BLOKS Fundamentals FFT Spectrum Analysis Explained Understanding how sound becomes usable frequency data for audio-reactive shaders, music visualizers, and real-time audiovisual systems. FFT spectrum analysis is one of the core technologies behind modern audio-reactive visuals. It allows software to break sound into frequency bands so shaders, visualizers, and interactive systems can respond to bass, mids, […]
BLOKS Fundamentals What Is GLSL? Understanding the language that powers modern shaders, procedural graphics, real-time visuals, and GPU-driven art. GLSL, or OpenGL Shading Language, is one of the most important technologies in modern computer graphics. It allows developers and digital artists to write programs that run directly on the GPU, enabling real-time rendering, procedural graphics, […]
BLOKS History The History of Audio Visualizers From cymatics and oscilloscopes to MilkDrop, GLSL shaders, WebGL, and modern real-time audiovisual systems. Long before modern GLSL shaders, WebGL experiments, and real-time GPU graphics, people were already fascinated by the idea of turning sound into visuals. Audio visualization evolved alongside music technology, analog electronics, computer animation, and […]
