The words "first" and "second" as used herein are limited to distinguishing between different objects and are not intended to limit the order of the two objects. The objects referred to herein are the players, servers, audio folders, and the like mentioned in the various embodiments described below.

1 is a flowchart of a method for generating a song list according to an embodiment of the present invention. The method for generating a song list is applied to a terminal in which a first player and a second player are installed, and the terminal may be a smart phone or a multimedia player. Tablets, etc. As shown in FIG. 1, the song list generation method includes the following steps.

In step 101, the first audio folder corresponding to the second player is read by the first player, and the first audio folder is used to store the audio file in the second player song list.

The first player is an application installed in the terminal for playing an audio file, and the second player Another application installed for the terminal to play audio files.

Generally, the first player and the second player correspond to different servers, the first player corresponds to one server, and the second player corresponds to another server.

For example, the first player corresponds to the first server, and the second player corresponds to the second server. The database of audio files provided by the first server and the database of audio files provided by the second server may be the same or different. The first player downloads an audio file from the first server, and the second player downloads the audio file from the second server.

After the terminal installs the player, if the player downloads the audio file from the corresponding server, the player generates an audio folder for storing the audio file downloaded by the player at the terminal. When the audio folder is generated, it may be a folder created by the player by default in the player installation directory, or the user may specify the storage location of the folder.

In various embodiments of the present invention, a folder for storing an audio file downloaded by the first player is recorded as a second audio folder, and a second player is used for storing an audio file downloaded by the second player. The folder is recorded as the first audio folder.

In step 102, fingerprint features of respective audio files in the first audio folder are obtained, and the fingerprint features are used to uniquely identify the audio file.

In step 103, for the fingerprint feature of each of the acquired audio files, the audio file information of the audio file having the fingerprint feature is acquired from the server corresponding to the first player.

In step 104, a song list of the first player is generated using the acquired individual audio file information.

In summary, the method for generating a song list provided by the embodiment of the present invention reads the first audio folder stored in the terminal by the second player by using the first player, and acquires each audio file in the first audio folder. a fingerprint feature, so as to obtain audio file information of the audio file having the fingerprint feature from the download server corresponding to the first player, and use the audio file information to generate a song list of the first player; since the first player can be according to the second The audio folder of the player automatically generates a song list corresponding to each audio file in the audio folder, and the user no longer needs to manually search for the audio file located in the first audio folder in the search box of the first player. Therefore, the problem of cumbersome steps in the process of transplanting songs between different players in the related art is solved; the steps of simplifying the transplantation of songs between different players are achieved, and the transplantation of songs between different players is improved. The effect of efficiency.

2A is a flowchart of a method for generating a song list according to another embodiment of the present invention. The method for generating a song list is applied to a terminal in which a first player and a second player are installed, and the terminal may be a smart hand. Machines, multimedia players, tablets, etc. As shown in FIG. 2A, the song list generation method includes the following steps.

In step 201, the first audio folder corresponding to the second player is read by the first player, and the first audio folder is used to store the audio file in the second player song list.

After the second player downloads the audio file in the second player song list to the terminal, the second player saves the downloaded audio file in the audio folder corresponding to the second player by default.

The player can have multiple song lists, one song list generally corresponds to one audio folder, and the audio folder stores all the audio files on the song list corresponding to the audio folder.

If the user installs a first player different from the second player on the terminal, and wants to transplant the song list created in the second player to the first player, the user can create a song in the first player. In the single function, choose to import the local song list. Since the audio file in the song list is stored locally in the form of a folder, when the user selects the first audio folder corresponding to the locally stored second player song list in the operation interface of the first player The first player can read the first audio folder corresponding to the second player according to the user's selection.

2B is a schematic diagram of a first player interface provided in an embodiment of the present invention. As shown in FIG. 2B, the user clicks the add song list function 11 in the first player interface 10, and selects “Import Local Songs”. The option of 12, triggering the import interface, please refer to FIG. 2C, which is a schematic diagram of an interface for importing a local song list by the first player provided in an embodiment of the present invention. As shown in FIG. 2C, the user is in the import interface 13. Selecting the subdirectory "first audio folder" 14 in the second player folder, the first player can acquire all the audio file information in the first audio folder in the second player.

