Tuner

A tuner that runs in a browser tab.

Real-time pitch detection through your microphone — standard and alternate guitar tunings, an adjustable A4 reference, and a needle that tells you how many cents flat you are. Nothing to install.

WIP The piano side works but isn't finished — stretch tuning and the keyboard are still being sorted out.

Svelte and the Web Audio API. Runs in the browser.
