Key Features:

  • Real-time FFT analysis
  • Adjustable FFT size (512-8192)
  • Spectrogram waterfall display
  • Peak frequency detection
  • Microphone or test tone input

Use Cases:

  • Analyze room acoustics
  • Identify feedback frequencies
  • Measure speaker response
  • Debug audio equipment
  • Educational demonstrations
