Hello.
I'm trying to load a .wav file, based on user input. For testing, I am using sample.wav. When I type audioread('sample.wav'), it works perfectly, but when I type:
fileName1 = inputdlg('Type the filename of the .wav file you would like to upload');
% A dialogue box pops up and I type sample.wav into it
audioread(fileName1);
This results in the following error:
Error using which
Argument must contain a string.
Error in audiovideo.internal.absolutePathForReading (line 7)
whichFileName = which(filename);
Error in audioread (line 74)
filename = audiovideo.internal.absolutePathForReading(...
What am I doing wrong?

Saad - what is the line of code that you have written to load your audio file? Are you using audioread?

As input() takes only integers. Convert the file name to string.
fileName = string(input('Type the filename of the .wav file you would like to upload')); audioread(fileName);
