audioread() randomly stops working

Hi all,

I keep having this issue where the audioread() function will stop working. If I try to import a .wav file, I get the 'Too many input arguments.' error, even though there is only 1 file in the directory by that name. If I restart Matlab it will work again, but I hate to lose all of the data I've been working on just to get the function to work again.

It also seems like this affects the sound() function as well. Could one of my toolboxes have gotten corrupted?

Thanks for any help!

Please show a full trace of one of the "Too many input arguments" error occurring.

I'm not sure how to do a full trace, but hopefully this is what you're looking for:

disp(err)

message: 'Error using <a href="matlab:matlab.internal.language.introspecti...'
    identifier: 'MATLAB:audiovideo:audioread:fileNotFound'
         stack: [1x1 struct]

disp(err.message)

Error using audioread (line 74)

disp(err.stack)
    file: 'C:\Program Files\MATLAB\R2014b\toolbox\matlab\audiovideo\audioread.m'
    name: 'audioread'
    line: 74

disp(err.identifier)

MATLAB:audiovideo:audioread:fileNotFound

disp(err.stack)

That is not even close to "Too many input arguments".

The file you are trying to open cannot be found. Perhaps you cd'd to a different directory.

[jmerritt]

I didn't CC into another directory, though - I've confirmed that my current file path contains the file I'm trying to load via 'pwd' and 'dir'. It just ... won't open it.

I'm working with some code that imports a bunch of files to train models, so perhaps there's a flag that gets overwritten in there that messes with audioread() somehow?

[Walter Roberson]

One obscure possibility is that you might be running out of Open File Descriptors, if you have a bunch of open files that were never closed. Try

fclose('all')

when it happens, and see if you can then repeat the command.

Ah, I fixed the issue! Turns out, there was some errant code adding directories to my search path. Removing them fixed the issue.

Thank you for the help! I'll definitely keep that command in mind for the future.
