspond to the first playing device in Figure 1 , the player 1 to the player 4 correspond to the third playing device in Figure 1 , the recorder 1 to the recorder 4 correspond to the first recording device in Figure 1 ; for the playing end, the audience device corresponds to the second playing device in Figure 1 , and the audience end recording device corresponds to the second recording device in Figure 1 .

[0048] Specifically, four independent and mutually independent anechoic boxes are placed in the same recording studio, and each anechoic box is placed with a singing device, a recorder for audio recording, and a player for playing test audio to act as a singer. The playing & recording triggering device corresponds to the electronic device in Figure 1 , generally adopts a sound card, and is used for the player in each anechoic box to play sound. The recording triggering device is used for the recorder in each anechoic box to record sound synchronously, and the singing device in the anechoic box sends the test audio played by the player to the audience end device for playing. Correspondingly, the audience end recorder can collect the background audio and the test audio played by the player of each recording end.

[0049] In a multi-person chorus scenario, user A selects a song as accompaniment in a chorus application, allowing users B, C, and D to join the chorus. Users A through D sing the song together, sometimes in turn, sometimes in unison, while other listeners hear the multi-dimensional chorus effect. Based on this chorus method, test scenarios include real-time chorus-round and real-time chorus-unison. In round, users A through D sing in turn without overlapping; in unison, users A through D sing together with overlapping vocals.

[0050] The real-time chorus scenario is divided into round singing and chorus singing. In the round singing scenario, the player is triggered to play audio in turn according to the number, and at the same time, the recorder with the corresponding number and the audience recorder are triggered to record audio, thereby obtaining the first recorded audio from each singer and the second recorded audio from the audience. The first and second recorded audio are used to obtain the round singing related indicators. In the chorus singing scenario, all players are triggered to play audio simultaneously, and the recorder with the corresponding number and the audience recorder are triggered to record audio, so that the first and second recorded audio are used to obtain the chorus-related indicators.

[0051] by Figure 2 For example, singing devices 1 through 4 play accompaniment simultaneously. During a round, players 1 through 4 are triggered in turn to play test audio. Recorders 1 through 4, as well as the audience-end recorder, are also triggered to record audio. During a chorus, players 1 through 4 play their corresponding test audio simultaneously, and recorders 1 through 4 record audio simultaneously. During a round, the players play the test audio sequentially, with only one person singing at a time; during a chorus, all players play the test audio simultaneously, and all singers sing together. Regardless of whether it's a round or a chorus, the corresponding numbered recorders are triggered simultaneously. Combining the audio testing method provided in this embodiment, the vocal accompaniment synchronization degree of each singer can be calculated in both round and chorus scenarios. Furthermore, in the chorus scenario, the synchronization degree of all singers' local players and the alignment degree of all singers' voices heard by the audience can be output simultaneously.

[0052] According to an embodiment of this disclosure, an audio testing method embodiment is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0053] This embodiment provides an audio testing method that can be used in electronic devices, such as computers, mobile terminals, etc. Figure 3 This is a flowchart of an audio testing method according to an embodiment of the present disclosure, such as... Figure 3As shown, the flow includes the following steps:

[0054] In step S301, the first recording audio of each recording terminal and the second recording audio of the playing terminal are acquired.

[0055] The first recording audio and the second recording audio both include the background audio played simultaneously, and the first recording audio further includes the test audio corresponding to the recording terminal and played by the playing device of the recording terminal. The second recording audio is the playing audio of the playing terminal, which includes the background audio and the test audio played by all the playing terminals.

[0056] It should be noted that the number of recording terminals in the embodiment can be one, two or more, which is set according to actual test requirements, and is not limited herein. The first recording audio corresponds to the recording terminal, and includes the background audio and the test audio played by the playing device of the recording terminal. As shown above, all the playing devices of the recording terminals and the playing terminal play the background audio simultaneously. Since each playing device can have different playing delays, the starting time of the background audio recorded by the recording device of each recording terminal has a delay. For all the recording devices, the starting time of recording can be before, at the same time or after playing the background audio, which is not limited.

