Audioread filname not on specified path / Restoredefaultpath not working duplicate file name

Hi! I'm trying to get my code working again, but whenever I run audioread() it tells me that it was not specified on the path. This is the offending line:

filename = audiovideo.internal.absolutePathForReading(...
  filename, ...
  'MATLAB:audiovideo:audioread:fileNotFound', ...
  'MATLAB:audiovideo:audioread:filePermissionDenied');

I tried restoredefaultpath, but it tells me that there are duplicate directory names. I've tried deleting the one from the path that i could find, but it still wouldn't run. I've reinstalled MATLAB on my computer twice, so maybe that's what it's from, but I don't know how to fix that. I'm not quite sure what the problem is, but it says the error is from this line:

matlabpath([userpath, RESTOREDEFAULTPATH_result]);

Any help is greatly appreciated, I'm really at a loss for what to do.

I’m not exactly sure what you’re doing.

Type this in your Command Window:

which('audioread', '-all')

and you should get:

C:\Program Files\MATLAB\R2016a\toolbox\matlab\audiovideo\audioread.m

or something similar.

How did you call audioread initially? What was the error?

Hi! Yes that is what i got when i ran which('audioread', '-all')

I called it just by reading in a file from my computer and saving it like this

 filename = '/Users/SebastianiChen/Documents/PERCH Research/Distinct Heartbeat/Z02415-01_F.wav'; 
[x, ~] = audioread(filename)

The error was that the filename specified was not found in the MATLAB path, but I'm not sure exactly what filename it's referring to

I didn’t realise you’re using Linux. I added that to the tags. I have no experience with Linux (running Windows here), so I don’t know what system utilities you have available to find and return file names and paths.

If you want to see if your sound file is on your MATLAB path, do the same thing:

wav_path = which('Z02415-01_F.wav');

then use ‘wav_path’ as your file name, since that will contain the full path as well as the file name.

If it’s not on your MATLAB path, the only other approach I can suggest is that you use the complete path and file name. On Windows, that would begin with the disk volume name (here: C:\) and all the necessary directories and subdirectories.

Okay, thank you! I think I found the problem. Thank you so so much :)

Hi Sebastien ,can you say how did you solve the problem? I have a similar problem...

Hello, I have a similar problem. I am trying to extract some frames from .avi file. Matlab has a sample code with sample file 'rhinos.avi'. I tried replacing my .avi file in the same location as rhinos.avi file. But Matlab keeps giving me the same error: Error using VideoReader/init (line 607) The filename specified was not found in the MATLAB path.

Error in VideoReader (line 172) obj.init(fileName);

Any inputs would be appreciated. Thanks.
