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 between 2 kHz and 4 kHz. The human ear is
most sensitive to this frequency range.
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.
Use POW-r dithering only for master outputs when playing back, use standard
dithering for other outputs: If this option is selected, then only the master outputs will be
dithered with the POW-r dithering algorithm. The individual outputs will use standard
dithering, i.e. dithering with triangular spread noise.
Smart dithering for export/CD burning (switch off dithering dependent on audio
material)
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 16-bit. If the original material is 16-bit, dithering
only occurs when there are modifications to the bit depth. Dithering is not calculated during
silence.
For virtual projects: This option is switched off by default. In this case, dithering only
occurs if the bit depth does not equal 16-bit.
Threshold for switching off dithering (autoblack): Specify a threshold value below which
any dithering noise that is created should be muted. The range of values in this case is
between -100 dB and -210 dB.
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.
