Detailed Description
In the embodiment of the application, audio data are collected in the process of playing a music score; identifying the collected audio data to obtain corresponding music score symbols; based on the obtained score symbol, detecting whether to perform one line of score in the currently displayed score to obtain a detection result; when the detection result represents that one line of music score is performed, one line of music score which is currently performed is not displayed.
So that the manner in which the features and aspects of the embodiments of the present application can be understood in more detail, a more particular description of the application, briefly summarized below, may be had by reference to the appended drawings, which are merely illustrative, and not intended to be limiting of the application.
As shown in fig. 1, a processing method of a music score according to an embodiment of the present application is described in detail, and the method is applied to a client, and includes the following steps:
step 101: collecting audio data during the process of a music score being performed; the musical score may be displayed on a currently displayed page of an electronic ink screen of the client.
Wherein the score is an electronic score, which is a music score for singing or playing, such as a staff, a numbered musical notation, etc. Here, the musical score may be displayed in pages using an electronic ink screen, and a plurality of lines of musical scores may be displayed in a current display page. Wherein the electronic ink screen is a screen using electronic ink.
In practical application, the audio data can be collected through a microphone installed on the client. The audio data may be audio data transmitted from a user collecting musical instruments while performing a score using the musical instruments; the audio data sent by the user can be collected when the user sings according to the music score.
Step 102: and carrying out recognition processing on the collected audio data to obtain corresponding music score symbols.
Wherein, the music notation is a common notation in the music score, namely a music notation, and the music notation is a recorded tone with different lengths.
Here, the recognition process of the score symbol includes: preprocessing the collected audio data, such as analog-to-digital conversion processing, and extracting features of the preprocessed audio data, namely extracting fundamental tone frequency data from the preprocessed audio data; the identified score symbols are determined based on the extracted pitch frequency data using a preset recognition model, such as a hidden markov model (HMM, hidden Markov Model) model. The preset recognition model is obtained through machine learning by utilizing pitch frequency sample data.
Step 103: based on the obtained score symbol, whether to perform one line of the currently displayed score is detected, and a detection result is obtained.
In order to perform a refresh process for a line of score without affecting the user's viewing of the score during performance, it is necessary to determine a line of score after performance according to the identified score symbol.
In practice, the user performs the score in conditions including, but not limited to, the following:
1. the user can perform according to the proficiency of the music score displayed by the electronic ink screen, and can perform continuously in the performance process;
2. the user may interrupt performance due to other things during performance of the score;
3. the user cannot perform the music score displayed by the electronic ink screen skillfully, and performance can be repeated in the performance process;
4. the user is a novice who has just learned the score, and may jump to perform during performance.
In an embodiment, when the user can continuously perform the score, the detecting whether the performance is completed for a line of the currently displayed score based on the obtained score symbol includes: for each currently displayed line of music score, judging whether each first music score symbol in the corresponding line of music score is identical to each second music score symbol in the obtained music score symbols; when the same, the corresponding line of the music score is taken as the line of the music score of which the current performance is completed, and the detection result of the line of the music score in the current display of which the performance is completed is obtained.
In practical application, when the user can continuously play the score, the user can preset the time for playing one line of score, so that the client can judge whether to play one line of score according to the acquired time for playing one line of score by the user. For example, assuming that the duration of a user playing a line of a score is 10 seconds, a timer is started when the acquisition of audio data emitted by the user or an instrument used by the user is started; when the timing reaches 10 seconds, the stored 10 seconds of audio data are identified, and a second music score symbol is obtained; when the timing reaches the first 10 seconds, the count is 1, and each first music score symbol in the currently displayed first line of music scores is compared with each identified second music score symbol to obtain a comparison result; when the comparison result indicates that each first score symbol is identical to each second score symbol, it is determined that the first line of scores has been performed.
When the user interrupts performance during performance, the detecting whether performance is completed for a line of the currently displayed score based on the obtained score symbol, comprising: judging whether a first music score symbol section is contained in the music score symbols identified based on the audio data acquired after the pause; the first music score symbol section consists of the last N first music score symbols in the music score of the corresponding line and the first M first music score symbols in the music score of the next line of the corresponding line; when the inclusion is determined, the score of the corresponding line is regarded as the score of the line where the current performance is completed. Wherein N is a positive integer greater than 1, M is a positive integer greater than 1, and the N, M value can be adjusted according to practical conditions.
Here, the process of the client determining that the user interrupts the performance includes: when no score symbol is recognized based on the audio data, the client determines that the user has occurred to interrupt performance during performance.
When the user performs repeatedly during the performance, the detecting whether the performance is completed for a line of the currently displayed score based on the obtained score symbol includes: for each currently displayed line of music score, judging whether each first music score symbol in the corresponding line of music score is the same as each third music score symbol; the third score symbol is a score symbol identified based on audio data collected after repetition; when the same, the score of the corresponding line is regarded as the score of the line where the current performance is completed.
Here, the process of the client determining the user repeating performance includes: when a music score symbol is identified, the client can compare the currently identified music score symbol with the last identified music score symbol to obtain a comparison result; when the comparison result indicates that the two score symbols are identical, it is determined that the user has repeatedly performed during the performance.
When the user performs a skip performance during the performance, the detecting whether the performance is completed for one line of the currently displayed score based on the obtained score symbol includes: determining at least one line score corresponding to each second score symbol from currently displayed scores based on each second score symbol identified by the audio data; judging whether a second music score symbol section is contained in the music score symbol identified based on the audio data; the second score symbol segment is composed of the last N score symbols of the last line of the at least one line of scores; when the inclusion is determined, it is determined that the user has occurred a skip performance during the performance.
