Spectrogram of ocean
Spectrogram of the ocean. 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. See how the gulls' calls stand out against the deep, continuous roar of the surf
