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.

Free to start — re-tune your first 20 songs on us · Loved by 25,000+ listeners · iPhone · Android · Mac · Windows · TV · Web

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.”
🎧 Daniel P. — Music Producer
“HZP helps me align my meditation playlists with the intention of each session. 528 Hz feels like sunshine. I use it daily.”
🌿 Maya S. — Energy Practitioner
“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.”
🔍 Eli R. — Skeptic Turned Believer

Questions

You’ve got questions — we’ve got clarity

Does HZP really retune my music in real time?

Yes. HZP doesn’t just pitch-shift — it performs live frequency recalibration while preserving full sound quality. You’ll hear smoother tonality and a more natural feel, instantly.

Is HZP free to try?

Yes — HZP is free to start, no card required. Re-tune up to 20 of your own songs on us (they stay re-tunable forever), and listening at 440 Hz is always free. When you want unlimited re-tuning, upgrade to Core, Re:tune or Amplify anytime.

Can professionals or studios use HZP?

Definitely. Many sound therapists, DJs and engineers already use HZP to explore natural tunings. The same clarity that suits meditation music works across every genre — even EDM and film scoring.

Will it work on my devices?

Yes. HZP runs on iOS, Android, macOS, Windows, Android TV, Fire TV and any web browser — and the desktop apps can cast to your TV. One subscription works across all your devices.

Can I use HZP with streaming services like Apple Music or Audius?

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 tuning. Each one is traditionally associated with a different feeling — explore freely.
