WebAug 7, 2015 · After windowing, an FFT is calculated per frame. The output of these FFTs are collected as column vectors in your graph. Thus, the x-axis is related to time and the y-axis is related to frequency. Since the FFT of a real-valued signal is symmetric, only half the frequencies have to be plotted. Therefore, the y-axis goes from 0 to Fs/2=128. WebBlock diagram of the log-mel spectrogram computation process.
