"基于Qt的音频管理系统设计与实现"

Abstract The Nokia Qt is the development of a cross-platform C++ graphical user interface application framework. It provides application developers with all the necessary functions to build artistic-level graphical user interfaces. Qt is completely object-oriented, easily extensible, and allows true component programming. This paper introduces the entire process of generating a music player from analysis to development to system design and testing, including four chapters. Chapter 1 is the introduction, briefly introducing music and audio encoding. Chapter 2 is the system functionality, expressing the basic functions required by the system with a use case diagram. Chapter 3 is the system design, detailing each function of the system based on Chapter 2. Chapter 4 is the system implementation, including screenshots of the main interface, each function interface, and code snippets. The introduction of the system development platform specifically introduces the main interface and usage methods of Qt, including the specific location and usage methods of commonly used tools, the generation of the workspace, project creation, adding and deleting files in the project, compiling the project, testing the project, etc. The later sections introduce system planning and analysis, the application's main interface, code writing and function implementation, system compilation and operation, ultimately realizing the function of a music player that can play and control song music. Keywords: Qt, player, component programming.
