How do I listen to Spotify in 432Hz?

Install the 432Hz browser extension, open Spotify in Chrome, Edge or Brave, and click the frequency button on the player to choose 432Hz. The song is retuned instantly, with no download or file conversion.

Does the extension slow down the music?

Only in Speed mode, the default, by about 1.8% at 432Hz, because pitch and tempo move together like a record. Switch to Pitch mode in Chrome, Edge or Brave to keep the tempo exact while only the pitch changes.

Is the 432Hz browser extension free?

Yes. 432Hz and 440Hz are free with no account and no time limit, and 528Hz is free with an account. Pro adds Solfeggio tones, custom frequencies from 55 to 1760Hz, the Studio engine and the full Audio Lab.

Does it record or upload my audio?

No. The extension retunes audio inside your browser and never records, stores or uploads it. It does collect usage analytics and, unless you turn it off, listening stats such as which tuning you used; our privacy policy lists exactly what.

Does it work on every website?

Almost every site: it works wherever HTML5 audio or video plays. Some DRM-protected or canvas-based players give Speed mode nothing to adjust; Pitch mode in Chrome, Edge or Brave retunes the whole tab's sound instead.

Does it work on Android or Firefox?

On Android, yes, in Lemur Browser, which installs Chrome Web Store extensions; Chrome for Android cannot. Our Android guide shows the steps. There is no Firefox version on Firefox Add-ons; use Chrome, Edge or Brave on a computer, or Lemur on Android.

What is Studio sound?

Studio is the extension's highest-quality pitch engine, based on Signalsmith Stretch, and it keeps the tempo exact. It comes with Pro and is the same engine as in the 432hz.live web player.

Free vs ProWhat is free in 432Hz Browser Extension and what Pro adds

Step-by-step guides for each music service

How to use the extension on each service, on a computer and on Android:

What makes it different

Two methods, clearly labelled
Speed is light and works on any HTML5 player; at 432Hz the music plays about 1.8% slower, like a record. Speed is the default. Pitch (Chrome, Edge and Brave) captures the tab and shifts only the pitch, so the tempo stays exact. You choose, and we tell you which is which.
The Studio engine
Pro includes Studio, our highest-quality pitch engine based on Signalsmith Stretch. It is the same engine used in the 432hz.live web player, and it keeps the tempo exact.
A frequency button on the player
On Spotify, YouTube, YouTube Music and SoundCloud, a small 432 button appears right on the player (on a computer, or on Android in Desktop site mode), so you do not have to open the toolbar. On other sites, tune from the extension's toolbar icon.
One tab at 432, another at 528
Pin any tab to its own frequency. A playlist can run in 432Hz while a video in another tab stays at 440Hz.
A full Audio Lab
Volume boost and stereo pan are free with an account. Pro adds an equalizer with 10, 20 or 30 bands, delay, mono, reverse and a fine pitch slider (Chrome, Edge and Brave).

How it works

Step 1
Add it to your browser
Install Ultimate 432Hz Converter from the Chrome Web Store. It is built for Chrome and also works in Edge and Brave.
Step 2
Play your music
Open Spotify, YouTube, Apple Music or any site that plays audio.
Step 3
Pick 432Hz
Click the frequency button on the player or in the toolbar. The tab is retuned instantly.
