Hear Your Music in 432Hz, On Every Device

432Hz means tuning music so the note A vibrates at 432Hz instead of the modern 440Hz standard, slightly lower, by under a third of a semitone. It's sometimes called "Verdi tuning." Many listeners describe it as warmer and more relaxing, though the difference is subtle.

Yes. With the 432 Player browser extension you can pitch-shift Spotify, YouTube, Apple Music, Tidal and Deezer to 432Hz in real time, with no file conversion or downloading. On your phone, the 432 Player app retunes your own library and 30,000+ radio stations, and the Android guide shows how to run the extension for streaming sites.

Just open 432 Player and pick a frequency. It retunes the audio live as it plays, so you never download, re-encode or change your original files.

440Hz is the international concert-pitch standard adopted in 1939 and later set by the ISO. 432Hz is a slightly lower alternative tuning. The audible difference is small, and which one sounds better is a matter of personal preference.

No. 432Hz is a tuning choice, not a biologically special frequency. A few small studies report effects like reduced stress, but the evidence isn't robust and there's no proof it's medically superior to 440Hz. Many people simply find it more pleasant to listen to.

The Solfeggio frequencies are a set of tones (396, 417, 528, 639, 741, 852 and 963Hz) popularly associated in the sound-healing community with themes like change, connection and intuition. These associations are traditional beliefs rather than scientific fact.

528Hz is a Solfeggio tone many associate with transformation and harmony. Claims that it "repairs DNA" are not supported by scientific evidence, but plenty of listeners enjoy it. 432 Player lets you switch to 528Hz anytime.

No. 432 Player pitch-shifts the audio in real time without re-encoding or modifying the original file, so there's no added quality loss.

432 Player has dedicated apps for Android and iPhone, a browser extension for Chrome, Brave and Edge, and a web player that runs in any browser with no install.

Yes, you can start listening in 432Hz for free across the apps, extension and web player. Optional upgrades add extras like ad-free listening and an advanced equalizer.

CymaScope is our cymatics app that makes sound visible, turning audio frequencies into geometric patterns. It's based on cymatics, the science of visualizing sound, and works across a wide range of frequencies.
