The noun explains:
MIDI, commonly referred to as Musical Instrument Digital Interface, is a widely used music standard format.
According to an aspect of the embodiment of the invention, a method for pushing an audio file is provided. In this embodiment, the method for pushing the audio file may be applied to a hardware environment formed by the server 101 shown in fig. 1, and optionally, the hardware environment may further include the user terminal 102 logged with the target account. As shown in fig. 1, a user terminal 102 is connected to a server 101 via a network including, but not limited to: the user terminal 102 includes, but is not limited to, a mobile terminal such as a mobile phone or a tablet computer, and a computer terminal such as a personal computer PC.
Fig. 2 is a flowchart of a push method of an audio file according to an embodiment of the present invention. The pushing method of the audio file may be, but is not limited to be, executed by the server 101, as shown in fig. 2, for example, executed by the server 101, and the pushing method of the audio file includes the following steps:
s202, the server receives a playing instruction sent by the target account, and the playing instruction is used for indicating to play the audio file with the first identifier.
The play instruction may be sent by searching for a first identifier, which may be the name of the song, the name of the artist, the name of the movie associated with the song, and so on. For example, the user inputs a song title through a search box to instruct playing of an accompaniment audio file related to the song title. The accompaniment audio file of the song corresponding to the song name is the audio file with the first identification.
The audio file can be played on a user terminal, and a target account is logged on the user terminal, for example, the target account is logged on an audio client installed on the user terminal.
And S204, the server acquires the range of the vocal range of the target account according to the historical singing data of the target account.
The register range is the range of notes that fit the target account to sing. The note may represent a tone, and both the high tone and the low tone are not easy to sing, and the range of the note good at the target account may be obtained according to the historical sing data of the target account, that is, the range of the pitch range of the target account is determined.
S206, responding to the playing instruction, the server searches the target audio file with the first identification according to the range of the range, and the range of the target audio file is matched with the range of the range.
And searching a target audio file in an audio database, wherein the target audio file is a file with a first identifier, namely an accompaniment audio file which is the same as the first identifier in the audio files searched by the target account. For example, the target account number searches for "XXXXX", and the target audio file searched for is the accompaniment audio file of "XXXXX". The range of the target audio file is matched with the range of the range, for example, the target account number is male voice, the original singing is female voice, when the male voice version of the accompaniment exists, the searched target audio file is the accompaniment of the male birth version, namely, the range of the male voice accompaniment is matched with the range of the target account number.
S208, the server pushes the target audio file to the target account.
As shown in fig. 3 and 4. The target account number displays the found accompaniment file by inputting a first identifier, such as "XXXXX", into the search box shown in fig. 3. The first ranked is the target audio file, which is the accompaniment audio file that best matches the range of the target account. Fig. 3 shows audio files recommended under the accompaniment label, and fig. 4 shows audio files recommended under the sum label, including accompaniment audio files and other audio files.
When the accompaniment file is recommended to the user, the target audio file is matched according to the range of the sound range shown by the historical singing data of the user, so that the pushed audio file is more suitable for the user to sing, the similarity between the singing tone and the accompaniment tone is higher, the technical problem that the pushed audio file in the prior art is inaccurate is solved, and the technical effect of improving the accuracy of pushing the audio file is achieved.
Optionally, the obtaining, by the server, the range of the vocal range of the target account according to the historical singing data of the target account may include: acquiring a tone parameter of a target note in historical singing data, wherein the tone parameter is used for expressing the similarity between the singing tone and the tone of the note; acquiring a tone parameter average value of a target note; the range of the pitch range is determined from the mean value of the pitch parameter and the pitch parameter of each note.
The pitch parameter may be a score for each note, which may be scored using the scoring system of the singing application itself. When the similarity between the note sung by the user and the tone of the note is higher, the score of the note is higher, and when the note with the higher score is more in the song sung by the user corresponding to the target account, the overall score of the song finished sung is higher. In the embodiment, the audio data of the user needs to be analyzed, the simple audio data is not well analyzed and needs to be converted into a MIDI file, and the corresponding relation between singing score and pitch and a score model are obtained through analysis by combining a scoring system of a singing application program, and finally, the score model is matched and recommended with the range of the vocal range of the accompaniment in the accompaniment library.
