Checking the noise shaper (noise
shaped dithering)
You can use the noise shaper when creating an audio CD
from master files of 24-bit songs. (See "Creating an audio
CD" on page 82.)
You can check the effect of using the noise shaper when
creating an audio CD in advance.
NOTE
The noise shaper only affects the audio CD created. It has no
effect on the original master files themselves.

What is a noise shaper?
Since standard audio CDs use 16-bit quantization, this
unit automatically converts master files created from 24-
bit songs to 16-bit when writing a CD. When the bit rate
is converted, a very low level of quantization distortion
usually occurs at points where sound becomes inaudible,
but you can reduce this distortion by turning the noise
shaper on.
The noise shaper in this unit reduces quantization
distortion by using a dithering technique that adds
random noise below the quantization steps.

Mastering
screen is open,
