MATLAB: How to save a .wav file into different path after processed

Anyone know how to save it into different path? Thanks

[y, fs] = audioReadNCU();
[y, fs] = wavToPreprocWav(y, fs);
band = wavToElectrode(y, fs);
y = electrodeToWav(band, fs);
sound(y, fs);
audiowrite('1_ace_8.wav',y,fs);

D = 'absolute or relative path to the folder where you want to save the file';
F = fullfile(D,'1_ace_8.wav');
audiowrite(F,y,fs);

Just put everything you want to happen in a single function.

And stop with the habit of including clc,clear all,close all. You obviously are not thinking about what that does, so don't include it.

MATLAB: How to process and rewrite multiple wav file into different 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.
