How is the program useful?

A sonogram is a spectral representation of an audio signal, where time is represented along the x-axis, frequency along the y-axis, and energy is shown as a grayscale. The sonogram is an ideal notation form for electroacoustic music, where one can easily see how different sound images are positioned in time.
