How to process and rewrite multiple wav file into different folder?

I have a folder with multiple song. After I processed these .wav, I also want to rewrite and put it into different folder. How to do this?

However, this .wav has been already processed from multiple function (wavToPreprocWav.m, wavToElectrode, and electrodeToWav)

Thanks

[y, fs] = audioReadNCU();
[y, fs] = wavToPreprocWav(y, fs);
band = wavToElectrode(y, fs);
y = electrodeToWav(band, fs);
sound(y,fs);
audiowrite('/Users/epriwahyupratiwi/Downloads/GUI/tut1/song test/new.wav',y,fs);

What is wrong with your approach already, are you getting any errors? You are using audiowrite with the minimum set of required inputs.

I don't know how write the code to process all the file in the folder.

Hi Epri,

It is my understanding that you are trying to read multiple files one by one,process it and save the processed file to a different location. This can be done as shown in the following example (assuming all the files in the read folder are audio files). Refer to the dir documentation for more details.

FileList = dir('*.*'); 
for i = 1:length(FileList) 
    file = FileList(i).name; 
    % perform all necesary functions  
    % [y,fs] = audioread(file); 
    % [y, fs] = wavToPreprocWav(y, fs); 
    %band = wavToElectrode(y, fs); 
    %y = electrodeToWav(band, fs); 
    %sound(y,fs); 
    write_filename = "new_" +num2str(i)+".wav";  
    %write_directory is the path to the directoy where  
     %the processed file needs to be saved
    audiowrite(write_directory+write_filename,y,fs); 
end 

Hope this Helps.

as the folder contains multiple files what should be given in place of name
