+# HTML + JavaScript instrument tuner
+---
+## What
+A simple webapp that listens to your microphone, figures out what note you are trying to play, and
+tells you if that note is in tune.
+
+## Why
+  - All the free instrument tuner apps seem to have ads
+  - Fast Fourier Transforms seemed interesting
+  - I was bored
+
+## How
+This makes use of the Web Audio API's
+[`AnalyserNode`](https://developer.mozilla.org/en-US/docs/Web/API/AnalyserNode). I figured all the
+bits and pieces out following this [MDN
+tutorial](https://developer.mozilla.org/en-US/docs/Web/API/Web_Audio_API/Visualizations_with_Web_Audio_API)
