Whilst I have not listened to JPlay and I am aware of the misgivings many have about JPlay's SQ here, surely the features quoted - MQn as a service, DMA transfer, WDM-KS (and may be large memory pages, but I wouldn't know) are potentially where MQn ought to be going now that we are getting pretty small changes in the latest 4.xx versions?

Easy for me as a non-coder to say, but there would seem to be more 'low hanging fruit' in those areas than continuing refinement of WASAPI MQn?

What is scary is that starting from a MQn base of 4.74 or thereabouts, and implementing those additional enhancements, how good would the SQ end up being?

why would a service sound better than a process anyway?

service has a lot of extra junks. security group, failure handling...
a service is also embedded within a svchost process... all these complications...

i bet if service sounds better, that would add 1% SQ.

think i once tweak mmcss and other audio services to have kernel or driver privileges, SQ didn't increase.
sound was tightened, texture seems improved, impressive at first, but incorrectly, because sound was also hardened. not natural.

squeezelite sounds better running as a service. slimserver sounds better running as a service etc

jplay is such a scam in my opinion. always trying to impress people with technical things.

if they want to impress, i think they should install jplay as a driver. why not. already doing service.

2pc... lan after lan... cpu locking...
if they actually use their ears, simple coding sounds 10 times better.

if you want to know how wrong jplay sound?
go to your kids music school. and listen to actual musical instruments.

if you listen to jplay, maybe it isn't the answer.

One question if I may - what settings are you using in Pro Audio Clock Rate with the different 128, 256, 512 versions? I am using 3.61 512 Control and had Clock Rate at 448 as you suggested. But with SSE2/3 512 MQnplay versions (I do not have avx so many versions have to pass me by) I moved Clock Rate to 512 with slightly better results I think and have left it there since.

I am assuming that Gordon is not now changing Clock Rate within his code, which was the case a while back, I believe.

Thank you as always

think the mqnplay is still changing clockrate which i could really live without
id imagine its more difficult to hear the differences with sse2 versions as it doesnt have the same agility (ability to display micro detail) as avx
with avx the differences are still noticeable with two or three comparisons

ks probably needs alot of mucking out,
think were close to a really good version of avx mqn
improvement is infinite
were going to have to stop somewhere

it's not a scam, it's a bargain for what it is. Just they are so far up the creek that there is no going back to a simpler solution.

i can only imagine service is better because it has better privilege than normal process.

sbgk, have you tried using manifest to 'upgrade' the privilege of mqn?

last time i heard ks vs wasapi, ks has more quantity in bass and seems smoother. that's was it.

make a perfect wasapi mqn first...
