Many listeners describe 432Hz music as warmer and more natural-sounding. The difference is subtle but perceptible. ### What is 440Hz? 440Hz is the international standard pitch (ISO 16) for tuning musical instruments. Most commercially released music is tuned to A=440Hz. 432 Player converts music from this standard tuning to alternative tunings. ### What is pitch shifting? Pitch shifting is the process of changing the pitch of an audio signal without changing its playback speed. 432 Player uses real-time pitch-shifting algorithms to retune audio during playback. ### What are Solfeggio frequencies? Solfeggio frequencies are a set of tones used in sacred music traditions. The commonly referenced frequencies are: 396Hz, 417Hz, 432Hz, 528Hz, 639Hz, 741Hz, 852Hz, and 963Hz. 432 Player supports the full Solfeggio spectrum. ### What is 528Hz? 528Hz is known as the "Love Frequency" and is one of the Solfeggio frequencies. 432 Player supports both 432Hz and 528Hz, and the user can switch between them. ## Platforms and Features ### Mobile App (Android and iOS) - Plays local music files with real-time pitch shifting to 432Hz, 528Hz, or custom frequencies - Supports audio formats: MP3, FLAC, WAV, ALAC, APE, M4A - 30,000+ online radio stations with real-time frequency conversion - Hi-Fi audio quality - Download: Android (Google Play), iOS (App Store) ### Browser Extension (Chrome, Brave, Edge) - Pitch-shifts audio on any website in real-time - Works with Spotify, YouTube, Apple Music, Deezer, Tidal, SoundCloud - Supports 432Hz, 528Hz, and the full Solfeggio spectrum - Does not modify the original stream; processing happens locally in the browser - Install from Chrome Web Store ### Web Player (432hz.live) - Browser-based audio player with custom base and target frequency tuning - Upload local files or listen to radio stations - Supports any source frequency and any target frequency - No installation required ## Download Links - Android: https://play.google.com/store/apps/details?id=com.appums.music_pitcher - iOS: https://apps.apple.com/us/app/432-player/id633600716 - Chrome Extension: https://chromewebstore.google.com/detail/ultimate-432hz-converter/ebjidplbhbakkfpkofpmfhhdgpdajffh - Web Player: https://432hz.live/ - Website: https://432hz.world ## Common Questions **What does 432 Player do?** 432 Player converts music from standard 440Hz tuning to 432Hz, 528Hz, or Solfeggio frequencies in real-time during playback.