[0057] The first recording audio further includes the test audio corresponding to the recording terminal, which is used to simulate the user audio. For example, the test audio is a single-frequency audio with different frequencies. In combination with the above description of the playing terminal, the test audio played by the third playing device can be received by the first playing device and sent to the second playing device. Accordingly, the audio played by the second playing device includes the background audio and the test audio of each recording terminal. Figure 1 As shown, all the first playing devices and the second playing device play the background audio simultaneously, the third playing device plays the test audio, and all the first recording devices and the second recording device start recording simultaneously. Since the test audio played by the third playing device can be received by the first playing device and sent to the second playing device, accordingly, the audio played by the second playing device includes the background audio and the test audio of each recording terminal. The playing terminal records the audio played by the second playing device to obtain the second recording audio.

[0058] In step S302, the audio of each first recording audio is detected to obtain the starting time of the background audio in each first recording audio.

[0059] If there are multiple recording ends, multiple first recorded audios corresponding to the recording ends are obtained. The processing of the multiple first recorded audios can be parallel processing, or sequential processing, etc. The audio detection is performed on the first recorded audio to obtain the starting time of the background audio. The detection manner can be that the feature of the background audio is obtained, the feature of the first recorded audio is extracted, and the two features are compared to obtain the starting time of the background audio. Alternatively, the background audio and the first recorded audio can be converted into the frequency domain, and alignment processing is performed in the frequency domain to obtain the starting time of the background audio.

[0060] As shown above, although all the first playing devices are playing the background audio at the same time, the starting time of the background audio recorded by each first recording device is different due to the different playing delays of the first recording devices. Through the above processing manner, the starting time of the background audio in each first recorded audio can be obtained. If the recording end 1 to the recording end n are involved in the test manner, the first recorded audio 1 to the first recorded audio n are obtained accordingly, and the starting time of the background audio in the first recorded audio 1 to the first recorded audio n is t1 to tn respectively.

[0061] In step S303, audio detection is performed on the second recorded audio to obtain the starting time of the background audio in the second recorded audio and the detection time of each test audio.

[0062] The second recorded audio includes the background audio and the test audio of each recording end. The detection manner of the background audio is similar to that of step S302, and the starting time t of the background audio in the second recorded audio is obtained. The test audio is one-to-one corresponding to the recording end, and accordingly, different test audios have different features. Based on this, each test audio is detected from the second recorded audio through audio feature detection, so that the detection time of each test audio can be obtained. The detection time of the test audio is the time when the playing end plays the test audio, which can also be regarded as the starting time of the test audio in the second recorded audio. For the convenience of description, the detection time of the test audio of the recording end 1 to the recording end n in the second recorded audio is marked as T1 to Tn.

[0063] Due to the different collection delays of each first playing device, the starting time of the test audio received by the playing end and the background audio are not aligned. Alternatively, in the scenario where the test audio is played at the same time, due to the different collection delays of each first playing device, the test audio of each recording end received by the playing end is not aligned, and the delay introduced by the audio processing link when processing the test audio and the background audio is inconsistent, which can cause the test audio and the background audio to be not accurately aligned when mixing. Therefore, in the second recorded audio, each test audio has a corresponding detection time.

[0064] It should be noted that the implementation of the audio detection is not limited here, and can be set according to actual needs.

[0065] In step S304, the starting time of the background audio in the second recorded audio and the detection time of each test audio are compared with the starting time of the background audio in each first recorded audio to determine the synchronization test result of the second recorded audio.

[0066] If there is only one recording end, the starting time of the background audio in the first recorded audio can be compared with the starting time of the background audio in the second recorded audio to obtain the delay of the starting time of the background audio. The time when the test audio is played by the recording end can be compared with the detection time of the test audio in the second recorded audio to obtain the delay of the test audio. The difference between the detection time of the test audio in the second recorded audio and the playing time of the test audio, and the difference between the delay of the starting time of the background audio, are used to obtain the sound partner asynchronization degree, which is used to represent the asynchronization degree of the test audio and the background audio.

[0067] If there are multiple recording ends, the synchronization of the test audio between each recording end and the alignment of all test audios in the actual scene can be calculated. Of course, in the case of multiple recording ends, the synchronization of a single recording end can also be tested. The specific determination of the test index in the synchronization test result of the second recorded audio is set according to actual needs, and is not limited here.

