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 contains the segment of the song backwards.
