Interactive samples where the math hiding inside music becomes something you can see and hear — from the spectrum of a sound to the group theory of chords. Made to explore, take apart, and build on.
交互小样,供参考探索:声音里的数学 — 频谱、傅立叶、几何、群论、节奏数论 — 都能看得见、听得见。全部浏览器直接打开,无需登录。
Playful and immediate — a good first look at “music is math.”
Rigorous, gifted / competition level — the real mathematics, made interactive and audible.
Each sample is a single self-contained page — it runs entirely in your browser, works offline, and loads no external code. Best on a laptop or tablet; the microphone samples need permission (they also work with built-in synthesized sounds if you decline). Clean-room originals built for MyWorld; concepts credit the open-source and academic work they learn from.