[0068] The audio test method provided in the embodiment can ensure the objectivity of the test result for each recording end, because the same background audio and the test audio corresponding to the recording end are played, and the test audio is automatically played rather than manually output. Meanwhile, the first recorded audio includes the background audio and the test audio corresponding to the recording end, and the second recorded audio includes the same background audio and the test audio played by the playing device of all recording ends. The playing of the audio by the playing end is simulated through the second recorded audio, and the starting time of the background audio in each first recorded audio, the starting time of the background audio in the second recorded audio, and the detection time of each test audio are obtained through the audio detection of the first recorded audio and the second recorded audio. Therefore, the synchronization test result corresponding to each recording end can be represented in the second recorded audio, the entire test process is automatically implemented, the audio does not need to be manually output, the test result is not affected by subjective factors, and the accuracy of the synchronization test result is ensured in an objective manner.

[0069] In the embodiment, an audio test method is provided, which can be used in electronic devices such as computers, mobile terminals, and the like. Figure 4 The flowchart of the audio test method according to the embodiment of the present disclosure is shown in FIG. 1, which includes the following steps: Figure 4 ​

[0070] Step S401, obtaining the first recording audio of each recording end and the second recording audio of the playing end.

[0071] The first recording audio and the second recording audio both include background audio played simultaneously, the first recording audio further includes test audio corresponding to the recording end one by one and played by the playing device of the recording end, and the second recording audio is the playing audio of the playing end, which includes the background audio and the test audio played by all the playing ends. For details, please refer to Figure 3 Step S301 of the embodiment shown, which will not be repeated here.

[0072] Step S402, audio detection is performed on each first recording audio to obtain the starting time of the background audio in each first recording audio. For details, please refer to Figure 3 Step S302 of the embodiment shown, which will not be repeated here.

[0073] Step S403, audio detection is performed on the second recording audio to obtain the starting time of the background audio in the second recording audio and the detection time of each test audio. For details, please refer to Figure 3 Step S303 of the embodiment shown, which will not be repeated here.

[0074] Step S404, based on the starting time of the background audio in the second recording audio and the detection time of each test audio, and the starting time of the background audio in each first recording audio, the synchronization test result of the second recording audio is determined.

[0075] Specifically, the above step S404 includes:

[0076] Step S4041, obtaining the starting time of the background audio in the first recording audio of the reference recording end to obtain a reference starting time.

[0077] In the above step S402, the starting time of the background audio in each first recording audio is obtained, one of the recording ends is selected as a reference recording end, and the starting time of the background audio in the first recording audio of the reference recording end is taken as a reference starting time. For example, the first recording end is taken as the reference recording end. Of course, the reference recording end is set according to actual needs, which is not limited here.

[0078] In the chorus scene, different recording ends correspond to different singers. If there are n singers, there are n recording ends, and each recording end obtains the first recording audio. The background audio in the first recording audio is the accompaniment recorded.

[0079] For example, in Figure 5The n singers correspond to the accompaniment shown in the middle, which is recorded. From the above description, it can be known that due to the playing delay of the playing device of each recording end, the recorded accompaniment has a delay. In Figure 5 In the middle, the starting time of the recorded accompaniment corresponding to the singer 1-singer n is 0, t1-t n. Among them, the recording end of the singer 1 is determined as the reference recording end, and correspondingly, the starting time of the background audio thereof is determined as the 0 time.

[0080] Step S4042, based on the difference between the starting time of the background audio in the second recording audio and the reference starting time, the starting delay of the background audio in the second recording audio is determined.

[0081] The starting time t of the background audio in the second recording audio is obtained by the above step S403, which is used to represent the starting time of the background audio heard at the playing end. Among them, the difference between the starting time of the background audio in the second recording audio and the reference starting time is determined as the starting delay of the background audio in the second recording audio. If the reference starting time is determined as 0 time, the starting delay of the background audio in the second recording audio is t.

[0082] Step S4043, the time of simultaneously playing the test audio is obtained, and the test audio playing time is obtained.

[0083] The time of simultaneously playing the test audio is recorded as T, for example, after playing the background audio for 5s, the test audio is played, and 5s is determined as the test audio playing time. Among them, the playing time of the test audio is set according to the actual demand, which is not limited here. In the test process, the test audio of each recording end can be played only once, or played multiple times according to the demand, and the interval of each time of playing the test audio can be the same or different, etc.

