The distortion

We start off with our wav file. The very first thing we need to do with this file is convert it into a vectorformat that matlab using wavread

For help in using this function, use MATLAB's help command.
. After converting the the file to a vector, we play around with the coefficients andpowers, making sure each power is less than one. To check out the sound of each try, soundsc is a helpful function. Our group found 10*note.5+10*note.9+1*note y 10 x .5 10 x .9 x , where y is the distorted song and x is the original song, to be our favorite.
