Description

Technical Field

[0001] The embodiments of the present application relate to the field of audio processing technology, and in particular, to a method, device, storage medium and equipment for identifying an audio data encapsulation format. Background Art

[0002] The encoding of audio data is used in many fields, such as the transmission of telephone voice, the transmission of video and audio, etc. In the industry, there is a more standardized encoding method, namely the G711 audio data encoding format. This encoding format has the advantages of high sound clarity and high voice naturalness. In fact, G711 encoding is also divided into G711A and G711U. Although both encodings belong to G711, the encoding strategies and methods are completely different, the application areas are also different, and the effects of emphasis are also different. For example, the G711A audio data encoding format is obtained by calculating specific symbols and samples, and needs to be specially designed to facilitate the rapid calculation of digital devices. The G711U encoding format is obtained by looking up the table and adding the basic value to the average offset value, and the encoding speed is faster.

[0003] During the audio data transmission process, once the field indicating the encoding format is lost, it is difficult to quickly determine the encoding format. There is no effective solution to this problem in general technology. One can only select an encoding format for decoding based on guesswork, and this method is not very accurate. Once the encoding format is selected incorrectly, the audio format cannot be decoded correctly, resulting in a noisy and chaotic sound effect. Summary of the invention

[0021] The present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only the parts related to the present application, rather than all structures, are shown in the accompanying drawings.

[0022] It should be mentioned before discussing the exemplary embodiments in more detail that some exemplary embodiments are described as processes or methods depicted as flow charts. Although the flow charts describe the steps as sequential processes, many of the steps therein can be implemented in parallel, concurrently or simultaneously. In addition, the order of the steps can be rearranged. The process can be terminated when its operation is completed, but can also have additional steps not included in the accompanying drawings. The process can correspond to a method, function, procedure, subroutine, subprogram, etc.

[0023] Figure 1 It is a flowchart of the method for identifying the audio data encapsulation format provided in an embodiment of the present application. This embodiment can be applicable to the case of audio decapsulation. The method can be executed by the audio data encapsulation format identification device provided in an embodiment of the present application. The device can be implemented by software and / or hardware and can be integrated in devices such as smart terminals.

[0024] like Figure 1 As shown, the method for identifying the audio data encapsulation format includes:

[0025] S110: If audio data in an unknown encapsulation format is detected, the audio data is processed using a first decapsulation rule to obtain first original data; and the audio data is processed using a second decapsulation rule to obtain second original data.

[0026] The audio data may be separately recorded audio data or audio data transmitted along with the video stream. The audio data is transmitted after being encapsulated. Therefore, the encapsulation format is like a key to the audio data. Only by knowing the correct encapsulation format can the content of the audio data be obtained. Therefore, after detecting audio data with an unknown encapsulation format, it is necessary to determine the encapsulation format.

[0027] The audio data is processed using a first decapsulation rule to obtain first original data; and the audio data is processed using a second decapsulation rule to obtain second original data. It is understandable that the first decapsulation rule may be a rule that matches the first encapsulation format, and the audio data may be encapsulated using the first encapsulation format, and then the first decapsulation rule is used to decapsulate the audio data to obtain the original audio data. The second decapsulation rule is similar. Therefore, in the case of an unknown audio encapsulation format, two decapsulation rules may be used to decapsulate the audio data to obtain two original data. Of course, in the case of a large number of audio encapsulation formats, more rules may be used to decapsulate the audio data, which will not be described in detail here.

[0028] In this solution, the first original data and the second original data may be PCM (Pulse Code Modulation) data.

[0029] It can be understood that one of the two original data is real original data and the other is wrong original data. For example, after being encapsulated in the first encapsulation format, the real original data can be obtained by using the first decapsulation rule, while the wrong original data is obtained by using the second decapsulation rule.

[0030] In this embodiment, optionally, the first decapsulation rule is a G711A decapsulation rule, and the second decapsulation rule is a G711U decapsulation rule.

[0031] From the previous introduction, we can know that G711A and G711U are two encapsulation formats, each with its own focus. Since the encoding principles of the two encapsulation formats are different, the original data obtained by using the two decapsulation rules are also different.

[0032] Here are two encoding rules:

[0033] Figure 2 is a schematic diagram of the encoding rule of G711A provided in the embodiment of the present application, such as Figure 2 As shown, for G711A, the encoding rules are:

[0034] 1. Take the sign bit and invert it to get S;

[0035] 2. Get the intensity bit eee, the acquisition method is as follows Figure 2 ;

[0036] 3. Get the high-order sample bit wxyz;

[0037] 4. The combination is seeewxyz, and the complement of seeewxyz is taken when it is an even number. The encoding is completed.

