Analysis of Super Bit Mapping (an old Sony technology) from a view of Physics and Sound/Audio

Although developed in the years before the 21st century, this technology that is widespread in Japan and the U.S. is predicted to live on in the age of ‘Hi-Res Audio’. DSEE HX presents high quality sound from compressed files while SBM makes a compressed (CD Quality) file with high quality sound. Many pros will choose SBM for their final distributed piece. It is the same 16 bits, only better. Whether the companies will continue to use it (Sony DADC) or not will depend upon whether any new alternative technologies emerge.
Sony itself was responsible for its MD popularization until the early 2010s. As the relics of the past subside, and ATRAC (.oma) becomes virtually unplayable on most devices including Walkmans, their attention turned to their Japanese Music Organization’s Hi-Res efforts and the FLAC file format. It is unclear whether Super Bitmapped Audio will retain its characteristic after being ripped from a SBM CD in 16 bit audio WAV.
While the standard of CDs may seem too low, people were just as content with mp3 and wma. The fight against lossy audio is ongoing, this time led by the mobile market and the Japanese PC market (In 2016, NEC’s Note Standard and Toshiba’s had 4K and Hi-Res support). The Hi-Res earphones may not be as costly 10 years on. ATRAC is never mentioned as a bad example.
There exists a SBM for Video. Recording on SSMS RE in 24 bit 192 kHz may be impossible. This is avoided by configuring microphones correctly and using compatibility mode (Win Vista). There were restrictions in the beginning anyway. Your only choice is to edit Hi-Res files of a Recorder. The software focuses on editing/mastering and SBM output. Recording is an entirely different matter. I don’t want 24 bit 48 kHz or 96 kHz to be the maximum, but it could be. The first thing is to understand SBM and disk writing speeds (16 is good?) both physics and then find a potential business idea if possible.
