Fig. 3 is a flowchart of a sound effect matching method applied to the media playing device 100 shown in fig. 1 according to an embodiment of the present invention. It should be noted that the method provided by the present invention is not limited by the specific sequence shown in fig. 3 and described below. The steps shown in fig. 3 are explained in detail below.
Step S101, acquiring attribute information of the audio file.
The audio files described in this embodiment include music files, such as music files in MP3 format, music files in WMA format, music files in WAV format, and the like. In the following description, no particular explanation is made, and the mentioned audio file is exemplified by the music file.
An audio file is usually composed of three parts, a header, audio data, and a trailer. Currently, attribute information of an audio file is generally stored in the file header. For example, in the case of an audio file in the MP3 format, most of the attribute information is stored in the ID3V2 tag located in the header.
The attribute information of the audio file includes one or more of a plurality of tag information such as singer information, year of production, album information, genre type, and genre type of album. Wherein the genre type is one of a plurality of sound effect modes suitable for playing the audio file. The genre type may be, but is not limited to, Pop mode (Pop), Jazz mode (Jazz), Rock mode (Rock), classical mode (Classic), blue mode (Blues), Hip-Hop mode (Hip-Hop), Disco mode (Disco), and normal mode (Nomal), etc.
Generally, attribute information of each audio file is labeled with singer information, but whether the rest of label information is contained depends on different audio files. That is, in this embodiment, the attribute information obtained from the header of the audio file should at least include singer information corresponding to the audio file.
In addition, although the attribute information of the existing partial audio file is labeled with the genre type or the genre type of the album, the accuracy thereof is not reliable. For example, in a network music platform (e.g., a hot dog music), the tag information related to genre types of music files stored in the background database is added to the attribute information in batch, and is not checked one by one. Therefore, it is not feasible to determine the sound effect mode of the audio file only by the genre type indicated in the attribute information.
And step S103, determining a sound effect mode matched with the audio file according to the attribute information.
In this embodiment, after the attribute information of the audio file is acquired, the attribute information is searched in a pre-stored database according to the acquired attribute information, and a sound effect mode matched with the audio file is determined. The database may be a terminal database stored in the media playback device 100, or may be a network database stored in the server 200. When the database is a network database, the media playing device 100 establishes a communication connection with the server 200 through a wireless or wired network. After acquiring the attribute information of the audio file, the media playing device 100 sends the attribute information to the server 200, so that the server 200 searches the network database according to the received attribute information to determine the sound effect mode of the audio file. Then, the server 200 returns the found sound effect mode to the media playing device 100.
The database may be updated in real time or periodically. When the database is a terminal database, the media playing device 100 may access the server 200 according to a predetermined period, and download the updated data to the terminal database, or the server 200 pushes the updated data to the media playing device 100 in real time.
It will of course be appreciated that the database is preferably a network database in general. Because the database is stored in the cloud, the local storage space of the terminal is not occupied, a user can use the latest data at any time without upgrading the client, and the terminal cannot bring hidden system troubles due to the increasingly huge database.
The database stores a data list as shown in fig. 4. Of course, it is understood that the data list is merely exemplary, and in other embodiments, the data stored in the database may be stored in other data structures.
The data list may be obtained through a large amount of data collection and analysis. Specifically, the published musical pieces, including albums, single songs, etc., may be acquired from the network to the maximum extent for each singer. Then, data analysis is performed on all the acquired musical pieces of the singer to determine a main genre thereof, that is, a genre to which most or all of the musical pieces belong. Then, the musical pieces are divided by the production years, the genre type of the artist's year is determined, and the genre type of the album is determined based on the album information. Wherein the genre type of the year is a genre type to which most or all of the musical pieces produced by the singer in the current year belong.
For example, suppose singer a produced eight albums and two single songs from 2001 to date. Wherein, the genre types of six albums and two single songs are popular music, and the other two albums are classical music. Thus, the mainstream genre of the singer a can be determined as the pop mode. Then, all musical pieces are divided by the year of production. Five pop music albums and one pop music single song are produced in the 00 s, and the genre type of the 00 s is a pop music mode. Three albums and a single song are produced in the 10 s, wherein one album and the single song are popular music, and the other two albums are classical music, so that the genre type of the 10 s is a classical music mode.
In this embodiment, since the number of the tag information included in the attribute information of different audio files is different, the manner of determining the sound effect mode by searching the database according to the attribute information is also different.
As shown in fig. 5, if the attribute information obtained as described above only includes singer information, step S103 includes the following sub-steps:
substep S131: and searching in the database according to the singer information to obtain the main dispatch type corresponding to the singer information.
Substep S133: and determining a sound effect mode matched with the audio file according to the main dispatch type.
When only singer information is written in the attribute information of the audio file, the corresponding main dispatch type can be searched in the database according to the singer information, and then the sound effect mode matched with the audio file is determined. Although the determination method of the sound effect mode is not absolutely accurate, statistics proves that the accuracy is very high, the technical implementation is simple, a large amount of calculation overhead is not needed, and the practicability is high.
