An audio spectrogram is a visual representation of a sound. A spectrogram is an extremely sophisticated audio analyzer that provides a very detailed and accurate image of audio. A spectrogram is a time-varying spectral representation that has a wide diversity of spectral density of any given signal with respect to time. Spectrograms, sonograms, voicegrams, and…
