-
All 10 Frequencies Unlocked
174, 285, 396, 417, 432, 528, 639, 741, 852, and 963 Hz — every tone of the modern extended solfeggio set, available from the first session. No per-frequency upgrades, no per-tone gating.
-
Patent-Protected Engine
Real-time pitch shifting covered by US Patent 11,836,330. The same retune technology behind every Player Plus app, with the full frequency menu turned on.
-
Lossless and Honest
No equalizer in the signal path. No compression. No psychoacoustic enhancement. Just the precise pitch shift you asked for, nothing else.
-
Cross-Platform
iOS, Android, macOS, and Windows. Buy once per platform. The full unlock works the same everywhere.
-
Bulk Library Retuning
Point the app at a folder; every track in it plays at the frequency you choose. MP3, FLAC, WAV, and most other common audio formats.
-
No Subscriptions, No Tracking
One purchase, $119.99. No ads, no listening data collection, no pushy upsells. We don't sell your data because we don't collect it.
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.

Why we built Solfeggio Frequencies Player
Solfeggio Frequencies Player is the all-in-one version of our solfeggio retuning software — every frequency in the modern extended set unlocked from the moment you install it. 174 Hz at the bottom for body work, 432 Hz as the natural-tuning everyday alternative, 528 Hz for the warm middle, 963 Hz at the top for the closing tones of long meditations, and the six other canonical solfeggio tones in between. One app. One purchase. Every frequency available.
We built it for people who already know they want the full set. If you've been working with solfeggio for a while, you know the value isn't in any one frequency — it's in having the right tone for the kind of work you're doing today. 174 Hz for the wind-down before sleep. 417 Hz for the morning writing block. 639 Hz for the dinner table. 852 Hz for focused afternoon work. The choice is the practice, and the choice requires the full set being available.
The alternative is buying the individual Player Plus apps and stacking them — which works, but at $19.99 per frequency the math adds up fast. Solfeggio Frequencies Player is the bundle: $119.99 one-time, fully unlocked, every solfeggio frequency plus 432 Hz available from the first session.
The technology underneath is the same as every Player Plus app. Real-time pitch shifting, lossless precision, no re-encoding, no equalizer in the signal path, no compression, no psychoacoustic enhancement. Original files stay untouched. Switch between frequencies with one tap. Build playlists. Set sleep timers. Listen offline.
There are no subscriptions. There are no ads. There is no listening data collection. The frequency-shifting engine is patent-protected (US Patent 11,836,330). Built and self-funded by SYQEL INC. We answer to users, not investors. Try the player free for 20 retunes; after that, $119.99 unlocks the full set permanently on your platform.
From the audience
Loved by listeners who own their music.
-
"Bought the bundle and never looked back. Having 174 Hz for nights and 528 Hz for mornings without having to manage two apps is the whole reason I switched."
-
"I work with solfeggio in my therapy practice. Having all 10 frequencies in one tool — clean tunings, no audio artifacts — saves me real time every session."
-
"Cheaper than buying three individual frequencies. Got the all-in-one and ended up using frequencies I didn't even know I needed."

FAQ
Quick questions
What is Solfeggio Frequencies Player?
Solfeggio Frequencies Player is a music player that retunes your existing audio library to any of the 10 solfeggio frequencies (174, 285, 396, 417, 432, 528, 639, 741, 852, 963 Hz) in real time, without altering the original files. It's the fully-unlocked, all-frequencies version of our solfeggio software — a single $119.99 purchase covers every frequency in the set.
How is this different from the individual Player Plus apps?
The individual Player Plus apps (174 Player Plus, 432 Player Plus, etc.) each unlock one specific frequency for $19.99. Solfeggio Frequencies Player unlocks all 10 in a single $119.99 purchase. The retune technology is identical — same patent-protected real-time pitch shifting, same lossless precision, same no-tracking policy. The only difference is whether you want one frequency or all of them.
What's included in the $119.99 unlock?
All 10 frequencies, fully unlocked. 174 Hz, 285 Hz, 396 Hz, 417 Hz, 432 Hz, 528 Hz, 639 Hz, 741 Hz, 852 Hz, and 963 Hz. No per-frequency upgrades, no extra purchases. The one-time $119.99 covers the full set on your chosen platform.
Is it a one-time purchase?
Yes — $119.99, one time, per platform. No subscriptions, no recurring fees, no ads, no listening data collection. Try it free for 20 retunes first; after that, the $119.99 unlocks the full set permanently.
What music formats does it support?
MP3, FLAC, WAV, and most other common audio formats. The retune happens in real time during playback without re-encoding the file.
The other tunings
Looking for a single frequency instead?
Each solfeggio frequency also has its own dedicated player. Pick the tuning that fits what you're after — every app uses the same patent-protected real-time engine.