[0084] Step S4044, based on the detection time of each test audio in the second recording audio, the starting delay of the background audio in the second recording audio and the starting time of the background audio in each first recording audio, the synchronization test result of the second recording audio is determined.

[0085] The synchronization test result includes the different step degree of the test audio and the background audio of each recording end heard at the playing end, which is called the sound accompaniment different step degree, recorded as list A. In the chorus scene, it refers to the different step degree of the voice and the accompaniment of each singer heard at the audience end when multiple people start singing at the same time.

[0086] The synchronization test result can also include the playing device different step degree, which is used to represent the delay difference between the background audio recorded by different recording ends, recorded as list B. In the chorus scene, it refers to the delay difference between the local playing accompaniment of multiple people.

[0087] The synchronization test result can further include alignment of all the test audio heard by the playback end from the recording end, denoted as list C. In the chorus scenario, it refers to the alignment of all the singer voices heard by the audience end, which means that all the singers start singing at the same time, and the time difference between the starting time of each singer received by the audience end and the starting time of the reference singer.

[0088] The synchronization test result can further include alignment of all the test audio heard by the playback end from the recording end, denoted as list C. In the chorus scenario, it refers to the alignment of all the singer voices heard by the audience end, which means that all the singers start singing at the same time, and the time difference between the starting time of each singer received by the audience end and the starting time of the reference singer.

[0089] The synchronization test result can further include the difference between the maximum value and the minimum value of the above-mentioned list D, denoted as delay_align. In the chorus scenario, the actual alignment of the audience end is defined as the maximum relative time difference of all the singers received by the audience end, denoted as alignment (i.e., the time difference between the earliest singing and the latest singing heard by the audience end).

[0090] It should be noted that, taking the chorus scenario as an example, if the voice-accompaniment synchronization degree calculation result is positive, it means that the accompaniment leads the voice; if it is negative, it means that the voice leads the accompaniment; if the alignment calculation result is positive, it means that the current singer voice lags behind the reference singer voice; if it is negative, it means that the current singer voice leads the reference singer voice.

[0091] In some optional embodiments, the above step S4044 includes:

[0092] Step a1, obtaining the test audio time difference corresponding to each recording end based on the difference between the detection time of the test audio corresponding to the recording end in the second recording audio and the playback time of the test audio.

[0093] Step a2, obtaining the background audio time difference corresponding to each recording end based on the difference between the starting time of the background audio in each first recording audio and the starting time of the background audio.

[0094] Step a3, for each recording terminal, based on the difference between the test audio time difference and the background audio time difference, obtain the different synchronization degree of the test audio and the background audio, and the synchronization test result includes the background audio time difference corresponding to each recording terminal and the different synchronization degree of the test audio and the background audio.

[0095] The detection time of the test audio corresponding to the recording terminal in the second recording audio is represented as T1-Tn when the test audio playing time T is played, and the test audio time difference corresponding to the recording terminal 1-recording terminal n is represented as [T1-T, T2-T, …, Tn-T].

[0096] If the reference starting time is determined as 0 time, the starting delay of the background audio in the second recording audio is t, and the starting time of the background audio in each first recording audio is represented as 0, t2-tn, that is, list B=[0, t2, …, tn]. Based on this, the background audio time difference corresponding to each recording terminal is represented as [t, t-t2, t-t3, …, t-tn].

[0097] For each recording terminal, the difference between the test audio time difference and the background audio time difference in the second recording audio obtains the different synchronization degree of the test audio and the background audio list A, which is represented as list A=[(T1-T)-t, (T2-T)-(t-t2), …, (Tn-T)-(t-tn)]. Wherein, the elements of list A correspond to the recording terminals one by one, the first element corresponds to the first recording terminal, the second element corresponds to the second recording terminal, and so on, the nth element corresponds to the nth recording terminal.

[0098] Due to the influence of the playing performance of each playing device, it will cause playing delay. Based on this, through the starting time of the background audio in the first recording audio of each recording terminal, the corresponding background audio time difference is obtained, and the synchronization analysis result of the playing device can be obtained. At the same time, by using the test audio time difference and the background audio time difference, the sound accompaniment synchronization degree of each recording terminal can be obtained.

