ATRAC Type-S: "Type-S" apparently refers to a new chip containing an improved version of the ATRAC3 codec as well as the ATRAC1 Type-R codec; the combination of the two is called DSP Type-S. From Sony's information sheet: "The two new products MDS-JB980 and MDS-JE780 in the press announcement at CeBIT both adopt the newly developed DSP (Digital Signal Processing) IC chip "CXD2664R." The CXD2664R chip has two DSP functions; one is ATRAC DSP and the other is ATRAC3 DSP. The ATRAC DSP, the TYPE-R algorithm which is the version of the highest grade, is adopted, and the highest sound quality can be obtained at the time of recording. And the ATRAC3 DSP, the algorithm of a newly developed DSP is adopted. It can reproduce the track recorded in MDLP mode in very high sound quality at the time of reproduction. This works in the same way for the disc recorded by other MDLP products. Sony calls the DSP functions of the CXD2664R chip "ATRAC/ATRAC3 DSP TYPE-S". In other words, "ATRAC/ATRAC3 DSP TYPE-S" is a combination of "ATRAC DSP (TYPE-R highest Version)" and "ATRAC3 DSP (newly developed)."
