DESIGN OF DIVERSIFIED VOCAL MUSIC TEACHING SYSTEM UNDER MULTI-OBJECTIVE MANAGEMENT

Aiming at the problem that the vocal music high-frequency signal is masked by the low-frequency signal in the vocal music teaching system, a diversified vocal music teaching system under multi-objective management is designed. In the hardware part, synchronous buck conversion and synchronous dynamic storage are realized by designing power supply circuit, microprocessor and common functional modules. In the software part, considering the particularity of vocal music course, extract the characteristic parameters of vocal music signal, and identify the vocal music label to avoid the vocal music high-frequency signal being masked by low-frequency signal, so as to manage vocal music audio resources. On this basis, the software design is completed through the diversified design of five modules: basic information management, student music homework management, music practice management, online classroom management and information notification management. The function of the system is simple and safe in user operation. In terms of performance test, the average response time and throughput of the system are better than the vocal music teaching system based on Moodle platform and Web Service, and has strong application performance.
