A soundwave chart is a graphical representation that visually depicts sound waves. It typically consists of a waveform, showing the amplitude (loudness) of sound over time. The x-axis usually represents time, while the y-axis represents the intensity or amplitude of the sound at any given moment. Soundwave charts are commonly used in audio editing software, music production, and scientific analysis to visualize and analyze audio signals, enabling users to identify patterns, frequencies, and changes in sound characteristics.