The target note may be all notes in the historical singing data, or a note of a part of the historical singing data that a user sings, or a part of a climax of a piece of music or a part with difficulty in singing, that is, the target note may be all notes or a part of notes in the historical singing data, and the following description will be given by taking the target note as all notes in the historical singing data as an example.
First, a note-score relationship based on MIDI file analysis is modeled.
In the embodiment, each note in the user recording data is obtained mainly by using the MIDI file, and score data of each note is obtained by using a singing score system of a singing application. The MIDI file contains MIDI events and meta-events, and the note information is that in the meta-events, all the meta-events start with 0xFF, wherein the note information is 0x7F, so each note of the user's recorded audio can be obtained by identifying 0xFF and 0x7F, and the score of each note is inquired in the scoring system, the corresponding relationship of the singing score and the note is established, then the average score of each note is calculated through a plurality of recorded audio of the user, the average score of all notes is determined according to the average score of each note, the average score of all notes is the average value of the note parameters, and a range of the scale with higher score (for example, the score is higher than the average score of all pitches) is obtained.
The average score of each note can be obtained according to a plurality of recording audios of the user, the scores of the same note in the plurality of recording audios are weighted and averaged, and the weighted and averaged value is used as the average score of the note.
Alternatively, the server determining the range of the pitch range from the pitch parameter average and the pitch parameter of each note may include: taking the first note higher than the average value of the pitch parameter as the lower limit of the range of the pitch range according to the sequence of the pitches represented by the notes from the bass to the treble; taking a second note with the first note higher than the average value of the pitch parameter as the upper limit of the range of the pitch range according to the sequence of the pitches represented by the notes from high pitch to low pitch; the pitch represented by the consecutive notes between the lower limit and the upper limit is taken as the range of the pitch range.
As shown in fig. 5, the musical notes include C, # C, D, # D, E, F, # F, G, # G, A, # A, B, and the average scores of these musical notes in all the recorded audio of the user are 60, 70, 80, 60, 90, 70, 80, 70, 60, 20 in this order. The average score for all notes in FIG. 5 is: 67.5 points, the first tone higher than the average score is used as the lower limit (# C) from the low tone, the first tone higher than the average score is used as the upper limit (a) from the high tone to the low tone, while the ordinary user sings the music without going up the high tone or without going down the low tone, the two upper and lower limits obtained above can be simply regarded as the limits of the user without going up and without going down, the musical notes in the middle of the two boundaries can be roughly regarded as the user can perform well, so the most suitable range of the user is obtained here: the continuous notes between # C and A, and then finding the accompaniment meeting the range of the register from the accompaniment library and recommending the accompaniment to the user.
When the server determines the target audio file matching with the range of the register, the following two schemes can be adopted, including: and selecting the audio file with all the musical notes in the range of the range as a target audio file, and selecting the audio file with a certain proportion of the musical notes outside the range of the range as the target audio file.
Optionally, the server searching for the target audio file with the first identifier according to the range of the range may include: acquiring the tone highest value and the tone lowest value of a range of a register; searching for an audio file having a note with a pitch between a pitch maximum and a pitch minimum; and taking the searched audio file as a target audio file.
In the example shown in fig. 5, the register range is the consecutive notes between # C to a, and then, the audio file having the highest value of the pitch not higher than a and the lowest value of the pitch not lower than # C is searched for, resulting in the target audio file. All notes found in the target audio file in this way are in the range # C to a. Therefore, all the notes of the target audio file have pitches suitable for the user to sing, so that the target audio file recommended to the user is suitable for the user to sing, namely, when the user sings the target audio file, the similarity between each note sung and the note per se is higher.
Due to the characteristic of note change of music, some music cannot ensure that all notes are in the range of the range. That is, finding a target audio file with a first identification from a range of a register includes: acquiring the tone highest value and the tone lowest value of a range of a register; searching an audio file with the pitch being beyond the pitch highest value and the pitch lowest value and the ratio of the first note being smaller than a preset value; and taking the searched audio file as a target audio file, wherein the proportion of the searched audio file is the ratio of the number of the first musical notes to the number of all the musical notes of the searched audio file.
