Message Forward

I believe he is saying "Beyond the realms of death." But I'm not 100% sure.


Matlab Code

  %% Joshua Long
  %% ECE 301
  %% HW 1.2 Hidden Message
  
  %% clear memory
  clear
  
  %% clear console
  clc
  
  [data, sample_rate, bits_per_sample] = wavread('N:\Personal\ECE301\Jpforward.wav');
  
  %%Play the data from a wav file:
  wavplay(data, sample_rate);
      
  %% Reverse a column vector
  col_vector = flipud(data);
  
  %%Play the data from a wav file:
  wavplay(col_vector, sample_rate);
  
  %%Save a wav file:
  wavwrite(col_vector,sample_rate,bits_per_sample,'N:\Personal\ECE301\Jpbackward.wav');


Message Backwards

Compared to the message forwards the message backwards was easier to distinguish what was possibly being said. I believe he said "I took my own life."

The audio file on this page contains the segment of the song backwards.
