✨ Features

• Neon Aesthetic: Mirrored, centered frequency bars with soft glow effects and a reactive background that pulses with the bass.
• Beat Explosions: Dynamic particle bursts that trigger on every major beat for high-impact visuals.
• Beat-Reactive Colors: The entire color palette shifts significantly on beats, keeping the experience fresh and energetic.
• Circular Mode: Use the --circular flag for a radially expanding visualization centered on the screen.
• Musically Accurate: Uses Mel-Spectrogram analysis to map frequencies to a human-perceivable scale, ensuring the visuals "feel" right.
• Fluid Motion: Implements Temporal Smoothing (exponential decay) for professional, non-flickering bar movement.
• High Performance: Pre-calculated audio analysis and headless Pygame rendering for fast video encoding.
• Professional Layout: Left-aligned titles and optional artist subtitles for a clean, modern look.
