I tried to search the Matlab Help topics and got the following things I neede, but somehow it doesn't work and I cannot get the music file.
%Open the wave file
[y, Fs, nbits]=wavread('jpforward.wav');
%Play the file
wavplay(y,Fs);
%Reverse the file, play it, and write it out
reverse=flipud(y);
wavplay(reverse,Fs);
wavwrite(reverse,Fs,nbits,'reverse.wav');
