WebA spectrogram is like a photograph or image of a signal. A spectrogram plots time in Y-axis and frequencies in X-axis. A spectrogram also conveys the signal strength using the colors – brighter the color the higher the energy of the signal. A spectrogram explains how the signal strength is distributed in every frequency found in the signal. Web1 Answer Sorted by: 3 MFCCs are not spectrograms (time-frequency), but "cepstrograms" (time-cepstrum). Comparing MFCC with spectrogram visually is not easy, and I am not sure it is very useful either. If you wish to do so, then invert the MFCC to get back a (mel) spectrogram, by doing an inverse DCT. You can probably use mfcc_to_mel for that.
