a) Playing the file forward, the words are "beyond the realms of death."

Sound Files

This is the sound clip reversed with MATLAB: Media:jkubasci_Jpreverse_ECE301Fall2008mboutin.wav

This is the reversed clip played at half rate: Media:Jkubasci_Jpreverseslow_ECE301Fall2008mboutin.wav

b) After examining the sound clip reversed, both at normal and half rates, it was determined that a subliminal message exists. The subliminal message was determined to be "this life is mine".

MATLAB Code

soundreverse.m

% Reverse wav file and slow down
% Written by: Jeff Kubascik

% Read the sound file
[sound, fs, nbit] = wavread('Jpforward.wav');

% Reverse the sound file
reverse = flipud(sound);

% Write the reversed sound to a file
wavwrite(reverse, fs, 'Jpreverse.wav');

% Write the reversed sound at half rate
wavwrite(reverse, fs/2, 'Jpreverseslow.wav');
