When i try to open a wav file, i got this error:

Error using wavread (line 67)
Invalid Wave File. Reason: Cannot open file.
Error in gui>Open_Callback (line 125)
[mySong,sf]=wavread(myFile);
Error in gui_mainfcn (line 96)
        feval(varargin{:});
Error in gui (line 42)
    gui_mainfcn(gui_State, varargin{:});
Error in
@(hObject,eventdata)gui('Open_Callback',hObject,eventdata,guidata(hObject))
Error while evaluating uimenu Callback

my code:

function Open_Callback(hObject, eventdata, handles)  
global pl;  
global sf;  
[FileName,PathName]=uigetfile('*.wav');  
myFile=[FileName,PathName];  
[mySong,sf]=wavread(myFile);  
[M N] = size(mySong);  
i=1:1:M;  
axes(handles.axes1);  
axis([1 M min(mySong) max(mySong)]);  
plot(i,mySong);  
pl=auidoplayer(mySong,sf);

Invalid wave file error (line 67)occur because matlab supports specific format of audio file i-e PCM . first convert your audio from mp3 to pcm then place into current directory and run the program

I tried 2 different wav files. They give this error:

Undefined function 'auidoplayer' for input arguments of type 'double'.

Error in gui>Open_Callback (line 131) pl=auidoplayer(mySong,sf);

I thought this was marked as solved. Maybe you want audioplayer instead of auidoplayer.

You didn't construct the full filename properly. Use the fullfile() function:

fullFileName = fullfile(PathName, FileName);
[mySong, sf] = wavread(fullFileName);
