Error in audiowrite command

91 views (last 30 days)
I am working on audio processing. I have a audio vector and I want to save it as a audio file. I tried this code, but it has the coming error:
audiowrite('Output.wav',o,fs)
_ Error using audiowrite>validateFilename (line 323) Cannot create file Output.wav. Permission Denied.
Error in audiowrite (line 105) [props.filename, fileExisted] = validateFilename( props.filename );_

If Output.wav already exists in your current directory then it is either not owned by you or you do not have permission to write to it.
If Output.wav does not already exist in your current directory then you do not have permission to write in your current directory.
The most common cause for a problem like this is that you have your current directory set to one where MATLAB is installed instead of being set to one of your own directories.

Use cd to change directories

In the command line, execute "cd .." as often as needed to get to the root of your PC. Then use "cd FOLDERNAME" to navigate to location where you have your .m script.
