The inputs to the Spectrogram are a one-dimensional array of amplitude values and the sampling rate. They are the same inputs as the Waveform graph.

An audio spectrogram is sometimes called a sonograph, sonogram, voiceprint, or voicegram. The Spectrogram is a more detailed representation of sound than the Waveform graph. It shows a correlation between frequency and amplitude (loudness) over time, which helps visualize the frequency content in a signal. Spectrograms make it easier to identify musical elements, detect melodic patterns, recognize ...
