Three options are available for bit depth:
- 16 bit - default

Hybrid mode
Hybrid mode provides all the advantages of lossless compression with an additional bonus. Instead of creating a single file, this mode creates both a relatively small, high-quality lossy file that can be used all by itself, and a "correction" file that (when combined with the lossy file) provides full lossless restoration. This means never having to choose between lossless and lossy compression.
Bit Rate
This is only available when Hybrid Mode is selected.
There are options fro 2.2 bps to 8.0 bps. The default is 4.0 bps.
