Spectrogram of thunder
Spectrogram of thunder. Spectrograms are graphs that visualize sounds. The brightness of the colors shows sounds’ amplitude (loudness) across different frequencies (pitches), shown from bottom to top, and over time, from left to right. This spectrogram shows the deep, loud rumble of thunder gradually trailing off over time.
