audiowrite.m needs a long time to save

Hi!

I think this is a bug report but probably for Windows10 and a dirty fix.

When I try to write a lot of *.wav in short succession, at one point audiowrite needs a long time to save the files.

I narrowed the error down to the subfunction 'filepath.Writeable' in audiowrite.m . So if you desperate (like me) you can comment out the line

% if ~filepath.Writeable

% error(message('MATLAB:audiovideo:audiowrite:fileNotWritable', filename));

% end

(Matlab 2020) and hope for the best.

Greetings,

Ewald

Hi Ewald,

Can you point out what file are you writing and share the code as well (if fine with you), because I wasn't able to reproduce the issue?

That would help us gather more understanding about the bug and give you a proper solution for the problem.

Hi Ewald,

There is a question I have:

for i=1:100
        ....
        signalfolder=strcat('C:\Users\....);
        mkdir(signalfolder);
        .....
end

What is the need to make directory 'C:\Users\...'? Can't you directly write audio to the needed file, which I think is 'RandSignal.wav' in your case?

The reason is that each signal needs its own folder. I have no choice here.

Hi Ewald,

Don't know whether I ran into the same issue because of the same reason or not, but in my case the folder in which I was trying to write was read-only. Just edit windows properties in that folder and remove "read-only".

Hope it helps! ;)
