WebThe spectrogram is a 2D visual heat map where the horizontal axis represents the time of the signal and the vertical axis represents the frequency axis. What is visualized is an image where darker colours means that for a particular time point and a particular frequency, the lower in magnitude the frequency component is, the darker the colour. WebFeb 5, 2024 · You should plot the absolute value of your output from spectrogram or stft. Maybe even the log, or 10*log10 too (but I don't recall exactly, you'll have to look up the documentation).
