I am basically trying to detect mu waves. I'm pretty sure i saw a significant drop in the alpha band and want to make sure by using the spectrogram. This exercise plots wideband and narrowband speech spectrograms for a user-designated speech file. 2020-04-12 melSpectrogram applies a frequency-domain filter bank to audio signals that are windowed in time.

melSpectrogram applies a frequency-domain filter bank to audio signals that are windowed in time. You can get the center frequencies of the filters and the time instants corresponding to the analysis windows as the second and third output arguments from melSpectrogram.. Get the mel spectrogram…

S = spectrogram (x) returns the spectrogram of the input signal vector x. By default, x is divided into eight segments. If x cannot be divided exactly into eight segments, it is truncated. Mel spectrogram, returned as a column vector, matrix, or 3-D array. The dimensions of S are L -by- M -by- N, where: L is the number of frequency bins in each mel spectrum. NumBands and fs determine L. s = xspectrogram (x,y) returns the cross-spectrogram of the signals specified by x and y. The input signals must be vectors with the same number of elements.

The sound spectrogram of a speech file is an image map of the sequence of short-time log (or linear) spectrums, where each spectrum is obtained from an STFT analysis of a frame of speech, and subsequent spectrums are obtained from Calculate Mel Spectrogram.
