Using the noise shaper (Noise Shaped
Dithering)
What is noise shaper
ª
Audio CDs use 16-bit quantization, so the master file data
is automatically converted to 16-bit.
In general, bit conversion results in a very low level of
quantization distortion at points where sound is removed,
but you can reduce this quantization distortion by turning
the noise shaper on.
The noise shaper in this unit uses a dithering technique
that adds random noise below the quantization steps to
reduce quantization distortion.
1. When the
Mastering
screen is displayed, press
the F3 (
NSD
) button to open the
NOISE SHAPED
DITHERING
screen.
2. Press the F4 (
ON/OFF

shaper function to
ON
