What is a spectrogram image?

A spectrogram is a visual way of representing the signal strength, or “loudness”, of a signal over time at various frequencies present in a particular waveform. Not only can one see whether there is more or less energy at, for example, 2 Hz vs 10 Hz, but one can also see how energy levels vary over time.

How does spectrum relate to spectrogram?

A spectrogram gives a running display of a sound signal as it occurs in real time; a spectrum, on the other hand, gives us a snapshot of the sound at a specific point in time. A spectrum can enable you to see, for example, the energy distribution over the different frequencies of a single vowel, like [i].