After the first player reads the first audio folder corresponding to the second player, the audio file information of the audio file in the first audio folder is obtained from the server corresponding to the first player, so as to utilize the audio file. The information generates a song list of the first player. For details, refer to the implementation in steps 202 to 204.

In step 202, fingerprint features of respective audio files in the first audio folder are obtained, and the fingerprint features are used to uniquely identify the audio file.

The fingerprint feature mentioned here is used to uniquely identify the audio file, that is, the fingerprint feature is used to uniquely identify the tune, singer, lyrics, voiceprint and other information of the audio file, when the two songs are tune, singer, lyrics, and sound. When at least one of the patterns is different, the corresponding fingerprint features are also different, so obtaining the fingerprint feature of the audio file can obtain valid information identifying the audio file.

In a possible implementation, please refer to FIG. 2D, which is shown according to an embodiment. A flowchart for taking a fingerprint feature of an audio file, as shown in FIG. 2D, the method for obtaining a fingerprint feature of an audio file includes the following steps:

In step 202a, the format of the audio file is converted to a pulse code modulated PCM format for each audio file in the first audio folder.

The process of converting the original format of an audio file into a pulse code modulation (PCM) format is: sampling an analog signal such as a voice or an image every predetermined time period to discretize it, and obtaining the sampled sample. The sampled values are rounded up by the rounding unit, and the sampled values are represented by a set of binary codes to represent the amplitude of the sampled pulses.

At present, the audio files downloaded by the player are mostly compressed picture experts group audio layer 3 (MP3) format. In order to obtain the spectrum information of the audio file, the MP3 format is usually converted into the PCM format.

In step 202b, the spectrum of the audio file having the PCM format is extracted, and the peak point between the peak points in the spectrum smaller than the predetermined frequency is filtered by the Fourier transform.

After converting the original format of the audio file to the PCM format, the spectrum of the audio file is generated.

At present, some audio files in the player's audio file library are processed by post-human bass enhancement or treble modification, and the spectrum generated by the audio file will change, that is, the peak points of the audio file spectrum will overlap and closely overlap. The phenomenon. In order to make the distribution of the selected peak points along the time and frequency axis relatively uniform, to ensure the accuracy of the fingerprint matching of the audio file in the subsequent steps, the audio file audio can be filtered by using Gaussian filtering to effectively eliminate the audio in the audio. noise.

One of the implementations of Gaussian filtering is the Fourier transform, that is, the Fourier transform can be used in this embodiment to eliminate noise in the audio file spectrum. 2E is a schematic diagram of the peak frequency of the filtered audio file provided in an embodiment of the present invention. As shown in FIG. 2E, the distribution of the frequency peak points of the audio file segment before filtering is overlapped and closely attached. The Fourier transform filters the audio file segment, and after filtering out the peak point less than the predetermined frequency between the peak points, the distribution of the peak point along the time and frequency axis is relatively uniform, wherein the predetermined frequency may be 10 kHz, 20 kHz. Etc., the size of the predetermined frequency is not limited here.

In step 202c, at least two segments of discontinuous spectrum having a predetermined duration are intercepted from the filtered spectrum.

In step 202d, the intercepted segments of the spectrum are combined into a fingerprint feature of the audio file.

Taking the same song as an example, the PCM audio format of the audio file occupies a large storage space relative to an audio format such as an MP3 audio file, and if the terminal has the PCM format of the audio file. The time required for the spectrum to be sent to the server is long; if the terminal is in the data networking state, the sending process may fail due to the instability of the network data. Therefore, the terminal can intercept the filtered spectrum into a spectrum having a predetermined duration, and use the intercepted spectrum as a fingerprint feature of the audio file.

In order to prevent the intercepted audio file from being a stringed audio file or a stringed audio file in the server, the matching result of matching using only one piece of the spectrum segment is inaccurate. In a preferred manner, it can be from the filtered spectrum. And intercepting at least two segments of the discontinuous spectrum having a predetermined duration, and combining the intercepted segments into a fingerprint feature of the audio file.

