Practical MATLAB-Based WAV Music Player Design

This article presents a practical MATLAB-designed WAV music player that offers comprehensive audio playback functionality. The player employs MATLAB's audio processing toolbox to handle core operations, including audio file reading using audioread() function, real-time playback through sound() or audioplayer() objects, and buffer management for seamless operation. Beyond basic WAV playback, the system incorporates advanced features such as pause/resume functionality implemented via playback state tracking, stop functionality with memory reset, playlist management using array structures for sequential file handling, and loop playback through conditional repetition algorithms.

The player demonstrates format versatility by leveraging MATLAB's audio system optimization to support additional formats like MP3, FLAC, and WMA through format detection and appropriate decoder selection. Users can utilize this tool not only for playing favorite songs but also for audio editing operations including waveform analysis, volume adjustment using gain control algorithms, and basic filtering operations. The intuitive GUI interface, built using MATLAB's App Designer or GUIDE framework, ensures accessibility for both casual users and audio professionals, featuring visual progress bars, spectrum analyzers, and customizable control panels.

Implementation highlights include efficient memory management through frame-based processing for large files, event-driven controls for responsive interaction, and error handling mechanisms for invalid file formats. This WAV music player represents a robust, feature-rich tool that combines MATLAB's computational power with user-friendly design, significantly enhancing music enjoyment and audio processing capabilities.
