Sounds Files
Normal Reverse Speed - Judas Reverse @ 44100HZ
Slow Reverse Speed - Judas Reverse @ 22050HZ
Matlab Code
clear clc fileInput = 'jpforward.wav'; %Input file origArray = wavread(fileInput); %Array containing input file inputLength = length(origArray); %gets length of array count = 1; %Initializes counter for count = 1:inputLength; %Simply reverses the array using a loop outputArray(inputLength - count + 1) = origArray(count); end %Sampling rates used: 44100HZ and 22050HZ wavplay(outputArray, 44100); %Plays the sound file wavplay(outputArray, 22050); wavwrite(outputArray, 44100, 'Judas Reverse_44100HZ'); %Saves sound file wavwrite(outputArray, 22050, 'Judas Reverse_22050HZ');
Results
This part of the homework was fairly straightforward. I chose to use two different sampling rates so that it could be listened to at different speeds.
It took me a long time to decipher what was actually being said in the song. But, it turns out that the singer says, "Beyond the realms of death" (when played forward). When the song is played in reverse, it sounds like he's saying, "I took my own life".
