A complete audio-reactive visualizer for psytrance music featuring: Audio Analysis (DSPEngine): - FFT spectrum analysis via Accelerate/vDSP - 64-band Mel spectrogram - Sub-bass energy extraction (<100Hz) - Automatic sidechain pump detection - Harmonic-to-Noise ratio (HNR) calculation - Peak/transient detection 8 Visualization Modes (Metal Shaders): 1. FFT Classic - Frequency spectrum bars with glow 2. Mel Spectrogram - Waterfall display 3. Sub-Bass - Pulsating rings 4. Sidechain Pump - Breathing zoom effect 5. Harmonic/Noise - Geometric vs chaotic particles 6. Mandelbrot - Audio-reactive fractal zoom 7. Tunnel Warp - Infinite tunnel with distortion 8. DMT Geometry - Sacred geometry patterns Features: - Selectable audio input device (BlackHole support) - Configurable buffer size (512/1024) - Reactivity slider for visual intensity - Auto-hiding control panel - Fullscreen support with keyboard shortcuts (1-8, F, ESC) - Persistent settings via UserDefaults - Psytrance-inspired neon/UV color palette
