radio button to play song

 im trying to come up  with the   code for selecting a radio button and  making it  play a  song...  i have  asked my  instructor with no  luck,  my book  says nothing...  if  someone  can  point me in a direction...  that would be great. !

I have had success with the following.

In the opening function:

% Audio Players
[y,Fs,NBITS]=wavread('punch.wav');
handles.Punch = audioplayer(y,Fs,NBITS);
[y,Fs,NBITS]=wavread('electric buzz.wav');
handles.Buzz = audioplayer(y,Fs,NBITS);
[y,Fs,NBITS]=wavread('I_can_see.wav');
handles.See = audioplayer(y,Fs,NBITS);

and in the callback:

play(handles.Buzz); % or whichever sound is appropriate for the selected button/control

This preloads the audio and player object when the GUI is opened and then it can be controlled from the callbacks in the GUI without a delay.

If you're not using a GUI created in GUIDE, initialize the audio players in whatever function creates your GUI window. Save them as UserData in the button group or button that will use them and then you'll have access to them in the callback by using

get(hObject,'UserData')

 and  what if  its  an mp3  not wav file?

[Benjamin Avants]

You can read pretty much any audio file with

[y,Fs] = audioread('filename') ;

instead and the audio player will be initialized as

audioplayer(y,Fs);

If the audio data is in floating point format (shouldn't be with mp3) then you'll need to specify NBITS, the bits per sample.
