The whole process is pure front-end animation. AnalyserNode based on the Web Audio API obtains audio spectrum data and uses Canvas to draw various visualization effects. Supports multiple modes and color schemes.
Ideal for music player decoration, party atmosphere, or purely visual effects to appreciate sound. The implementation principle is Fast Fourier Transform (FFT) and Canvas Mapping.
