432Hz Audio Converter

Retune browser audio to 432Hz, 528Hz and custom frequencies in real time. Local processing, no recording.

🎵 Retune the audio in your browser in real time. 432Hz Audio Converter lets you try 432Hz, 440Hz, 528Hz, Solfeggio-inspired presets, and custom frequencies while music or video plays in the current tab. Use it with YouTube, Spotify Web Player, Apple Music, TIDAL, SoundCloud, Deezer, podcasts, ambient streams, online lessons, and other sites that play audio. ✨ CORE FEATURES • Tune one tab without changing the sound in other tabs • 432Hz and 440Hz available for a fast A/B comparison • 528Hz, Solfeggio-inspired presets, and a custom 55Hz–1760Hz range • Pitch-perfect mode for changing tuning while keeping tempo natural • Low-latency mode when you prefer faster response • Gain, stereo pan, mono output, and a lightweight graphic EQ • Popup, Chrome Side Panel, and a small in-player tuner on supported music sites • Keyboard shortcuts and right-click menu commands • Recent tabs, favorites, simple playlists, and local JSON backup • English, Simplified Chinese, Traditional Chinese, Spanish, Japanese, and Korean UI 🔒 LOCAL-FIRST PRIVACY The audio conversion graph runs inside Chrome. The extension does not record, store, or upload your tab audio. Settings, recent tabs, favorites, and playlists stay in local extension storage unless you explicitly export them. Search shortcuts open the music services you choose; the extension does not need your music-service password. 🎚️ A QUIET, PRACTICAL WORKFLOW Install the extension, open a music tab, click the toolbar button, choose a target frequency, and press Tune. Compare 440Hz and 432Hz, try a different preset, or enter a custom value. Restore standard tuning at any time. The core workflow does not require a card, a trial timer, or an account. 🧪 LISTEN AND DECIDE FOR YOURSELF People use tuning tools for music practice, meditation playlists, ambient sound, vocal exercises, focus sessions, and simply comparing how a track feels at different references. This extension makes the experiment quick and reversible without making medical or therapeutic claims. ⚙️ SETTINGS THAT STAY OUT OF THE WAY Choose a default frequency, conversion mode, gain, pan, mono output, EQ profile, theme, language, and blocked sites. Export a JSON backup when you want to move your preferences to another Chrome profile. Advanced subscription infrastructure is kept ready for future features, but the current launch experience is designed to feel free and complete. Support: hello@reforgeextensions.com