The predetermined duration can be set according to the actual situation or experimental analysis. After a large number of experimental analysis, when the predetermined duration is 10 seconds, the required storage space of the PCM format spectrum is suitable, and the server matches according to the 10 second spectrum in the subsequent steps. The matching result is more accurate. Here, the specific numerical value of the predetermined duration is not limited.

In step 203, for the fingerprint feature of each of the acquired audio files, the audio file information of the audio file having the fingerprint feature is acquired from the server corresponding to the first player.

For obtaining the fingerprint feature of each audio file, the terminal sends the fingerprint feature of the audio file to the server corresponding to the first player, and the server searches for the audio file matched by the fingerprint feature stored in the server, and the feedback and fingerprint feature The matched audio file; correspondingly, the terminal receives the audio file matched by the server and matched with the fingerprint feature.

After receiving the fingerprint feature of the audio file, the server corresponding to the first player matches the fingerprint feature with the audio file stored in the server, and matches the audio file corresponding to the fingerprint feature in the audio file library. When the degree reaches the predetermined matching degree, it can be determined that the two titles are the same audio file.

Because the number of audio files stored by the server is large, if the traditional search mode is used to match the audio files one by one, the server will increase the amount of computation and consume more matching time, so the server can use the hash structure to optimize. Matching efficiency, the hash structure is to divide an entire data block into n sub-blocks, and then perform parallel processing on n sub-blocks to realize processing of an entire block.

For example, if the predetermined matching degree is 80%, if the server divides the fingerprint feature of the first audio file into 10 sub-fingerprint features, when the first audio file has at least 8 sub-fingerprint features and B audio files in the audio file library. The fingerprint features are the same, that is, it is determined that the sub-fingerprint feature of the A audio file and the B audio file fingerprint feature reach a predetermined matching degree, then it is determined that the B audio file and the A audio file are the same song, and the B audio file is fed back to the terminal.

That is, the server divides the fingerprint feature of the first audio file into n (n is a natural number greater than 0) sub-fingerprint features, and respectively matches the n sub-fingerprint features with the fingerprint features of the audio file stored in the server, when the first audio The sub-fingerprint feature of the file and the fingerprint feature of the second audio file in the server reach a predetermined matching degree, and then the first audio file and the second audio file are determined to be the same first audio file.

In step 204, a song list of the first player is generated using the acquired individual audio file information.

In an actual application, the terminal can generate a song list for the first player according to each audio file information. For example, the terminal generates a root directory for the song list of the first player, and uses the name of the audio file in each obtained audio file information as A subdirectory of the root directory that generates a song list for the first player.

Preferably, the first player of the terminal sends the generated song list to the server by using the logged-in user account, so that the server binds the song list with the user account, so that the user account is the first player on the other terminal. When logging in, the song list bound to the user account can still be pulled through the first player, that is, the new song list bound with the user account can be roamed to other terminals through the server.

In one possible case, the song list name can be generated automatically or set and modified by the user. Therefore, after step 204, the method may further include: receiving a setting instruction for setting a root directory of the song list, and setting a name of a root directory of the song list to a name set by the setting instruction.

Optionally, after the root name of the song list is generated or set successfully, the root directory name may also be modified. The specific process may include: receiving a modification instruction for the root directory of the song list; and the name of the root directory of the song list Modified to modify the name indicated by the instruction.

In an actual application, the terminal may also use the audio file information to download the corresponding audio file from the server in advance. For details, refer to the following

steps

205 and 206.

In step 205, the audio file having the audio file information is downloaded from the server corresponding to the first player using the audio file information.

In step 206, the downloaded search audio file is stored in a second audio folder corresponding to the first player, and the name of the second audio folder is named as a name corresponding to the root directory.

After the first player downloads the corresponding audio file from the server by using the audio file information, the audio file may be uniformly stored in the second audio folder corresponding to the first player, in order to play the second audio folder with the first audio folder. The song list of the device corresponds, and the name of the second audio folder can be named as the name corresponding to the root directory of the song list of the first player.

