Convert music to 528 Hz — or any Solfeggio frequency.
Whichever frequency you practice with, the conversion should be exact. HZ Detect measures each song's real tuning first, then converts it so your chosen Solfeggio anchor lands precisely on target — one song or your whole library.
All nine frequencies, plus 432.

Practitioners assign different intentions to each tone — we keep the conversion exact and leave the meaning to you. How Solfeggio maps to real music →
Measured, then converted. A "432 Hz" file that's actually 440 would land off-target in a blind converter. HZ Detect converts from the tuning it measured, so 528 means 528.
Free analysis labels every song's tuning; conversion writes lossless WAV copies, originals untouched. 5 free conversions to start — packs from $9.99.
HZP re-tunes any song to every Solfeggio frequency in real time — on web, desktop, phone, TV, even your car.
"528 Hz" uploads are as unreliable as "432" ones. Check any track free with the detector — or the dedicated 432 Hz checker.
Solfeggio conversion — common questions
Which Solfeggio frequencies can I convert to?
All of them: 396, 417, 528, 639, 741, and 852 Hz, plus the extended 174, 285, and 963 Hz — and 432 Hz as well. Each conversion maps the song so the chosen anchor lands exactly on target.
How is this different from other Solfeggio converters?
HZ Detect measures each song's real tuning first, then converts from that measured value. Converters that assume every source is 440 Hz land off target whenever the source isn't actually 440 — which, for 'Solfeggio' and '432' labeled files, is often.
Is it free?
Analyzing your library — including seeing each song's current tuning — is free and unlimited. Converting uses credits: 5 free with a new account, then packs from $9.99. Credits never expire.
Do converted files lose quality?
Converted copies are written as lossless WAV and your originals are never modified.
Can I just listen in Solfeggio without converting?
Yes — HZP re-tunes any song to every Solfeggio frequency in real time, on every device you own: web, desktop, phone, TV, even your car.
