Whats the difference between the various ATRAC generations, and how well do they interoperate?
The following sections refer to Sony’s ATRAC. Sharp and Matsushita (among others?) have developed ATRAC chips of their own, though rather little has been made public about their evolution. While all manufacturer’s ATRAC versions interoperate and are based upon Sony’s original specification, it is not possible to compare their version numbers. Version numbers frequently serve to enumerate Minidisc/DSP chip generations as much as actual ATRAC algorithm changes, so there is no direct relation between version number and audio quality.
