Dithering depth in bits: Set the noise level used for dithering here. Input is in bits. You can
specify how many bits of the resulting 16-bits dithering should be affected. In most cases,
values between 0.5 and 2 will provide good results. Increase the value until distortion
effects are no longer audible. If you can't perceive any disturbances, values below 0.5 are
sufficient. If you want add a high level of noise to your signal, then add values between 8
and 12.
POW-r Dithering / Smart Dithering
POW-r #1 (dithering): This function uses a special dithering curve to minimize quantization
noise.
POW-r #2 (noise shaping): This function uses additional noise shaping across a wide
frequency range to extend the dynamic range by 5-10 dB.
POW-r #3 (noise shaping): This function uses additional, optimized noise shaping to
extend the dynamic range by up to 20 dB within the 4-20kHz range, which is the range the
human ear is most sensitive to.
Noise shaping minimizes side effects caused by bit reduction by spectrally displacing the
quantization noise above 10 kHz, which is the range the human ear is least sensitive to.
Which dithering mode sounds the best depends mainly on the audio signal.
Smart dithering for wave files: This option is set as the default. Dithering will only occur
on 16-bit exports and when burning CDs if the bit-depth is not 16 bits. If the original
material amounts to 16-bits, dithering only occurs when there are modifications to the bit
depth. Dithering is not calculated during silence.
Smart dithering for virtual projects: This option is switched off by default. In this case,
dithering only occurs if the bit depth does not equal 16-bits.
Advanced buffer settings
In this dialog you can optimize buffer settings for your virtual project, for hard disk caching
and for plug-in manipulation. If no drop-outs or scratches are heard during playback, you
don't have to make any changes.
