How to listen to music in 432 Hz.
Short answer
There are three ways to listen to music in 432 Hz: find recordings that were made or uploaded in 432 Hz, convert audio files you own, or retune the sound live while it plays. Live retuning is the only way that works with streaming apps and your whole library. Quantic Heartz does that on Mac and Android: it lowers the pitch by 31.77 cents, from A=440 Hz to A=432 Hz, without changing the tempo.
Three Ways
Three ways to 432 Hz. Pick by what you play.
Limited choice
A few artists record in 432 Hz, and many playlists and videos are labelled 432 Hz. Most of these are copies someone pitch-shifted, and you only get the songs they picked.
Your own files only
An audio editor such as Audacity lowers the pitch of a file by 1.818 percent and saves a copy. It works for files you own, one at a time, not for streaming.
Everything that plays
An app retunes the sound while it plays, in every app on a Mac and in the music and video apps on Android that allow audio capture. This is what Quantic Heartz does.
Devices
Mac, Android and soon iPhone.
On a Mac, Quantic Heartz retunes everything that plays: Spotify, Apple Music, YouTube, Tidal, podcasts and videos. Live calls are the exception, because macOS sends call audio straight to the hardware.
On Android 10 and later, Quantic Heartz for Android retunes the music and video apps that allow audio capture, such as the YouTube app, after a one-time setup. The iPhone app for iOS 27 is launching on the App Store.
Listening
How to hear the difference.
Start with a song you know well, ideally with headphones. Switch between 440 Hz and 432 Hz at the same moment of the song and listen to the voice and the low end.
Many people describe 432 Hz as warmer and calmer. The research so far is small and mixed, so we make no health claims: listen and decide for yourself.
