About This Tool

This sound frequency analyzer captures audio from your microphone and displays a real-time frequency spectrum with spectrogram visualization and peak frequency detection. It is useful for musicians tuning instruments, audio engineers analyzing sound characteristics, and educators demonstrating acoustic principles. The tool provides detailed frequency breakdowns to help identify dominant tones, harmonics, and noise patterns.

How to Use

  1. Allow microphone access when prompted by your browser
  2. Play or produce the sound you want to analyze near your microphone
  3. Observe the real-time frequency spectrum, spectrogram, and peak detection display
  4. Identify dominant frequencies and use the data for tuning, analysis, or troubleshooting
