Noise shaping in audio is most commonly applied as a bit-reduction scheme. The most basic form of dither is flat, white noise. The ear, however, is less sensitive to certain frequencies than others at low levels (see Equal-loudness contour). By using noise shaping the quantization error can be effectively spread around so that more of it is focused on frequencies that can't be hear… WebDithering.
