HZ Detect

What it does

HZ Detect is a real-time tuning analyzer for musical pitch: measure A4 reference tuning and detect frequency with precision. Ideal for musicians, audio engineers, and enthusiasts.

Detect the true tuning of any track, including Solfeggio targets. Learn why uploads are mislabeled and retune your own music for guaranteed accuracy.

Streaming platforms don't validate tuning claims — anyone can label an upload "432 Hz." HZ Detect measures what's actually there. Check a track below right now, free. The desktop app does this for your entire music library — every song measured, and any song retuned from its measured tuning to your target, automatically. Point it at your music folders: free analysis labels every song's true tuning, and retuning converts the ones stuck at standard 440 — from their measured tuning to 432, 528, or any Solfeggio target. Point your phone at whatever is playing: it names the song and measures its tuning, free. iOS & Android. Detects while you stream — YouTube, or any app via desktop audio. Free…from hzdetect.com