[0038] Figure 3 is a schematic diagram of the encoding rule of G711U provided in the embodiment of the present application, such as Figure 3 As shown, for G711U, the encoding rules are:

[0039] For example: PCM=2345;

[0040] 1. Get the range value +4062 to +2015 in 16 intervals of 128 to get the base value 0x90;

[0041] 2. Interval number 128;

[0042] 3. The basic value of the interval is 4062;

[0043] 4. The difference between the current value 2345 and the interval basic value is 4062-2345=1717;

[0044] 5. Offset value = 1717 / interval number = 1717 / 128 to get the integer 13;

[0045] 6. Output 0x90+13=0x9D.

[0046] Therefore, by reversing the encoding rules of G711A and G711U, the original uncompressed PCM audio data can be obtained.

[0047] S120: Acquire a first parameter and a second parameter of the first original data, and acquire a first parameter and a second parameter of the second original data.

[0048] The first original data and the second original data may be stored in a certain storage location in the form of binary data. The first parameter and the second parameter are obtained by reading the information therein or parsing the data therein. The first parameter and the second parameter may be the duration and amplitude of the two original data, or other data. It is understandable that as long as the two parameters can be used to distinguish which is the correct original data and which is the incorrect original data, it is sufficient.

[0049] In this solution, optionally, the first parameter includes the average decibel; the second parameter includes the decibel variance. The average decibel is determined based on the amplitude value of the waveform of the original data, which can be the average value of the decibel over a period of time. The decibel variance is calculated based on the average decibel and the decibel value of each sampling point.

[0050] In this solution, based on data analysis, the two parameters with the greatest difference between the correct original data and the wrong original data, or the two parameters with the most stable difference, are determined. For example, after encapsulation in one encapsulation format, two decapsulation rules are used for decapsulation, then there must be one correct original data and one wrong original data. The most stable difference mentioned here can be a parameter that is selected from multiple parameters, and there will be obvious differences as long as the correct original data and the wrong original data are compared. After using these two parameters to characterize the original data, the correct original data and the wrong original data can be clearly compared.

[0051] In this solution, optionally, the average decibel is determined in the following manner:

[0052] Determine the total amplitude of the original data according to the sampling point values ​​of the original data; wherein the original data is the first original data or the second original data;

[0053] Determine the average amplitude according to the total amplitude and the number of sampling points of the original data;

[0054] Substituting the average amplitude into a preset decibel calculation formula to obtain the average decibel;

[0055] The decibel variance is determined in the following manner:

[0056] The decibel variance is obtained according to the decibel of each sampling point and the average decibel.

[0057] Specifically, the average decibel can be calculated by finding the average amplitude, and then substituting the average amplitude into a preset decibel calculation formula to obtain the average decibel.

[0058] The highest and lowest decibels at each sampling point of the PCM audio data are then used to calculate the average decibel and variance of the PCM based on the collected information. The default decibel calculation formula is as follows:

[0059]

[0060] Among them, L p is the sound decibel value, P rms is the amplitude value of the current sampling point; P ref The maximum value of the total amplitude of the sound.

[0061] Two bytes represent one sampling point. For example, 1Mb of data may include 512 sampling points. The value in the two bytes is the amplitude. The total amplitude is obtained by traversing the original PCM data.

[0062]

[0063] Calculate the average amplitude aver = sum / pcm[].size;

[0064] Calculate the average decibel db = (int)(20.0*log10(aver));

[0065] The variance calculation of decibels can be implemented using the following code:

[0066] Calculate the decibel of each sampling point, perdb[i]=20log10(pcm[i]);

[0067] Using the variance formula, substitute the decibel perdb[i] of each sampling point into xi, where M is the average decibel db;

[0068] n is pcm[].size, and the final decibel variance sdb is obtained;

[0069] Here, it is worth explaining that the sampling point value of the original data can be used to characterize the amplitude of each sampling point of the original data, including the positive amplitude and the reverse amplitude. Assuming that the positive amplitude is a positive value, the reverse amplitude is a negative value in the amplitude curve. Therefore, when calculating the total amplitude, it is necessary to remove the absolute value of the negative value to obtain the true total amplitude.

[0070] Through the above calculation, this solution can use a clear algorithm to determine the specific values ​​of the two parameters, so that during the implementation of the solution, no manual setting is required and it can be applied to any situation.

