GUI-Based Audio Player with Spectrum Analysis and Real-Time Equalization

A MATLAB GUI-based audio player implementation delivers multiple advanced features including spectrum visualization, real-time frequency equalization, playback progress control, and synchronized lyrics display. This audio player features an intuitive user interface that enables convenient control and adjustment of various audio playback parameters. Users can observe audio frequency spectra through FFT-based analysis algorithms and perform real-time equalization using digital filter implementations (such as IIR or FIR filters) to enhance audio quality. The player incorporates a draggable progress bar component that allows users to adjust playback position dynamically through callback functions handling slider events. Additionally, for enhanced music comprehension, the player implements lyrics synchronization using timestamp parsing and text rendering algorithms, enabling simultaneous audio playback and lyric display for improved musical immersion. The implementation leverages MATLAB's audio processing toolbox for signal handling and GUIDE/app designer for interface development, providing users with comprehensive music control and enriched listening experience.
