How does ssse4 or whatever help audio performance?
Music-playing software that makes proper use of the various SSE instruction sets (the first was developed in 1999 for the PIII), loads the CPU less (is more efficient) than software that doesn't.
The argument is that this improves sound quality. Obviously, the increased efficiency imposes a maintenance overhead that may explain why the relevant instructions do not seem to be used by "mass market" players.
How is the comparison made?
A processor that supports (say) the SSE4 set also supports earlier ones. Different versions of the software under test (i.e. one employing SSE instructions only or SSSE3 or SSE4, etc) can readily be run sequentially on any computer with a suitable CPU and the sound compared.
(Adherents of the Church of the Double-Blind of course have to make their own arrangements but that's the gist of it for the rest of us.)