Here, the process of determining the user skip performance by the client includes: determining the number of the line music score corresponding to the second music score symbol from the currently displayed music score based on the second music score symbol identified by the audio data; and when the number of the line music spectrums is larger than two lines, determining that the user plays in a jumping manner in the playing process.
Step 104: when the detection result represents that one line of music score is performed, one line of music score which is currently performed is not displayed.
In order to achieve a line-by-line erase of the score, when a line of score is performed, the line of score is not displayed, i.e. erased. Thus, by erasing row by row, the problem of erasing too fast and leaving miscellaneous points when erasing the whole display page can be avoided.
In order to thoroughly erase a line of currently performed music score to avoid leaving miscellaneous points, each line of the performed music score can be divided into at least two parts; and determining the erasing time of each part of the music score according to the performance time of the non-performed music score; and carrying out partial erasure processing on the corresponding part music score according to the erasure time determined by each part music score.
In one embodiment, the dividing the performed score line into at least two parts includes: dividing a line of music score after being played into at least two parts according to a staff composing the current line of music score; alternatively, a line of the score after the performance is divided into at least two parts according to the measure in the current line of the score.
For example, when a line of score after performance is made up of two sheets, the score symbol in the first sheet is taken as a first partial score and the score symbol in the second sheet is taken as a second partial score. When a line of the score after the performance is composed of four subsections, the score symbol in the first subsection is used as a first part of the score, the score symbol in the second subsection is used as a second part of the score, the score symbol in the third subsection is used as a third part of the score, and the score symbol in the fourth subsection is used as a fourth part of the score.
When a line of the music score after the performance is divided according to a staff, the line of the music score after the performance can be erased line by line; when dividing a line of the score after performance by measures, it is possible to achieve erasure of a line of the score after performance by measures. Therefore, the music score is erased line by line or the music score is erased section by section, and the problem that miscellaneous points are left on a display interface due to too fast erasing time can be avoided.
In an embodiment, the nth line of music score is a line of music score of which the current performance is completed, and the determining the erasing time of each part of music score according to the performance time of the non-performed music score includes: determining a first line number of the non-performed music score according to the number of the partial music scores divided by the Nth line music score; the difference between the first number of lines and the partial score number is 1; determining at least two lines of the first line of the music score from the non-performed music score; each line of music score in the at least two lines of music scores is separated from the Nth line of music score by a preset line number; and determining the erasing time of each part of the music score according to the time when each line of music score in the at least two lines of music scores is performed. The preset number of lines, the erasing time and the division score are required to be adjusted according to actual conditions.
Here, it is assumed that the nth line music score is divided into three parts of music scores; determining that the first line number of the non-performed score is 2; from the non-performed scores, a score of 2 lines apart from the nth line of music score, i.e., an n+2-th score, and a score of 4 lines apart from the nth line of music score, i.e., an n+4-th score, are determined; the first partial score is not displayed when the N-th row performance is completed, the second partial score is not displayed when the n+2-th row performance is completed, and the third partial score is not displayed when the n+4-th row music score performance is completed.
In an embodiment, when the nth line score is divided into two parts of score; the step of not displaying a line of score currently performed includes: not displaying part of the N-th line score; detecting whether the performance is completed on the (n+1) th line of music score; when it is determined that the n+1st line music score performance is completed, the rest of the N-th line music score is not displayed; wherein N is a positive integer greater than 1.
Here, it is assumed that the nth row of music score is composed of two sheets, and thus a score symbol in a first sheet of the nth row of music score may be taken as a first partial score and a score symbol in a second sheet as a second partial score; determining that the first line number of the non-performed score is 1; from the non-performed score, a score 1 line apart from the nth score, i.e., an n+1th score, is determined; the first partial score is not displayed when the N-th row performance is completed, and the second partial score is not displayed when the n+1-th row performance is completed.
In an embodiment, when the nth line score is divided into two parts of score; the method further comprises the steps of: when it is determined that the performance of the n+1-th line music score is completed, a part of the n+1-th line music score is not displayed; when it is determined that the n+2-th line musical score performance is completed, not displaying the remaining part of the n+1-th line musical scores, not displaying part of the n+2-th line musical scores, displaying the N-th line musical score of the first display page; the first display page is different from the current display page. The first display page is the next display page to the current display page.
Here, the process from the full display to the erasing of the part, i.e., the fade display, is required for each line of the score until the full process is erased.
In order to display the musical score content of the next display page, after one line of musical scores after being played is completely erased, the musical score content of the next display page corresponding to the current line may be displayed.
In an embodiment, the method further comprises: detecting whether rest marks meeting preset conditions exist in the obtained music score symbols or not; searching for the rest from the currently displayed score when it is determined that the rest exists; and when the rest is found, not displaying the music score of the current display page.
Wherein, the rest characters meeting the preset conditions comprise a binary rest character and a full rest character.
Here, since the probability of occurrence of the half rest and the full break in each line of the score in the current display page is small, when the half rest or the full break is detected, the whole screen refresh can be performed, that is, the score of all lines of the current display page is not displayed. Therefore, the refreshing processing of the progressive music score is not affected, the ghost can be removed through the whole screen refreshing, the user performance is facilitated, and the user performance experience is improved.
By adopting the technical scheme of the embodiment of the application, each line of music spectrum of the current page can be erased completely before the music score of the next display page is displayed, so that the miscellaneous points cannot be displayed in the next display page, and the problem that the music score performance is affected due to the fact that the miscellaneous points are left on the display page due to too high refreshing speed in full screen refreshing can be avoided.
The following describes the implementation process and principle of the present application in practical application by taking specific embodiments as examples.
