Abstract

In the introduction to this book, we saw that the last stage in the coding chain is the human ear. A good understanding of how the human ear works can be a powerful tool in the design of audio codecs. The general idea is that quantization noise can be placed in areas of the signal spectrum where it least affects the fidelity of the signal, so that the data rate can be reduced without introducing audible distortion.
