🎵 Analyze Music Tuning in Real Time

HZ Detect is a professional-grade pitch analyzer that listens to your computer’s audio and instantly detects the A4 reference frequency — helping you determine whether a song is tuned to 432 Hz, 440 Hz, 444 Hz, or any custom pitch standard.

Ideal for musicians, producers, sound engineers, and frequency enthusiasts, HZ Detect brings studio-level pitch analysis right into your browser.

⚙️ How It Works

🧠 Uses advanced frequency analysis (YIN algorithm) to detect fundamental pitch in real time.

🎧 Works with any browser tab or system audio — simply select your source and press Start.
