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 — in your browser, on your phone, and in the desktop app that analyzes and retunes entire libraries. Wherever you run it, everything analyzes on-device; your music is never uploaded.

HZ Detect is built by SYQEL INC — the team behind HZP, Music Retuner, and Retuner Pro.
