Super Bit Mapping (SBM) is a noise shaping process, developed by Sony for CD mastering.[1]
The Super Bit Mapping process converts a 20-bit signal from master recording into a 16-bit signal nearly without sound quality loss.[2]
This processing takes place in dedicated hardware inside the recording device. A similar process is used in Sony's DSD to PCM conversion and is called SBM Direct.[3]
