- 20 bit recording is only begining to appear in recording studios
- producing the master copies. The 20bit master MUST transfered to a 16
- bit format as in the case of a CD. The current technology (DCC omitted)
- CANNOT handle the 20 bit format. However the accuracy of the 16 bit
- information on the CD may be truer to form when originating from 20 bit
- master than from a 16 bit.
-
- CD and DAT will continue to be 16 bit regarless of the resolution of the
- master.