As shown in fig. 6, if the attribute information obtained as described above includes tag information in addition to singer information, step S103 includes substeps 125 to 129, as follows, before substep S131 shown in fig. 5. Wherein the attached tag information includes at least one of the production age information and the album information of the audio file. In this embodiment, the album information may be, but is not limited to, an album name.
Substep S125: and searching a distribution type corresponding to the singer information and the attached label information in the prestored database according to the singer information and the attached label information in the attribute information.
In this embodiment, the genre type is a chronological genre type or an album genre type. Specifically, when the attached tag information only includes the production year information, the database may be searched for the singer information and the production year information, and the genre type of the year when the singer corresponds to the production year may be obtained. And when the auxiliary tag information only comprises album information, searching in the database according to the singer information and the album information to obtain the corresponding album genre type. When the attached tag information includes both the production year information and the album information, the year genre type and the album genre type are obtained according to the above searching method, and when the two types are different, the album genre type may be used as the standard.
Of course, in some embodiments, there may be cases where no genre-type is found. Thus, the following substeps may be performed.
And a substep S127 of judging whether the genre type is found. If the search is found, the following substep S129 is performed, and if the search is not found, the process returns to substep S131.
And a substep S129, directly determining a sound effect mode matched with the audio file according to the shunting type.
As shown in fig. 7, if the obtained attribute information is labeled with at least one of genre type information corresponding to the audio file and genre type information corresponding to the album on which the audio file is located, in addition to singer information, step S103 further includes sub-step 141 before sub-step S133 shown in fig. 5 or 6.
Substep S141: and judging whether the main genre type is consistent with the genre type information marked in the attribute information. If they match, substep S133 is executed, and if they do not match, substep S143 is executed.
In this embodiment, if the genre type information labeled in the attribute information only includes a genre type corresponding to the audio file, it is only necessary to determine whether the main genre type is consistent with the genre type corresponding to the audio file. If the genre type information marked in the attribute information only includes genre type information corresponding to the album where the audio file is located, it is only necessary to determine whether the main genre type is consistent with the genre type information corresponding to the album where the audio file is located. If the genre type information labeled in the attribute information includes both the genre type information corresponding to the album in which the audio file is located and the genre type corresponding to the audio file, it can be determined whether the main genre type is consistent with the two genre type information. Alternatively, in another embodiment, it may be determined whether the main genre type is consistent with one of the two genre type information.
Substep S143: and converting according to a preset weighting proportion to determine a final genre type, and determining a sound effect mode matched with the audio file according to the final genre type.
As mentioned in the foregoing, the accuracy of the genre type information labeled in the attribute information of the audio file is low, so that it is not feasible to determine the acoustics mode of the audio file directly from the genre type information in the attribute information.
When the main genre type determined by the singer information is consistent with the genre type information labeled in the attribute information, it can be said that the accuracy of the sound effect mode determined by the main genre type is further enhanced. When the main genre type is inconsistent with the genre type information marked in the attribute information, in this embodiment, the final genre type may be determined by performing conversion according to a predetermined weighting ratio.
The conversion according to the predetermined weighting ratio may be that the mainstream genre and the genre type information labeled in the attribute information are weighted and calculated according to a certain weighting ratio. Then, one of the largest weight ratios is determined as the final genre type. For example, in an embodiment, the weight proportion of the main genre is 60%, the weight proportion of the genre type information of the audio file is 20%, and the weight proportion of the genre type information corresponding to the album on which the audio file is located is 20%, then the final genre type is determined as the main genre type.
It will be appreciated that different weighting ratios may be set for different singers or music on different platforms. As mentioned above, the genre type information labeled in the attribute information is usually inaccurate, but it is not excluded that the genre type information included in the attribute information is accurate in the audio file corresponding to a singer. Therefore, specific weighting ratio division can be performed for this kind of singer, for example, the weight ratio occupied by the main genre is 30%, the weight ratio occupied by the genre type information of the audio file is 40%, and the weight ratio occupied by the genre type information corresponding to the album where the audio file is located is 30%. Or, the weight ratio occupied by the main genre type is 45%, and the weight ratio occupied by the genre type information of the audio file is 55%.
Step S105, playing the audio file according to the sound effect mode.
In this embodiment, after the media playing device 100 determines the sound effect mode matched with the audio file, the audio player 130 sets audio playing parameters according to the sound effect mode, and plays the audio file.
It should be noted here that the media playing device 100 may also be a combination device, such as a combination of a PC (personal computer) and a smart speaker. The PC is used for acquiring attribute information of the audio file and determining a matched sound effect mode according to the attribute information. And then, the PC sends the sound effect mode to the intelligent sound box, so that the intelligent sound box sets audio playing parameters according to the received sound effect mode and plays the audio file.
In addition, it should be noted that, in other embodiments, the database may also perform data update according to feedback information of the user, so as to further improve the accuracy of the sound effect mode determined by the sound effect matching method.
