Everything you might want to know about 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.

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.

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.

If you want to retune streamed music from Spotify, Apple Music, YouTube Music, or anything else playing on your device, take a look at retunerpro.com. ReTuner Pro retunes everything coming out of your device system-wide, including streaming apps.
