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,...
