Is it time for a 448 mqnplay for comparison?
4.44 is pretty sorted

it uses hardware prefetching which can't go over page boundaries, so the buffers need to be page aligned, currently 2048 bytes, 448 is 1792 bytes and would have irregular noise due to hw prefetch issue.
I understand the theory
It does sound logical
It's just that I've tested up to 4.33
And I'm still using 3.14/3.39 avx 2 for listening
Just wonder if its a factor
If we had a new 448 we could compare just to be sure 512 is the best fit

hmm... 448 * 4 = 1792

how about
448 * 16 = 7168
7168 = 7 * 1024

very good

first buffer 1792
second buffer 3584
third buffer 5376
so third buffer goes over page boundary

4.42>>>4.44
didnt like 4.44

seems like your trying to remove noise and taking detail, hf, vibration with it

just trying things out, this may have been a dead end.

Maybe you'll like 4.47, have done an sse2 version as well.

4.47 was improved, still short on micro micro detail,hf/LF, flow, macro detail is vgood very clear, however whispers in a crowd at a live recording sound like rustling of a bag in comparison to 3.39avx2

didnt test the others

If that's what is in the recording, it is the 'duty' of the player to let it be heard.

yes, but it could have been a careless whisper.
