uploaded:
lekt.exe v3.2 256 push4
lekt.exe v3.2 256 rax

better bass focus, tighter. vocal very good.
push4 soundstage more correct, but rax vibration give mellow sound, nice. i feel good emotion from both.

uploaded lekt.exe v3.3 256

optimized code of v3.0 masm, fix bugs. sound have more depth, good deep bass vibration.
4 kb file size (4096 bytes) seems useful for reading, matched cluster size, never fragmented. try it.

Excellent! Best Yet! More detail, better separation and depth of instruments and notes, especially on bass - great vibration. More excitement! Have to be careful not rip the headphone cable out the amplifier when doing my air guitar.

i was busy in this time, not good time for coding. just tried with stack, faster speed with stack memory.

uploaded:
lekt.exe v3.4 256
lekt.exe v3.4 256 stackmem

don't use variable in .data section, now .exe file have only 2 sections in PE structure. use stack as memory block for some small strings. sound more clean, more ease, but seems lost depth, a bit. maybe too many registers in use, affect latency? coz CPU have limited quantity of registers.
try them and compare to v3.3 256.

optimized masm code and tried SSE movdqa with xmm registers so there's 16 bytes copy once in each instruction. seems a bit more benefit coz more simple code in loop. don't know why AVX with ymm registers 32 bytes copy once, but SQ not better, even SQ lesser than xmm. will learn more.

try new versions:
lekt.exe v3.6 256 sse
lekt.exe v3.6 256 sse c2
lekt.exe v3.6 256 sse c3

sound stage very good, just enough 3 dimentions of sound, there's not 3D-effect. sound better.

Welcome back JC! Hope life has been good during your absence... and you are raring to go get in some testing - I have struggled to snatch time for much testing.
