How to Use
• Click "🎤 Record from mic" to visualize sound from your microphone in real-time, or "🎵 Play audio file" to upload and analyze an audio file from your device • The spectrogram displays frequencies over time - time flows right to left (newest audio on right), frequency from low (bottom) to high (top), with brightness showing loudness • Use "⏹ Stop" button to end recording or playback • Adjust settings in the right panel: - Sensitivity: controls volume/audio detection level - Contrast: applies scaling to make patterns more visible - Zoom: magnifies the time axis view - Min/Max frequency: sets which frequency range to display - Frequency scale: choose Linear (even spacing) or Mel (natural weighting toward lower frequencies) - Color: change the color scheme • The display shows separate spectrograms for left and right audio channels • Grant microphone permission when prompted to use microphone recording
