You’re No Longer Stuck in 440 Hz.
You can now retune any YouTube song on iPhone & Mac — instantly.
For decades, 440 Hz has been the global default tuning standard.
Not because it’s proven to be better.
Not because it’s more natural.
Simply because it became the accepted reference pitch.
And if you listened to music on an iPhone or through Safari?
You had no choice.
Until now.
You Can Now Retune Any YouTube Song on iPhone & Mac
We’re excited to officially announce:
The YouTube Music Re-Tuner is now available for Safari on Mac and iPhone.
That means you can retune any song on:
YouTube
YouTube Music
Through a Safari browser.
In real time.
With one click.
No special tracks required.
No “432 Hz versions” to hunt down.
No guesswork.
Just open Safari, play your favorite song, and choose your frequency.
Why This Matters
Most music online is tuned to 440 Hz.
Even videos labeled “432 Hz” or “528 Hz” across YouTube have been proven to be mislabeled.
The only guaranteed way to ensure the music you love is tuned to the frequency you want…
Is to retune it yourself.
That’s exactly what the YouTube Music Re-Tuner does.
It changes the tuning of the audio stream in real time — instantly shifting the entire song from 440 Hz to your selected frequency.
For the first time ever, you’re in total control.
Available Frequencies
You can instantly retune 440 Hz music to powerful Solfeggio and alternative reference tunings such as:
432 Hz – Often described as warmer and more natural
528 Hz – Associated with emotional reset and clarity
639 Hz – Linked to harmony and connection
963 Hz – Often described as uplifting and expansive
Or any other Solfeggio frequency inside the extension.
Switch between them live.
Compare back-to-back.
Hear the difference for yourself.
