528 Player Plus

Tune your existing local songs to 528 Hz in real time. The Player Plus suite covers all 10 frequencies — 528 Hz, 432 Hz, and the eight other solfeggio frequencies — so you can pick exactly what you want.

Music is produced and performed at the universal concert pitch of 440 Hz. The Player Plus suite lets you retune away from that — to 432 Hz, to 528 Hz, or to any of the other solfeggio anchors. Your music, your choice, your library.

Try it free — 20 songs on us. Unlock unlimited 528 Hz retuning forever with a one-time purchase. No subscription. No monthly fees. No recurring charges. Ever.
