Your music. Your frequency. Your Choice.
Most music isn’t tuned the way you’d choose.
Almost everything you stream is locked to 440 Hz. HZP puts that choice back in your hands — instantly re-tune any song, from Apple Music, Audius or your own library, to true 432 Hz or any Solfeggio frequency. Hear it, feel it, and decide for yourself.

From the community
People hear the difference
“As someone who’s mixed audio for 15 years, I didn’t believe in the 432 Hz hype… until I ran my own tracks through HZP. The clarity blew me away.”
“HZP helps me align my meditation playlists with the intention of each session. 528 Hz feels like sunshine. I use it daily.”
“I only downloaded it to prove my friend wrong. Within minutes, I realized how tight 440 sounds compared to 432. I’ve retuned everything since.”
“No spiritual background, no engineering knowledge — just music that suddenly feels human again.”

Absolutely. HZP integrates with both Apple Music and Audius, plus any local files you own. Connect your source and hit play — HZP handles the rest automatically.
Is there any science behind 432 Hz or the Solfeggio frequencies?
Interpretations vary. Research in acoustics and psychoacoustics shows that tuning affects how we perceive sound, and many listeners describe 432 Hz as feeling warmer and easier on the ear. We share these as perceptions and tradition, not medical fact — the best test is your own ears.
Will my songs sound weird or distorted after retuning?
Not at all. HZP’s algorithm preserves pitch accuracy and tone quality — your favourite tracks sound more balanced, not “edited.”
Can I switch frequencies anytime?
Instantly. Use HZP’s real-time frequency control to move between 432 Hz, 528 Hz, 396 Hz or any Solfeggio tone. Each one is traditionally associated with a different feeling — explore freely.
