Mel spectrogram - MATLAB melSpectrogram
https://www.mathworks.com/help/audio/ref/melspectrogram.html
Use the default settings to calculate the mel spectrogram for an entire audio file. Print the number of bandpass filters in the filter bank and the number of frames in the mel spectrogram. [audioIn,fs] = audioread( 'Counting-16-44p1-mono-15secs.wav' ); S = melSpectrogram(audioIn,fs); [numBands,numFrames] = size(S); fprintf( "Number of bandpass filters in filterbank: %d\n" …
audio - MATLAB - Spectrogram function - Stack Overflow

load handel; % 'handel' is a MAT-file which is shipped with MATLAB as an example x = y/100; % Decrease volume player = audioplayer(x, Fs); play(player,[1 (get(player, 'SampleRate')*10)]); spectrogram(x); Spectrogram(x) prints this, when x=y/100: Spectrogram(x) prints this, when x=y/1:
Spectrogram using short-time Fourier transform - …

N = 1024; n = 0:N-1; w0 = 2*pi/5; x = sin (w0*n)+10*sin (2*w0*n); Compute the short-time Fourier transform using the function defaults. Plot the spectrogram. s = spectrogram (x); spectrogram (x, 'yaxis') Repeat the computation. Divide the signal into sections of length n s c = ⌊ N x / 4. 5 ⌋.

[S,F,T] = spectrogram(x,128,120,128,1e3); imagesc(myAxe, T, F, log(1+abs(S)) ); %plot the log spectrum set(myAxe, 'YDir' , 'normal' ); % flip the Y Axis so lower frequencies are at the bottom
matlab - How do I plot the spectrogram of a wav file ...
https://dsp.stackexchange.com/questions/2696/how-do-i-plot-the-spectrogram-of-a-wav-file
A spectrogram can only show one channel at a time. Either make one spectrogram for each channel, or average your channels together into one. Here's an example of the syntax I found with a quick google search: [y, fs]=wavread(fileName); % Read wave file left=y(:,1); % Left channel right=y(:,2); % Right channel then you can do spectrogram(left)
