sound spectrography

Sound spectrography is a technique that visualizes the characteristics of sound waves. It displays how the different frequencies (or pitches) of a sound change over time, using a graph called a spectrogram. The vertical axis shows frequency, the horizontal axis shows time, and the color or darkness indicates the loudness at each frequency. This tool helps analyze complex sounds like speech, music, or animal calls by revealing their detailed frequency patterns, making it easier to study and understand the structure and composition of various sounds.
