Specifically, when audio data is sent to wireless audio playback equipment by electronic equipment, for improve data transfer Speed is needed Audio data compression, to reduce the size of audio data, then the process is to encode to audio data. Specifically, there are a variety of for the audio data to be sent to the encryption algorithm of the wireless audio playback equipment, Mei Gebian Encoding rate corresponding to code algorithm is different, i.e., when different encryption algorithms is to the same audio data coding, obtained coding The size of audio data later is also different.

Wherein, electronic equipment is sent to what wireless audio playback equipment played to by sound from the sound that user inputs is received Process, including analog signal sampling, quantization and the coding to sound.Sound is the signal of Time Continuous, by the sound The digitlization of the signal, i.e. discretization are realized in sampling and quantization, to form audio data.For example, when if sound is one Between continuous sine curve, after electronic equipment gets the sound, for example, pass through microphone acquire.Electronic equipment is to this Sampled voice is at several points, this process is sampling.Obviously, sampling density is bigger, i.e., sample rate is bigger, obtained discrete Signal is just closer to former continuous signal.Since each sampled point will occupy memory space, therefore sample rate is higher, gained The audio data arrived is bigger.

Sampling is the first step of audio processing.After sampling, also the data of acquisition are stored.Storage is desirable Space, one second sampled data is stored with how many space, and here it is audio coding rates.As it can be seen that identical in sample rate Under the premise of, encoding rate is lower, and data are smaller.But two steps of sampling and coding can all reduce sound quality.Coding is actually Compression, encoding as mp3 is all lossy compression, thrown away most of human ear discover without sonic data, thus volume Very little.

Wherein, the raising of audio coding rate can be raising sample rate, be also possible to during coding, reduce nothing Discarding and the more useful informations of reservation with information, i.e. reduction compression ratio, for example, a kind of encryption algorithm, it will be in sound stream The 16bit data sampled every time are stored with 4bit, then compression ratio is 4:1, then have 25% useful information to be retained, and if will Compression ratio becomes 8bit, then compression ratio becomes 2:1, and compression ratio is reduced, and has 50% useful information to be retained, and more has It is retained with information, but the data quantitative change of audio data is bigger.

The above are in the cataloged procedure of sound to audio data, then after getting audio data, need audio number According to by Bluetooth transmission to wireless audio playback equipment, and in order to guarantee the speed of data transmission, need in accordance with electronic equipment with Bluetooth transmission protocol between wireless audio playback equipment is by audio data coding, to form the format of user's transmission, for example, on State by pcm encoder at SBC format, and in order to improve transmission speed and improve transmission serious forgiveness, need to adopt audio data Sample and coding, so that the size of audio data is reduced, convenient for transmission.Coding when similarly, for for transmitting audio data Rate increases, and can increase the compression ratio in the transmission to the sample rate of audio data or when reducing coding.Therefore, coding is calculated The corresponding encoding rate of method is higher, so that the useful information that audio data is lost is fewer, i.e. the sound quality of audio data is higher, still Audio data is formed by data packet data volume after being encoded is bigger.

Therefore, target user's account just can determine according to the corresponding relationship of the grade of above-mentioned encryption algorithm and user account number Number grade corresponding to encryption algorithm, it is contemplated that encryption algorithm corresponding to the grade of user account number be it is multiple, then need from An encryption algorithm is determined in multiple encryption algorithms as target code algorithm, specifically, according to the grade of the user account number It is corresponding with encryption algorithm according to the grade of preset user account number to determine that the specific embodiment of target code algorithm may is that Relationship determines encryption algorithm all corresponding to the grade of target user's account number, alternately encryption algorithm；By described The target code algorithm is determined in alternative encryption algorithm.

Wherein, in the grade of the user account number and the corresponding relationship of encryption algorithm, the higher grade of user account number, institute Corresponding encryption algorithm is more, further, can also be that the encoding rate of corresponding encryption algorithm is higher.Specifically, according to The grade of user account number described in above-mentioned table 2 and the corresponding relationship of encryption algorithm determine that target user's account number is corresponding all Encryption algorithm, alternately encryption algorithm, wherein if user account number not in the corresponding relationship described in the table 2, for example, with Family account number is new user, then can specifically join using the encryption algorithm of default as the alternative encryption algorithm of user account number Aforementioned embodiments are examined, details are not described herein.

After the alternative encryption algorithm of target user's account number has been determined, determine that target code is calculated from alternative encryption algorithm Method specifically determines an encryption algorithm as target code algorithm from alternative encryption algorithm.Specifically, it first determines alternative The quantity of encryption algorithm in encryption algorithm inputs the quantity equal to 1, then calculates the alternative encryption algorithm as target code Method can determine target code according to the use information of encryption algorithm each in alternative encryption algorithm if the quantity is greater than 1 Algorithm, wherein the use information includes access times, using time span or frequency of use, for example, access times are most Encryption algorithm is as target code algorithm.

As another embodiment, it can also be one encryption algorithm selection interface of interface display in electronic equipment, Target code algorithm is then determined according to the encryption algorithm selection interface.Specifically, as described in being determined in the alternative encryption algorithm The specific embodiment of target code algorithm are as follows: the code displaying algorithms selection interface in the display interface of the electronic equipment, The mark of each encryption algorithm in the alternative encryption algorithm is shown in the encryption algorithm selection interface；User is obtained to be based on The mark of the selected encryption algorithm of encryption algorithm selection interface；By the corresponding coding of the mark of selected encryption algorithm Algorithm is as target code algorithm.

Wherein, the display interface at code displaying algorithms selection interface can be the current display interface of electronic equipment, specifically The audio broadcast interface on ground, audio play-back application of the user in operation electronic equipment plays audio data to be played, For example, the playback of songs interface of some playback of songs software, as shown in figure 4, user chooses to be played in audio broadcast interface Song, i.e., audio data to be played, then click play button will code displaying algorithms selection interface.User is based on the volume Code algorithms selection interface, chooses an encryption algorithm, clicks and determines key, then electronic equipment is obtained user and selected based on encryption algorithm The selected encryption algorithm in interface is selected, using selected encryption algorithm as target code algorithm.Wherein, encryption algorithm selects boundary Face is a pop-up, in the area when electronic equipment shows the encryption algorithm selection interface, except the encryption algorithm selection interface Touch control operation accessed by domain is shielded, i.e., electronic equipment is not responding to user for the area except the encryption algorithm selection interface The touch control operation of domain input, and only after user selects encryption algorithm or clicks cancel button, it can just close the coding Algorithms selection interface.

In some embodiments it is contemplated that electronic equipment will affect user when code displaying algorithms selection interface Operation, therefore, electronic equipment obtain user be based on the selected encryption algorithm of encryption algorithm selection interface after, The encryption algorithm selection interface is no longer shown in preset time period, but persistently using user selected by the encryption algorithm selection interface The encryption algorithm selected obtains user in electronic equipment and is based on selected by the encryption algorithm selection interface as target code algorithm After the encryption algorithm selected, keeps the corresponding target code algorithm of target user's account number constant within a preset period of time, remove non-electrical Sub- equipment replacement user account number or preset time period terminate, then redefine target code algorithm.Wherein, preset time period For to obtain time point of the user based on the selected encryption algorithm of encryption algorithm selection interface as the time in electronic equipment Certain time length after starting point.
