Using MATLAB, I approximated a .wav encoded audio file using a Daubechies Wavelet. With this data, I created a an array of data (wavelet coefficients) and then decoded it back to a .wav file. The original and my decoded file are indistinguishable. I then returned to the encoded data array, and sliced the file down the middle (along the middle row). Taking the top "half" of the data, I decoded it to a .wav file, and observed a noticeable degradation in quality.
@marx8926 If I can dig the code up. It's really quite easy to do.
