NOTE I AM BRAND NEW TO MATLAB SO IF POSSIBLE PLEASE EXPLAIN AND/OR USE SIMPLE CODE

My professor asked me to write a code that will loop through my folder of four files creating a waveform, powerspectrum, and waveform for each file as well as saving those figures as a PDF before moving onto the next file.

This code is supposed to utitlize the listing = dir("PathName') function

Here is what I have

How on earth do I get this to work?

My Current Code:

dir("C:\Users\Karianne Kapfer\MATLAB\Assignment2\Soundfiles") %%the directory my files are in

for listing = dir("C:\Users\Karianne \MATLAB\Assignment2\Soundfiles")

%%Need to loop through the files

%%the graphs I am trying to make

fs = 64000

subplot(3,1,1)

plot(listing) <- This plot is also not working for some reason

xlabel("Samples")

ylabel('Amplitude')

title('Waveform')

hold on

subplot(3,1,2)

pspectrum(listing, fs)

xlabel("Frequency (kHz)")

ylabel('Amplitude')

title('Power Spectrom')

hold on

subplot(3,1,3)

s = spectrogram(listing)

spectrogram(listing,1024,[],[],fs,'yaxis')

publish('Assignment2MultipleFiles.mlx', 'pdf')

hold off

end

Please post code as formatted text, not as screen shot. Then the readers can copy&paste it to suggest a solution.

在 MATLAB Online 中打开

See: FAQ: How to process a sequence of files

Folder = 'insert your folder here';  % Sure that there is a sapce after your name?
FileList = dir(fullfile(Folder, '*.wav'));
for iFile = 1:numel(FileList)
    File = fullfile(Folder, FileList(iFile).name);
    % then audioread will help
end
