Web26 gen 2024 · A spectrogram is a figure which represents the spectrum of frequencies of a recorded audio over time. This means that as we get brighter in color in the figure, the sound is heavily concentrated around those specific frequencies, and as we get darker in color, the sound is close to empty/dead sound.
