As I continued to research and development of sound player, I will notice that the transfer method
of the memory changes the sound quality in the MMX and SSE and AVX. Memory output circuit of
the CPU, when it was thought to change by the CPU instructions and register, I found the answer
to the sound quality is of course changed. By the hypothesis grounds, it was named the technique
of new jitter suppression. "Rewrite memory"
"This is to achieve low jitter in all sound player"
