Overview

Retune the audio of any tab from 440 Hz to 432 Hz in real time. Free with a Quantic Heartz account.

Quantic Heartz plays the audio of a browser tab in 432 Hz tuning instead of the standard 440 Hz, live, while you listen. HOW IT WORKS 1. Open a tab that plays music or video. 2. Click the Quantic Heartz icon and tap the eye. 3. The tab glides down to 432 Hz and the Q in your toolbar turns gold. Tap the eye again to switch back. EXACT, NOT APPROXIMATE Every note moves down by exactly 31.77 cents (the ratio 432/440). The tempo stays the same, and the processing delay is only about 30 to 45 milliseconds. PRIVATE BY DESIGN The audio is processed on your computer and never leaves it. The extension does not read the pages you visit, keeps no browsing history. When you open it, it only tells our server its version number, so we can count how many people use it. FREE WITH YOUR ACCOUNT Sign in with Google or with your email address. Already use Quantic Heartz on your Mac? Use the same account. MORE THAN THE BROWSER Quantic Heartz for Mac retunes your music apps too: https://quanticheartz.io Both work together: while the Mac app is tuning, the extension steps aside automatically, so nothing is retuned twice. GOOD TO KNOW - While a tab is tuned, Chrome shows its usual indicator that an extension is using the tab's audio. - Chrome does not allow extensions on its own pages (chrome://) or in the Chrome Web Store. - Questions: support@quanticheartz.io
