In plain words
Interactive Essay on Signals, Sampling and the Fourier Transform is an educational resource designed to teach introductory digital signal processing concepts through interactive visualizations, animations, and sound. The text uses visual and auditory elements rather than traditional linguistic explanations to help learners understand the Discrete Fourier Transform and related topics. It serves students and practitioners studying signal processing who benefit from interactive learning methods, aiming to make complex mathematical concepts more accessible and less intimidating through hands-on exploration.

From the sources
This text is designed to accompany your study of introductory digital signal processing. 1 It’s an eccentric piece of not-so-rigorous literature with a preoccupation for explaining things using interactive visualizations, animations and sound. 2 My goal is to explain the Discrete Fourier Transform using a miniature curriculum which leverages your ability to learn concepts and absorb information visually instead of linguistically. 3 My hope is that these glyphs become slightly more comprehensible and slightly less intimidating after reading the subsequent 30 or so pages. 4 If you’re really serious about learning the theory and practice of digital signal processing, you should not use this…from jackschaedler.github.io

Last April I shared about my Resonate project here (https://news.ycombinator.com/item?id=43694157) A lot has happened since: the work I presented in much more detail at last June's International Computer Music Conference (ICMC) got best paper award. I also gave a talk at the Audio Developer Conference in Bristol last November, the video is on YouTube). This year's work, which I recently presented at this year's ICMC, starts with known techniques from the phase vocoder literature to build self-tuning filter banks that extract very efficiently the frequency components that are…
