Tuning clarity, no guesswork

Know the real frequency tuning of any music track.

HZ Detect measures actual tuning so you can verify 432, 440, or any Solfeggio frequency target. Platforms do not validate uploads, so labels are often wrong. Detect first, then retune your own music for guaranteed accuracy.

The core problem

Uploads are labeled by users, not validated by platforms.

People upload "432 Hz" or "Solfeggio" tracks with no verification. Leaving you guessing unless you measure the tuning yourself. HZ Detect solves this by analyzing the real frequency so you can confirm the truth before you listen or retune.

Validate a track
What to do next

Detect first, retune for certainty.

If the result is not your target, retune your own file. That is the only guaranteed way to listen at 432 Hz or any Solfeggio frequency.