[0099] In some optional embodiments, the above step S4044 includes:

[0100] Step b1, obtaining the detection time of the test audio corresponding to the reference recording terminal in the second recording audio, and obtaining the reference starting time of the test audio.

[0101] Step b2, based on the difference between the detection time of each test audio in the second recording audio and the reference starting time of the test audio, obtain the test audio first synchronization test result corresponding to each recording terminal.

[0102] The detection time of the test audio corresponding to the reference recording end in the second recording audio is represented as T1-Tn. If the first recording end is recorded as the reference recording end, the reference starting time of the test audio is T1. By calculating the difference between the detection time of each test audio in the second recording audio and the reference starting time of the test audio, the first synchronization test result of the test audio corresponding to each recording end is obtained, that is, list C, list C = [0, T2-T1, …, Tn-T1]. The elements in the list C correspond to the recording ends one by one.

[0103] The first synchronization test result of the test audio is used to represent the delay difference of the test audio of the remaining recording end relative to the reference recording end, and is used to represent the synchronization of the test audio of each recording end.

[0104] In some optional embodiments, the step S4044 comprises: obtaining the second synchronization test result of the test audio corresponding to each recording end based on the sum of the starting time of the background audio in each first recording audio and the first synchronization test result of the test audio corresponding to each recording end.

[0105] The starting time of the background audio in each first recording audio is list B = [0, t2, …, tn], and the first synchronization result of the test audio corresponding to each test end is list C = [0, T2-T1, …, Tn-T1]. The sum of the two is used to represent the second synchronization test result of the test audio corresponding to each recording end: list D = list B + list C = [0, T2-T1+t2, …, Tn-T1+tn].

[0106] In actual scenarios, due to different device playback delays of each participant, the local playback of the background audio is not synchronized, and each participant performs card shooting according to the local playback of the background audio. The second synchronization test result of the test audio can represent the alignment degree of the sound of all participants that the playback end can hear in the actual scenario.

[0107] In some optional embodiments, the step S4044 comprises:

[0108] Step c1, comparing the size of the second synchronization test result of the test audio corresponding to each recording end, obtaining the maximum value and the minimum value of the second synchronization test result of the test audio.

[0109] Step c2, obtaining the maximum relative delay difference of the test audio based on the difference between the maximum value and the minimum value.

[0110] Compare the magnitudes of the second synchronization test results for each test audio to obtain the maximum value (max(list D)) and minimum value (min(list D)) of the second synchronization test results for the test audio. By calculating the difference between the maximum and minimum values, the maximum relative delay difference (delay_align) of the test audio is obtained, expressed as: delay_align = max(list D) - min(list D).

[0111] By comparing the maximum and minimum values ​​of the second synchronization test results of the test audio, the difference between the two values ​​is used to represent the time difference between the earliest and latest sounds that can be heard at the playback end.

[0112] The audio testing method provided in this embodiment determines a reference recording end among all recording ends and uses the start time of the background audio in the first recorded audio as the reference start time, thereby obtaining the start delay of the background audio corresponding to each recording end; then, it obtains the time when the test audio is played simultaneously and uses it as the reference for the test audio. After obtaining the reference start time of the background audio and the reference of the test audio, it performs synchronous test analysis on the second recorded audio based on this, and can obtain accurate synchronous test results.

[0113] This embodiment provides an audio testing method that can be used in electronic devices, such as computers, mobile terminals, etc. Figure 6 This is a flowchart of an audio testing method according to an embodiment of the present disclosure, such as... Figure 6 As shown, the process includes the following steps:

[0114] Step S601: Obtain the first recorded audio from each recording end and the second recorded audio from the playback end.

[0115] The first and second recorded audios both include background audio played simultaneously. The first recorded audio also includes test audio that corresponds one-to-one with the recording end and is played by the playback device of the recording end. The second recorded audio is the playback audio of the playback end, which includes background audio and all test audio played by the playback end.

[0116] Specifically, step S601 includes:

[0117] Step S6011: Control the first playback device of each recording end and the second playback device of each playback end to play background audio simultaneously.

