How to generate the spectrogram of a wav file in Matlab ...
https://stackoverflow.com/questions/38359735/how-to-generate-the-spectrogram-of-a-wav-file-in-matlab-with-frequency-on-the-x
My code which generates the spectrogram with the frequency on the y-axis and the time on the x-axis (Matlab code): [song, fs] = wavread ('filename.wav'); windowSize = 256; windowOverlap = []; freqRange = 0:300; spectrogram (song, windowSize, windowOverlap, freqRange, fs, 'yaxis');

Mel spectrogram - MATLAB melSpectrogram - MathWorks
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" …
Spectrogram using short-time Fourier transform - …
https://www.mathworks.com/help/signal/ref/spectrogram.html
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 ⌋.
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)

1. I run the script in Matlab which outputs the 1920×1080 video and contains the same length as the audio file, 2. Drag the video into Adobe Premiere with the Graphics playback bar template. 3. Drag the audio into the start to match the animation. 4. Export the 1920×1080 video. The process for one audio file takes about 2-3 minutes from start to finish.
