Built for accurate tuning, not guesses.

hzdetect exists to replace tuning myths with measurable results. We help you detect the real frequency in any track, including Solfeggio tunings, then guide you to retune your own music for guaranteed accuracy.

Platforms do not validate tuning labels. Anyone can upload a track and claim it is 432 Hz. We provide the detector and retuning tools so you can verify the truth.
