Embodiment 1

[0043] Such as Figure 1-Figure 7 A kind of multi-instrument practice comprehensive auxiliary corrector based on MATLAB is shown, embodiment discloses a kind of multi-musical instrument practice comprehensive auxiliary corrector based on MATLAB, comprising housing, radio, memory, display screen, MATLAB Processing system, the inside of the housing is provided with a memory and a MATLAB processing system, and the outer surface of the housing is provided with a radio and a display screen; the radio, memory, and display are all connected to the MATLAB processing system; The MATLAB processing system includes a sound frequency amplitude analysis module, a collection information comparison calculation module, and an information comparison result feedback module. The device is a microphone, and the storage is a mobile hard disk.

[0044] The mobile hard disk is used as the memory of the corrector, and its storage capacity can meet the needs of saving a large number of audio files, vi...

Embodiment 2

[0063] The present invention also discloses a MATLAB-based comprehensive auxiliary correction system for various musical instrument exercises, using the MATLAB-based comprehensive auxiliary corrector for various musical instrument exercises in Embodiment 1 and Embodiment 2, wherein the auxiliary correction method is as follows: MATLAB processing system Perform data conversion on the sound collected by the radio, compare it with the data in the memory, and display the processed data on the display.

[0064] Specific steps are as follows:

[0065] The first step, the frequency range of the microphone radio is: f1~f2, to collect the sound within the sound range of the instrument;

[0066] In the second step, the sound signal S collected by the microphone is transmitted to the MATTLAB sound analysis system and converted into a digital signal Sd, which is a comprehensive signal including frequency, intensity, amplitude and decibel;

[0067] According to the set beat speed Sp (Spee...

Embodiment 3

[0084] Set violin grade 6 practitioner A who wants to pass this corrector to prepare for the Central Conservatory of Music's musical instrument grade exam and prepare for etude 2 practice

[0085] At the beginning of the first practice, A selects the violin as the musical instrument to play on the initial interface, and selects the grade test in the grade test and hobbies options.

[0086] After selecting the level examination, select "Central Conservatory of Music" in the institution, select "Level 6" in the practice level, and enter the selection interface of the institution's level after completing the options.

[0087] On the music selection interface of the organization’s level, select the second etude, and set the tempo to 90 before starting.

[0088] When A selects the practice track, the display screen will send the command to the music library in the memory and call the sound source of the practice song 2, analyze the data and the score. Since the default tempo of da...

Abstract

The invention discloses an MATLAB-based multiple musical instrument exercise integrated auxiliary corrector, which comprises a receiver, a memory, a display screen and an MATLAB processing system. Thereceiver, the memory and the display screen are all connected to the MATLAB processing system. The MATLAB processing system comprises a sound frequency and amplitude analysis module, an acquisition information comparison calculation module and an information comparison result feedback module. The patent is developed and designed based on the MATLAB system. Through analysis and research of the most essential acoustical signals of musical instruments, precise analysis results and guidance suggestions are provided for practitioners, and exercise guidance can be provided for most of musical instruments. Thus, the problem that the minority of musical instruments lack exercise assistance is solved. In addition, exercise guidance of multiple items such as beat, tone, intensity, etc. is providedfor practitioners.

Description

technical field [0001] The invention belongs to various sound collection methods and audio frequency separation and analysis methods, belongs to the field of electronic information and signal analysis, and specifically relates to a comprehensive auxiliary corrector for various musical instrument exercises based on MATLAB. Background technique [0002] Nowadays, more and more people choose to learn musical instruments, and the range of musical instruments they choose is getting wider and wider. However, most of the existing musical instrument practice aids on the market provide assistance for a certain type or a certain type of musical instruments, while small types of musical instruments rarely provide practice guidance. In the prior art, AR equipment is used for image analysis to provide corrective guidance for practitioners who practice a certain type of musical instrument, but the equipment is expensive and can only perform image analysis on commonly used musical instrume...
