Music Re-Tuner geliştiren: SYQEL INC

Hear your music the way you want it to sound — in real time, on the sites you already use.

Music ReTuner™ retunes whatever you're streaming on YouTube, YouTube Music, Spotify and Apple Music from standard 440 Hz to 432 Hz or any Solfeggio frequency (174–963 Hz), live, as it plays — and with one toggle, any other site with sound. No downloads, no file conversion, no extra apps.

TRY IT FREE
Install and retune your next 20 tracks free — no sign-up, no card. Then pick a plan to keep every track you stream in tune.

WHAT YOU GET
• One-click 432 Hz, plus all nine Solfeggio frequencies: 174, 285, 396, 417, 528, 639, 741, 852 and 963 Hz
• Custom A4 reference (200–700 Hz) — baroque 415 Hz, 444 Hz, 446 Hz, or anything you choose
• One license for YouTube, YouTube Music, Spotify and Apple Music — plus an optional "all other sites" mode for SoundCloud, Tidal, Deezer, Qobuz, Pandora, Bandcamp and any page with audio
• Patented retuning accuracy — built on granted patents for Solfeggio-frequency retuning
• Toolbar badge shows the current tuning at a glance
• Your tuning follows you across sites and sessions
• 100% private: audio is processed in your browser; nothing is recorded or uploaded

PRO ENGINE — INCLUDED WITH EVERY PLAN
• Pitch-perfect: shifts the pitch while the tempo stays exactly the same — no drift, video stays in sync
• Binaural beat: switch it on to give each ear a slightly different tuning around your target (1–10 Hz beat) — use headphones
• Enable it per tab with one click; the Standard engine keeps working everywhere else

HOW IT WORKS
1. Install and pin Music ReTuner
2. Open YouTube, Spotify or Apple Music and press play
3. Pick 432 Hz or a Solfeggio frequency in the popup — that's it

WHY THESE FREQUENCIES?
Standard tuning puts A at 440 Hz. Many listeners describe 432 Hz and the Solfeggio tunings as warmer, softer and more resonant — and classical players use alternative references all the time. Music ReTuner lets you hear any track the way you prefer, instead of the way it happened to be mastered.

WHO IT'S FOR
• Listeners curious about 432 Hz, 528 Hz or any Solfeggio frequency
• Meditation and yoga practitioners who want their playlists in a specific tuning
• Classical musicians and historically-informed performers exploring baroque or alternative tunings
• Creators, audiophiles and sound explorers who want control over how music resonates

INCLUDED WITH EVERY PLAN

• 7-day money-back guarantee — cancel any time
