Spectrogram

A spectrogram is a visual representation of sound that shows how its frequency content changes over time. Imagine it as a heat map where the horizontal axis represents time, the vertical axis shows different pitches, and the brightness or color indicates the loudness of those pitches at each moment. It helps us see details like speech, music, or animal sounds, revealing patterns that aren't obvious just listening. Spectrograms are commonly used in audio analysis, research, and engineering to better understand and interpret complex sounds.
