The spectrogram view shows that each key is dialed for half a second, with half-second silent pauses between keys. 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.

How can I plot spectrogram without using Learn more about plot, spectrogram MATLAB Use the spectrogram function to measure and track the instantaneous frequency of a signal. Generate a quadratic chirp sampled at 1 kHz for two seconds. Specify the chirp so that its frequency is initially 100 Hz and increases to 200 Hz after one second. Using spectrogram (, 'freqloc') syntax and adding a 'freqloc' string (either 'xaxis' or 'yaxis') controls where MATLAB displays the frequency axis. Using 'xaxis' displays the frequency on the x -axis.

Hi, I need help. How can I crop a part of the spectrogram? For example in the figure below I need to cut out the part of the spectrogram marked in red with the letter "A" and save it as an image.

in the frequency domain, and these can be investigated using a spectrogram—that is, a representation program MatLab, one of the most known alternatives is GNU Octave.

[s,w,t] = spectrogram (___) returns a vector of normalized frequencies, w, and a vector of time instants, t, at which the spectrogram is computed. This syntax can include any combination of input arguments from previous syntaxes.
