Show HN: A browser based binaural beats generator (decimal.fm)

This is a side project I've been working on for a week or so - a PWA that generates binaural beats entirely in the browser.

I've been using binaural beats to help with sleep for over a year now, and have found them effective for concentration too - but the existing apps trend towards ad laden bloatware, with crappy UX.

My goal with this was to create a super fast app that I love using, free from the burdens of ad ware and tracking. I built it with Astro, a sprinkling of React and Million.js - all the tones are generated client side with the Web Audio API, using a Media Session to allow for lock screen controls.

It's just a toy really, scratching my own itch - but hopefully others find some use in it.
