What is 432Hz, and why people like it
432Hz is an alternative tuning where the note A is set to 432 vibrations per second instead of 440, the standard adopted in 1939. That is about a third of a semitone lower, often called "Verdi tuning." Many listeners find it warmer, softer and more relaxing to listen to.
Retuned live, tempo kept
432 Player lowers the pitch while the music plays. Our Android apps, web player and converters keep the beat exactly where it was, the extension offers a tempo-exact Pitch mode, and your original files are never touched.
Nothing uploaded
Live tuning and our converters both run on your own device. Your music and videos never leave it.
Trust your own ears
The 432 vs 440 difference is subtle and personal. Switch back and forth in one tap and decide for yourself.
Free to start. Pro when you want more.
432Hz is free in the Android app, the browser extension, the web player and the converters. Pro adds more tunings, the Studio pitch engine, the full equalizer and higher converter limits. One plan covers the web player, the converters and the browser extension.
The Android apps have their own Pro plans in Google Play; the iPhone app and CymaScope are one-time purchases.
Frequently asked questions
432Hz, our apps, and how they work, answered plainly.
432 Player is a family of apps that play music in 432Hz instead of the standard 440Hz. It retunes audio live as it plays, on Android, iPhone, in your browser and on 30,000+ radio stations, and it can also convert song and video files to 432Hz in your browser. The first app came out on iPhone in April 2013.
432 Player does more and has done it longer than any other 432Hz maker we know of: live playback on phone, browser, web and radio, plus converters for audio files and videos. It has been around since April 2013, has 1M+ downloads on Google Play, and is discussed in peer-reviewed research. Our Android apps, web player and converters keep the tempo exact, the extension offers a tempo-exact Pitch mode, and we say which method each product uses.
Real-time playback retunes music while it plays and leaves your files unchanged; converting writes a new 432Hz file you can keep. Use the apps, extension or web player to hear anything in 432Hz instantly, including streaming and radio. Use the 432Hz Converter or Video Converter when you want a file to keep, share or play in another app.
Drop the song into the free 432Hz Converter at 432hz.live/convert: it runs in your browser, keeps the same length and tempo, and saves a 432Hz MP3 (or a 24-bit WAV with Pro). If you only want to listen, 432 Player retunes music live with no file to convert.
Yes. The 432Hz Video Converter retunes the soundtrack of MP4, MOV, M4V, WebM and MKV files in your browser and writes a new video with the same length and the same audio-video sync. With a free verified account the picture is copied untouched, with no watermark. Your video is never uploaded.
Yes, in your browser. The 432Hz browser extension (Ultimate 432Hz Converter on the Chrome Web Store) retunes Spotify, YouTube, Apple Music, Tidal, SoundCloud, Deezer and other sites with HTML5 audio as they play, with no file conversion. Phone streaming apps do not let other apps change their sound, so on your phone the 432 Player app retunes your own music files instead.
Android phones and tablets, iPhone and iPad, and computers with Chrome, Edge or Brave. The web player and the converters run in modern browsers on computers and phones, with nothing to install. 432 Player works with Android Auto and can cast to Chromecast and DLNA speakers. The 432 Radio app also runs on Android TV and Google TV.
Yes, you can listen in 432Hz for free on Android, in the browser extension, in the web player, and in the converters with daily limits. The iPhone version of 432 Player is a one-time purchase, and CymaScope is a paid app. Optional Pro adds more tunings, the Studio pitch engine, the full equalizer, unlimited radio favorites and no ads on Android, and higher converter limits.
Since 15 April 2013, when 432 Player came out on iPhone, more than 13 years ago. A peer-reviewed 2021 article in the Journal of Popular Music Studies calls it the first smartphone app developed for 432Hz music. Its App Store page, archived by the Internet Archive in February and May 2014, already shows the app with listener reviews. The Android app followed on 30 November 2014 and is still updated several times a month.
Yes. 432 Player is discussed in a peer-reviewed article by Ruth E. Rosenberg, Associate Professor of Music at the University of Illinois Chicago: "Perfect Pitch: 432 Hz Music and the Promise of Frequency," Journal of Popular Music Studies 33(1), 2021. It describes 432 Player as the first smartphone app developed for 432Hz music and draws on several hundred user reviews and messages from the iOS and Android apps. The article studies 432Hz as a cultural movement; it does not test or endorse health claims.
Converting processes the sound, so the new file is not bit-identical to the original, but we keep the audio path careful. The 432Hz Converter decodes each file at its own sample rate to avoid an extra resampling step, works in 32-bit float and can save 24-bit WAV (Pro). The video converter copies the picture untouched (verified free account or Pro) and checks sync before download. Live playback never changes your files at all.
Yes. The Android app had about 16 new versions between mid-August and early October 2026, and the browser extension is updated frequently. Many changes start as user messages: the Android language picker was added after a review asked for Russian, and we removed a required sign-in in the extension after users told us it slowed them down. Write to us from the Feedback option in the apps, the extension's Report a bug, or our Contact page.

432Hz music is music tuned so the note A vibrates at 432Hz instead of the modern 440Hz standard, about a third of a semitone lower. It is sometimes called "Verdi tuning." Many listeners describe it as warmer and more relaxing, though the difference is subtle.
440Hz is the international concert-pitch standard adopted in 1939 and later set by the ISO; 432Hz is a slightly lower alternative. The audible difference is small, and which one sounds better is personal preference. 432 Player lets you switch between them in one tap to compare.
No. 432Hz is a tuning choice, not a biologically special frequency, and there is no robust evidence that it is medically different from 440Hz. Many people simply find it more pleasant to listen to, and that is the reason we build these apps.
The Solfeggio frequencies are a set of tones (174, 285, 396, 417, 528, 639, 741, 852 and 963Hz) that the sound-healing community associates with themes like change, connection and intuition. These associations are traditional beliefs, not scientific fact. 432 Player offers them as tunings with Pro: the full set in the web player, the extension and the converters, and 396 to 963Hz in the Android app.
528Hz is a Solfeggio tone many people associate with harmony. In 432 Player it is applied as A=444Hz, which puts the note C at about 528Hz. Claims that it "repairs DNA" are not supported by scientific evidence, but plenty of listeners enjoy it.
Play your music in 528 Hz →CymaScope is a paid app for Android and iPhone, made with the CymaScope team, that shows sound as CymaGlyph images from the CymaScope laboratory. Play a note on its keyboard or sing into the microphone and see the pattern, and compare 432Hz with 440Hz imagery.
