Hello all,
I have been scouring the existing online help but cant seem to find exactly what I’m after. I have a folder with hundreds of 4 min wav files and want to produce a single spectrogram which contains them all. My initial thinking was to read in all wav files and somehow join them into one large file to later put into a spectrogram. Any help would be great appreciated!
Thanks,
Thomas

Something like this:
data_tot=[];
>> for i=1:numel(files)
data=audioread(files(i));
data_tot=[data_tot ; data];
end
audiowrite('file.wav',data_tot,Fs);

you have to make colomns from your data, you can add some lines to do this:
data_tot=[];
>> for i=1:numel(files)
data=audioread(files(i));
if size(data,1)<2
data=data';
end
data_tot=[data_tot ; data];
end
audiowrite('file.wav',data_tot,Fs);
and you have to check whether all your files are single audio files or double (left and right audio).
