What do the colors mean on a spectrogram?
Colors in a Spectrogram
With spectrogram displays, colors indicate vertical displacement. Different colors represent different y-axis values. The color bar at the left side of the display indicates the color scheme used.
How do you read a spectrogram?
In the spectrogram view, the vertical axis displays frequency in Hertz, the horizontal axis represents time (just like the waveform display), and amplitude is represented by brightness. The black background is silence, while the bright orange curve is the sine wave moving up in pitch.
Which color in spectrogram is the loudest?
The amplitude (or energy or “loudness”) of a particular frequency at a particular time is represented by the third dimension, color, with dark blues corresponding to low amplitudes and brighter colors up through red corresponding to progressively stronger (or louder) amplitudes.