For example, the number of all the notes in an audio file is 200, wherein the number of the first notes not in the range of the register is 9, then the ratio is 1/20, and in the case of the preset value 1/30, the audio file with the ratio of 1/20 can be used as the target audio file. It should be noted that the preset value can be adjusted, for example, the preset value can be adjusted for different types of music.
Optionally, after the server pushes the target audio file to the target account, the method further includes: acquiring target recording data of a target account, wherein the target recording data is singing data associated with a target audio file; extracting the tone parameter of each note in the target recording data to obtain an extraction result; adjusting the range of the range according to the extraction result to obtain the adjusted range of the range; and pushing a first audio file for the target account according to the adjusted range of the.
The embodiment can adjust the range of the vocal range in real time according to the recording data of the user, and after the user sings a song, the scoring system can be used for obtaining the scoring condition of each note in the target audio file finished by the current singing, and the range of the vocal range of the user is adjusted according to the scoring condition. For example, the range of the pitch range is expanded or reduced, and the range of the pitch range is shifted to a high pitch or to a low pitch. And pushing the audio file for the target account corresponding to the user again according to the adjusted range of the range of. The pushed first audio file may be an audio file having the same or different first identification as the target audio file. For example, the target audio file is "XXXXX" for a male version of the accompaniment, and again "XXXXX" for a female version of the accompaniment may be recommended, and accompaniment of other songs may be possible. In either case, however, the recommended audio file is matched to the range of the target account.
Optionally, before the server receives the play instruction sent by the target account, the method further includes: searching at least one audio file matched with the range of the target account; and pushing at least one audio file to the target account.
After the application program is opened, before a play instruction is received, at least one audio file may be recommended to the target account, as shown in fig. 6, and a plurality of tags may be displayed on the page, for example: guessing your likes, requesting a song list, speeding up a song list, new song list and the like. A plurality of audio files can be displayed under the label guessing you like, the ranges of the audio files are matched with the range of the target account, favorite music can be quickly selected under the label guessing you like when the target account does not have a singing target, and the audio file is suitable for the user to sing, so that the application convenience and the user experience are improved.

For example, the user inputs a song title through a search box to instruct playing of an accompaniment audio file related to the song title. The accompaniment audio file of the song corresponding to the song name is the audio file with the first identification.
The acquiring unit 804 is used for acquiring the range of the vocal range of the target account according to the historical singing data of the target account;
the register range is the range of notes that fit the target account to sing. The note may represent a tone, and both the high tone and the low tone are not easy to sing, and the range of the note good at the target account may be obtained according to the historical sing data of the target account, that is, the range of the pitch range of the target account is determined.

and searching a target audio file in an audio database, wherein the target audio file is a file with a first identifier, namely an accompaniment audio file which is the same as the first identifier in the audio files searched by the target account. For example, the target account number searches for "XXXXX", and the target audio file searched for is the accompaniment audio file of "XXXXX". The range of the target audio file is matched with the range of the range, for example, the target account number is male voice, the original singing is female voice, when the male voice version of the accompaniment exists, the searched target audio file is the accompaniment of the male birth version, namely, the range of the male voice accompaniment is matched with the range of the target account number.
A first pushing unit 808, configured to push the target audio file to the target account.
As shown in fig. 3 and 4. The target account inputs the first identifier through the search box shown in fig. 3, and displays the searched accompaniment file. The first ranked is the target audio file, which is the accompaniment audio file that best matches the range of the target account. Fig. 3 shows audio files recommended under the accompaniment label, and fig. 4 shows audio files recommended under the sum label, including accompaniment audio files and other audio files.
When the accompaniment file is recommended to the user, the target audio file is matched according to the range of the sound range shown by the historical singing data of the user, so that the pushed audio file is more suitable for the user to sing, the similarity between the singing tone and the accompaniment tone is higher, the technical problem that the pushed audio file in the prior art is inaccurate is solved, and the technical effect of improving the accuracy of pushing the audio file is achieved.
