Dithering
Ozone contains a comprehensive set of dithering tools that allows you to prepare studio-quality audio
for CD and other formats by eectively converting and dithering audio to 24, 20, 16, 12, or 8 bits. Note
that the dither tool is independent of the Maximizer module.
Key Features
Includes iZotope MBIT+ Dither for exceptionally transparent conversion to dierent bit depths.
This is a proprietary iZotope word length reduction technology that reduces quantization
distortion with minimal perceived noise. While this might sound like a paradox, MBIT+ is a very
smooth, quiet, and almost “analog sounding” technology.
Unique set of bit meters and DC oset (direct current oset) meters provides a complete view of
the digital bitstream and conversion process.
To enable/disable the feathering algorithm and compare its eect on the audio signal, click on the
Dither button underneath the master I/O meters. The dither power button will illuminate when dithering
is active and aecting the audio.
To access the settings for the dithering section, click on the Dither button in the lower right-hand
corner of the interface. The dithering section contains the following controls:
Noise Shaping Curve:
This graph shows the noise-shaping profile curve, as displayed across the frequency spectrum. The
graph displays the general frequency curve of the specific dither noise profile that is used, depending
on the algorithm.
Bit Depth
This control allows you to set the target bit depth for the audio. When mastering for a CD, for example,
you would want this set to 16 bit.
