clear all

% Read file
[sound, sampleRate, bits] = wavread('jpforward.wav');

%play file in forward direction
fprintf('Press enter when music stops...\n')
wavplay(sound, sampleRate);
pause

%play file in reverse
reverseSound = flipud(sound);
fprintf('Press enter when music stops to write to file...\n');
wavplay(reverseSound, sampleRate);
pause

% Write reversed song to file
wavwrite(reverseSound, sampleRate, bits, 'jpreverse.wav');
fprintf('File write complete.\n');

Reverse File

Media:jpreverse_ECE301Fall2008mboutin.wav

My Conclusion

To be real honest, I can't even hear the words of the song played forward. The quality is lacking. When played backwards, I guess it sounds like "IIIIIII cooked myyy wiiiife." Interesting.