[0071] In the technical solution, optionally, determining the total amplitude of the original data according to the sampling point values ​​of the original data includes:

[0072] Determine the sum of the absolute values ​​of the amplitudes of all sampling points in the original data as the total amplitude of the original data.

[0073] The sum of the absolute values ​​of the amplitudes of all sampling points is taken as the total amplitude of the original data. It can be understood that for a section of audio data, a certain range can be intercepted as test data for determining the encoding format of the audio data. Therefore, all the sampling points here can be for the entire audio data or only for the test data. In this way, the amount of calculation can be reduced and the calculation speed can be increased by intercepting the test data.

[0074] S130: If the first parameter of the first original data and the first parameter of the second original data satisfy a preset numerical relationship, and the second parameter of the first original data and the second parameter of the second original data satisfy a preset numerical relationship, determine an audio data encapsulation format.

[0075] The preset numerical relationship may be a magnitude relationship between numerical values ​​or a positive and negative relationship between numerical values. In this solution, the correct decapsulation rule may be determined based on whether the first parameters of the two original data satisfy the preset numerical relationship and the second parameters of the two original data satisfy the preset numerical relationship, thereby determining the audio data encapsulation format.

[0076] In the technical solution, optionally, if a first parameter of the first original data and a first parameter of the second original data satisfy a preset numerical relationship, and a second parameter of the first original data and a second parameter of the second original data satisfy a preset numerical relationship, determining the audio data encapsulation format includes:

[0077] If the first parameter of the first original data is greater than the first parameter of the second original data, and the second parameter of the first original data is greater than the second parameter of the second original data, determining that the audio data encapsulation format is the second encapsulation format;

[0078] If the first parameter of the first original data is smaller than the first parameter of the second original data, and the second parameter of the first original data is smaller than the second parameter of the second original data, determining that the audio data encapsulation format is the first encapsulation format;

[0079] The first encapsulation format and the first decapsulation rule are inverse operations of each other, and the second encapsulation format and the second decapsulation rule are inverse operations of each other.

[0080] Among them, the first parameter can be the average decibel, and the second parameter can be the decibel variance. Since one encapsulation format is used for encapsulation and another decapsulation rule is used for decapsulation, the original data will be distorted, the decibel at the sampling point will be greater than normal, and the fluctuation range will be larger. Therefore, the average decibel and the variance will be greater than the original data obtained by the normal decapsulation rule.

[0081] For example, the original G711A audio data is abnormally magnified according to the audio waveform after being decapsulated by G711U. Based on this phenomenon, the average decibel of the audio data can be calculated by calculating the decibel of each sampling point of the decapsulated PCM audio data, and then the variance of the decibel of the entire PCM audio data is calculated, and the decibel variance and average decibel of the two sets of data are compared. The larger the decibel variance and the larger the average decibel, the greater the audio fluctuation amplitude and the greater the frequency, and it is considered that the decapsulation rule is wrong. The smaller the decibel variance and the average decibel, the correct decapsulation rule is considered.

[0082] The technical solution provided by the present application is to restore the original PCM data of the audio data in advance according to the encoding principles of G711A and G711U, and then calculate the decibel average and decibel variance based on the restored PCM data, and further analyze and compare to obtain the most matching encoding format, so as to obtain the correct encoding format of the original audio in the absence of bit stream information, and use the corresponding decapsulation rules to perform decapsulation processing to obtain better playback effect.

[0083] The technical solution provided in the embodiment of the present application, if audio data of unknown encapsulation format is detected, the audio data is processed using a first decapsulation rule to obtain first original data; the audio data is processed using a second decapsulation rule to obtain second original data; the first parameter and the second parameter of the first original data are obtained, and the first parameter and the second parameter of the second original data are obtained; if the first parameter of the first original data and the first parameter of the second original data satisfy a preset numerical relationship, and the second parameter of the first original data and the second parameter of the second original data satisfy a preset numerical relationship, then the audio data encapsulation format is determined. The technical solution provided in the present application can quickly and accurately determine the encoding format, so that the encoding format that meets the actual needs can be used for decoding, and the purpose of stably restoring the original audio data can be achieved.

[0084] It can be understood that according to the actual situation, when the first parameter can be the average decibel and the second parameter can be the decibel variance, there is no situation where the first parameter of the first original data is greater than the first parameter of the second original data, and the second parameter of the first original data is less than the second parameter of the second original data, or the first parameter of the first original data is less than the first parameter of the second original data, and the second parameter of the first original data is greater than the second parameter of the second original data. Therefore, if this situation exists in the test, an error processing can be performed and the sampling point can be reselected for calculation.