In summary, the method for generating a song list provided by the embodiment of the present invention reads the first audio folder stored in the terminal by the second player by using the first player, and acquires each audio file in the first audio folder. Fingerprint feature to facilitate obtaining fingerprint features from a download server corresponding to the first player Audio file information of the audio file, using the audio file information to generate a song list of the first player; since the first player can automatically generate an audio file corresponding to each audio file in the audio folder according to the audio folder of the second player The song list no longer requires the user to manually search for the audio file located in the first audio folder in the search box of the first player, thereby solving the cumbersome steps in the related art in the process of transplanting the songs between different players. The problem is that the steps of transplanting songs between different players can be simplified to a large extent, and the effect of transplanting songs between different players is improved.

In addition, by converting the audio file into the PCM format and then Gaussian noise reduction on the audio file spectrum, the accuracy of the fingerprint matching of the audio file can be improved.

In a possible case, when the server corresponding to the first player receives the fingerprint feature of the audio file sent by the terminal, and detects that there is a version higher than the quality of the audio file in the server, in order to be able to provide the required user. A high-quality audio file is provided, and the user can be prompted to upgrade the quality of the audio file. In this case, the terminal can select whether to upgrade according to the upgrade notification prompted by the server, which may include the following four steps:

Step 1: Receive an upgrade notification sent by a server corresponding to the first player, where the upgrade notification is used by the server to prompt the user to select when the server stores a version higher than the quality of the audio file according to the fingerprint feature of the audio file. One of the versions is notified of the upgrade.

At present, the audio file quality version provided in the player has standard, high quality (English: high quality, HQ), super quality (English: super quality, SQ), etc., when the server detects the fingerprint feature of the audio file uploaded by the terminal. When the corresponding audio file stores a higher quality version in the server, the server may feed back an upgrade notification to the terminal, and the upgrade notification is used to prompt the user to select one of the versions to be upgraded to meet the user with higher music quality requirements. Demand.

Step two, the upgrade notification is displayed.

Referring to FIG. 2F, it is a schematic diagram of the terminal display prompt box provided by the terminal in the embodiment of the present invention to prompt the user whether to download a higher sound quality version of the audio file. As shown in FIG. 2F, after receiving the server feedback upgrade notification, the terminal 18 is at the terminal. The upgrade notification of the server feedback is displayed on the display of 18, and the upgrade notification can be displayed in the form of the upgrade notification box 19 to prompt the user to upgrade the sound quality of the audio file.

Step 3: Receive a selection instruction selected according to the upgrade notification, and the selection instruction carries the version identifier selected by the user.

The version identifier of the audio file is used to identify the version of the audio file quality, see Figure 2G, which is A terminal provided by an embodiment of the present invention displays an upgrade notification to notify a user of a quality version of an audio file. As shown in FIG. 2G, when the user selects a version of the audio file quality to be upgraded, the terminal 18 displays on the display screen. The upgrade notification 20 notifies the user to select the version of the music to be downloaded, and the selection instruction carries the version identifier selected by the user.

Step 4: Send a selection instruction to the server, and the selection instruction is used to trigger the server to feed back the audio file in the found audio file with the version identifier carried in the selection instruction.

Still referring to FIG. 2G, when the user selects “SQ Super Quality” 21 in the upgrade notification 20 displayed by the terminal 18 on the screen, the terminal sends the “SQ Super Quality” carrying the user selection to the server corresponding to the first player. The selection instruction of the version identifier, after receiving the selection instruction, the server feeds back to the terminal an audio file that matches the fingerprint feature sent by the terminal to the server, and the audio file quality version is the audio file quality version selected by the user.

Preferably, in order to be able to provide high quality service to users with high sound quality requirements, the provider of the first player may divide the user into different levels and provide audio file versions of different sound quality levels for different levels of users. For example, the server corresponding to the first player divides the user into ordinary users and high-level users, and provides a standard quality audio file version for ordinary users and a higher quality audio file version for high-level users.

Referring to FIG. 2H, which is a schematic diagram of a terminal display user level upgrade prompt box provided by the terminal in the embodiment of the present invention to prompt the user to upgrade the user level, as shown in FIG. 2H, when an ordinary user wants to download a high-quality version of the audio file.
