i am trying to write a MATLAB code to process two different .wav files the first one include a recording for the word “audio” in an approximately 5 seconds length .wav file?

recObj = audiorecorder;
disp('Start speaking.')
recordblocking(recObj, 5);
disp('End of Recording.');
y = getaudiodata(recObj);
figure
plot(y);
title('Hello World!')
audiowrite(recObj, 1, 22050); 
play(recObj);

this what i was able to reach in the code but i keep getting a error like this

Error in audiowrite (line 111)

props = parseInputs(filename, y, Fs, varargin);

Error in Test1 (line 9)

audiowrite(recObj, 1, 22050);

you have to tell audiowrite a file name. You do not have to tell it the number of channels. You have to pass the data to be written to it, which is y, not the recording object

ok but how can i do it when i am trying to create the .wav file from this matlab script, it is not a seperate file i am recording on this script and from this script i want to create a .wav file

[Walter Roberson]

audiowrite('NameOfFile.wav', y, Fs)

thank you so much, it is working now but how can i save the .wav file or where can i find it?

[Walter Roberson]

If you do not provide a directory as part of the file name then it will be saved in your current directory. You may wish to provide fully qualified file name.
