Interactive Demo - Audio Compression with the DFT

Interactive Demo - Audio Compression with the DFT

Explore how sound can be compressed with an interactive demo based on the Discrete Fourier Transform (DFT). Upload or record your own audio, watch it move into the frequency domain, remove the least important components, and listen to how the result changes.

Interactive Image Filtering with the Discrete Fourier Transform (DFT)

Interactive Image Filtering with the Discrete Fourier Transform (DFT)

Discover how images can be filtered with the Discrete Fourier Transform (DFT). Upload an image, inspect its frequency-domain representation, apply low-pass, high-pass or band-pass filters, and compare the spectrum with the resulting image.

Bezier Curves and Surfaces

Bezier Curves and Surfaces

Explore 2D and 3D Bezier curves, and a 3D Bezier surface, by moving control points and visualizing De Casteljau's algorithm.
