As opposed to our friend the Waveform, which is a graphic representation of modulation over time, the Spectrograph is a graphic representation of the relative volume of your audios frequencies over time. Paired with the waveform, and good studio monitors, you get perfect picture of all sorts of things. If you look at this screenshot you’ll see what it looks like. On the right is the scale of frequencies from0 Hertz (Hz) (Lower frequencies) to 20,000Hz (20k), The actual graph is color coded from black to purple to red to orange to Yellow. (And shades in between) The brighter the color, or the closer to yellow, the louder the frequency. You’re actually looking at a spectrographic voice print.
