audiosignal processing

How can i convert a audio file(i.e SONG) into a analog signal in signal processing ?? I am learning signal processing for my college project.

wavread() the audio file. sound() the contents of it to send the signal to the built-in audio. If there is a speaker or headphones jack on the system, the analog signal can be pulled off of that.

MATLAB: Spectrogram of a song

Your song may be a two-channel stereo file. Stereo files are (Nx2) matrices.

Try this:

[x(:,1),fs]=audioread('estrellita.mp3');
window=hamming(100,'periodic')
spectrogram(x,window)

then this:

[x(:,2),fs]=audioread('estrellita.mp3');
window=hamming(100,'periodic')
spectrogram(x,window)

to see what works best for you.

MATLAB: Radio button to play song

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.
