{"version":"1.0","type":"rich","title":"FFT products","description":"This example demonstrates the Fourier Transform and Fast Fourier Transform algorithms applied to digital signal processing. The visualization displays the frequency spectrum output generated by these transforms, which are implemented through custom JavaScript classes including DFT, FFT, and supporting utilities for windowing and filter operations. The rendering uses WebGL and is part of a comprehensive DSP library that includes ADSR envelopes, biquad filters, and oscillators. The code calculates spectral magnitudes from time-domain buffers using precomputed sine and cosine lookup tables.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/74b90bb0267641e38fd33e601d9f231e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