When determining the target audio file matching with the range of the register, the following two schemes can be adopted, including: and selecting the audio file with all the musical notes in the range of the range as a target audio file, and selecting the audio file with a certain proportion of the musical notes outside the range of the range as the target audio file.
Optionally, the lookup unit includes: the first acquisition module is used for acquiring the tone highest value and the tone lowest value of the range of the register; the first searching module is used for searching an audio file with the tone of the musical note between the tone highest value and the tone lowest value; and the first determining module is used for taking the searched audio file as a target audio file.
Optionally, the lookup unit includes: the second acquisition module is used for acquiring the tone highest value and the tone lowest value of the range of the register; the second searching module is used for searching the audio file of which the ratio of the first note of which the tone is beyond the tone highest value and the tone lowest value is smaller than a preset value; and the second determining module is used for taking the searched audio file as a target audio file, wherein the proportion of the searched audio file is the ratio of the number of the first musical notes to the number of all the musical notes of the searched audio file.
In the example shown in fig. 5, the register range is the consecutive notes between # C to a, and then, the audio file having the highest value of the pitch not higher than a and the lowest value of the pitch not lower than # C is searched for, resulting in the target audio file. All notes found in the target audio file in this way are in the range # C to a. Therefore, all the notes of the target audio file have pitches suitable for the user to sing, so that the target audio file recommended to the user is suitable for the user to sing, namely, when the user sings the target audio file, the similarity between each note sung and the note per se is higher.
Due to the characteristic of note change of music, some music cannot ensure that all notes are in the range of the range. That is, finding a target audio file with a first identification from a range of a register includes: acquiring the tone highest value and the tone lowest value of a range of a register; searching an audio file with the pitch being beyond the pitch highest value and the pitch lowest value and the ratio of the first note being smaller than a preset value; and taking the searched audio file as a target audio file, wherein the proportion of the searched audio file is the ratio of the number of the first musical notes to the number of all the musical notes of the searched audio file.
For example, the number of all the notes in an audio file is 200, wherein the number of the first notes not in the range of the register is 9, then the ratio is 1/20, and in the case of the preset value 1/30, the audio file with the ratio of 1/20 can be used as the target audio file. It should be noted that the preset value can be adjusted, for example, the preset value can be adjusted for different types of music.
Optionally, the obtaining unit includes: the third acquisition module is used for acquiring the pitch parameter of the target note in the historical singing data, wherein the pitch parameter is used for expressing the similarity between the singing pitch and the pitch of the note; the fourth acquisition module is used for acquiring the pitch parameter average value of the target note; and the range determining module is used for determining the range of the range according to the average value of the pitch parameter and the pitch parameter of each note.

When the similarity between the note sung by the user and the tone of the note is higher, the score of the note is higher, and when the note with the higher score is more in the song sung by the user corresponding to the target account, the overall score of the song finished sung is higher. In the embodiment, the audio data of the user needs to be analyzed, the simple audio data is not well analyzed and needs to be converted into a MIDI file, and the corresponding relation between singing score and pitch and a score model are obtained through analysis by combining a scoring system of a singing application program, and finally, the score model is matched and recommended with the range of the vocal range of the accompaniment in the accompaniment library.
First, a note-score relationship based on MIDI file analysis is modeled.
In the embodiment, each note in the user recording data is obtained mainly by using the MIDI file, and score data of each note is obtained by using a singing score system of a singing application. The MIDI file contains MIDI events and meta-events, and the note information is that in the meta-events, all the meta-events start with 0xFF, wherein the note information is 0x7F, so each note of the user's recorded audio can be obtained by identifying 0xFF and 0x7F, and the score of each note is inquired in the scoring system, the corresponding relationship of the singing score and the note is established, then the average score of each note is calculated through a plurality of recorded audio of the user, the average score of all notes is determined according to the average score of each note, the average score of all notes is the average value of the note parameters, and a range of the scale with higher score (for example, the score is higher than the average score of all pitches) is obtained.