[0118] like Figure 1 As shown, the first playback device in each recording end and the second playback device in the playback end play background audio simultaneously. For example, playback commands are sent to the first playback device and the second playback device at the same time to trigger the simultaneous playback of background audio.

[0119] Step S6012, control the first recording device of each recording end and the second recording device of the playing end to start recording at the same time.

[0120] The starting recording time of the first recording device and the second recording device can be before, at the same time or after playing the background audio, which is not limited herein. For example, the recording instruction is issued to the first recording device and the second recording device at the same time to trigger the simultaneous recording of the audio.

[0121] Step S6013, control the third playing device of each recording end to play the corresponding test audio at the same time, and the test audio played by all the third playing devices is sent to the second playing device for playing.

[0122] Each test audio is played at the same time. Therefore, the test audio playing instruction is issued to each third playing device at the same time to trigger the simultaneous playing of the test audio. The test audio played by the third playing device is collected by the first playing device and sent to the second playing device for playing. At this time, the audio played by the second playing device includes the background audio and the test audio played by each recording end.

[0123] Step S6014, obtain the recording result of the first recording device of each recording end to obtain the first recording audio of each recording end.

[0124] Step S6015, obtain the recording result of the second recording device to obtain the second recording audio.

[0125] The first recording device records the audio of the recording end to obtain the first recording audio, and the first recording audio is one-to-one corresponding to the recording end. The second recording device records the audio of the playing end to obtain the second recording audio.

[0126] Step S602, perform audio detection on each first recording audio to obtain the starting time of the background audio in each first recording audio. For details, please refer to step S302 of the embodiment shown in Figure 1 The step S302 of the embodiment shown in

[0127] Step S603, perform audio detection on the second recording audio to obtain the starting time of the background audio in the second recording audio and the detection time of each test audio. For details, please refer to step S303 of the embodiment shown in Figure 1 The step S303 of the embodiment shown in

[0128] Step S604, based on the starting time of the background audio in the second recording audio and the detection time of each test audio, and the starting time of the background audio in each first recording audio, determine the synchronization test result of the second recording audio. For details, please refer to step S404 of the embodiment shown in Figure 4 The step S404 of the embodiment shown in

[0129] The audio test method provided by the embodiment can automatically control the background audio, play the test audio and record the recording device without human intervention, that is, the playing device and the recording device are used to perform objective test, so that the method can efficiently obtain the synchronous test result and has strong reproducibility.

[0130] As a specific application embodiment of the present disclosure, the audio test method is combined with Figure 2 As shown in the figure, in the chorus scene, four sound-absorbing boxes are used to represent four recording ends, the players in each sound-absorbing box are used to represent each singer, and the singing device is used to play the accompaniment and collect the single-frequency sound played by the player and then send it to the audience device. Correspondingly, the audio played by the audience device includes the accompaniment and the single-frequency sound played by each player. Corresponding to the four recording ends, there are four test audios, respectively, and different frequencies, same energy and same length of single-frequency sound are generated at the fixed positions of the test audios, which are used to simulate the sound of different singers. For example, single-frequency sound with a frequency of 0.25KHz, 0.5KHz, 0.75KHz and 1KHz and a length of 100ms is generated at the 6th second and the 7th second, respectively, so that the test audio corresponding to each singer can be obtained. The frequency and length of the single-frequency sound in the test audio are set according to actual needs, and are not limited herein. The recorder 1 to the recorder 4 are used to record four first recording audios, and the audience end recorder is used to record a second recording audio. After obtaining the first recording audio and the second recording audio, the audio test method introduced above is used for processing to obtain the synchronous test result of the second recording audio.

[0131] The above-mentioned indexes list A, list B, list C and list D can describe the alignment effect of the multi-channel voice and accompaniment heard by the audience in the real-time chorus scene, the synchronization degree of all local players of the singers, and the synchronization degree of the sound heard by the audience in the valley. The calculation result of list D can also be calculated by list A, list A measures the delay difference between the voice of each singer and the accompaniment heard by the audience, and list D measures the delay difference between the voices of all singers heard by the audience. For list A and list D, the difference between adjacent elements is equal, so list D can be calculated by list A.
