Hello, I have to read a Audio File (.wav) into a vector.

I know how to plot it:

info = audioinfo('sound.wav');
[y, Fs] = audioread('sound.wav');
t = 0:1/Fs:info.Duration;
t = t(1:end-1);
plot(t,y);
xlabel('Time');
ylabel('Audio Signal');

But this Sript does not read the Audio into a Vector.

I also tried to read every single Sample, but this is to complex and I get error after error. Is there a simple way to do this?

It would be helpful if you could share the error messages as well as your sound.wav file.

Sorry, I cannot upload the file, because the forum doesnt accept the .wav filetype. And I have already deleted the code with the error messages. But next time I will upload everything.
