Homework #1
Problem 1
Jeremiah Wise
This Program plays part of a Judas Priest song first in the forward
direction then in reverse. Then in takes the reversed data and
writes it to a .wav file.
%}
%read sound file data
[data, sampleRate, bitsPerSample] = wavread('JudasPriest.wav');
%play sound file in the forward direction
wavplay(data, sampleRate);
%play sound file in the reverse direction
reversedData = flipud(data);
wavplay(reversedData, sampleRate);
%write reversed sound data to a .wav file
wavwrite(reversedData, sampleRate, bitsPerSample, 'BassAckwards.wav');
Played in reverse it sounds like it says "I took my life".
