Honest About Claims
You will hear a lot of strong claims about 528 Hz online. We make a small one: some music sounds noticeably better at 528 Hz, and you should get to decide for yourself.
How it works
Real-time retuning. No re-encoding. No quality loss.
We don't make copies of your songs. We don't apply equalization or compression. We shift the pitch of the audio stream as it plays — and that's the entire trick.

- 03
A/B as you go
Switch back to 440 Hz any time. Compare the same song side-by-side and decide for yourself. Set a sleep timer, build playlists, listen offline.
Why we built 528 Player Plus
528 Hz is the most-discussed tone in the solfeggio set — the *Mi* of the medieval Italian musical scale, traditionally associated with the solar plexus chakra and known throughout modern sound healing as the "love frequency" or the "miracle tone." It's the frequency you've heard about even if you don't know the others — the one with the largest audience, the most associations, and the longest cultural reach. People come to 528 Hz from many directions: meditation, sleep work, sound healing practice, simple curiosity about the cultural conversation around it.
We built 528 Player Plus because the people who care about 528 Hz care a great deal — and the existing tools weren't worth their attention. Most apps either re-encoded every track (slow, lossy, two copies of every song), or supported only a couple of frequencies, or buried the option behind a subscription. None of them let you press play on a song you already love, set 528 Hz, and just listen.
So that's what we made. Point the app at your library — MP3, FLAC, WAV, whatever you've collected — and any track plays at 528 Hz, in real time, without altering the original file. Switch back to 440 with one tap and compare. Bulk-add an album. Set a sleep timer. Listen offline.
The retune is patent-protected (US 11,836,330), real-time, and lossless. There is no equalizer in the signal path, no compression, no psychoacoustic enhancement — only the pitch shift you asked for.

528 Player Plus is built and self-funded by SYQEL INC. We're a small team that prioritizes users over investors. The frequency-shifting engine is patent-protected so this option can't be quietly revoked. Whatever you bring to 528 Hz, we just give you the tool.

FAQ
Quick questions
What is the 528 Hz frequency?
528 Hz is the third tone of the canonical solfeggio hexachord — the *Mi* of the medieval Italian scale, traditionally associated with the solar plexus chakra. In modern sound healing it's known as the "love frequency" or "miracle tone" and is the most widely-recognized of the solfeggio set, with mentions across centuries of music theory, numerology, and sacred geometry. In musical terms, 528 Hz corresponds to the note C5 when the standard scale is anchored there, with A4 ending up at approximately 444.04 Hz.
What does 528 Hz do?
In the solfeggio tradition, 528 Hz is the "love frequency" — paired with solar-plexus and heart work, meditation, and intentional listening. Whether you experience anything specific is your own to discover. Technically, 528 Player Plus retunes your music in real time so the note C5 sits at 528 Hz, with A4 landing at approximately 444.04 Hz, without altering the original files.
Does 528 Hz really repair DNA?
We don't make claims about what 528 Hz can or can't do at the cellular level — that's outside what a music player should be telling you. The "DNA repair" association is a popular cultural reference around 528 Hz, originating in late-20th-century sound healing literature, but we don't endorse or rely on it. What we make is a tool. 528 Player Plus retunes your music to 528 Hz in real time, with absolute audio precision, so you can listen the way you want to. Whatever you bring to the listening — meditation, intention, simple curiosity — is yours to bring.
Is 528 Hz dangerous?
No. 528 Hz is just a musical pitch — the same way A4 = 440 Hz is. There's nothing inherently risky about listening to music tuned to 528 Hz, and we're not aware of any reports of harm from doing so. As with any audio listening, mind your overall volume and take breaks if you wear headphones for long sessions.
How is 528 Hz different from 432 Hz?
432 Hz is a small shift down from the standard 440 Hz tuning, often used as a general-purpose alternative reference for everyday listening. 528 Hz is a more specific tool, anchored at C5 with A4 ending up around 444.04 Hz, traditionally used in the solfeggio tradition for heart and solar-plexus work. Many people use 432 Hz as their default and reach for 528 Hz during specific intentional sessions.
