Which HQP Filter are you using?

Oh hang on whats this?

Never knew about the counter and needed to keep an eye on it.

So are you saying, it doesnt matter how big the counter gets, as long as its an Apodizing filter it doesnt matter?

It only matters if its a Non Apodizing filter?


Yes that’s the case.

Yes, exactly.

The two counters (Limited and Apod) are from different point in the processing pipeline.

Apod counter is based on analysis on the input, before the data enters processing. So the processing won’t affect it’s value.

Limited counter is based on analysis of the output, last thing before data goes out to the DAC. So here processing affects the value and this one should thus always stay zero.


Well, been testing the new Windows 11 Pro,13900K build and was able to do this with no external gpu. Using Asus AI Overclocking. 990 Pro and Corsair Dominator 32gb 6000 DDR5
With convolution and peq

Sadly, still stutters using sinc-Mx PCM-DSD512 on most of the higher EC modulators, 1 stutter on DSD5EC.

What’s strange was I got this last night before enabling AI Overclock when it was stock and played without stutters. I tried all combos of check and unchecks of Adaptive and Multi and not working tonight.

Any tweaks to try?

I would suggest modulator ASDM7ECv2 and DSD256 instead, not sure if that requires more or less CPU though but I am pretty sure it will sound slightly better.

You can also lessen the CPU load by using “Adaptive output rate”, but then you have to select another oversampling filter (I use ext3).

Here is my signal path:

sinc-Mx and other sinc- filters are ones that benefit from GPU offload big time. Without offload, it will eat a lot of CPU time and you would need to have 12 - 16 performance cores to spare. So those may be better on the AMD CPUs that have more cores.

It is 64 million taps at DSD1024 to process, quite a lot of computations to do at almost 50 MHz sampling rate.


Congrats on your 139K built ! Still on Gustard R26 ? How does it sound @1024 with 7EC for you ?

With Holo Audio MAY I find 1x: gauss-xla @1024 is amazing. But truly impressive, rather, if you can do Nx: gauss-xla 7EC@1024x48

On Sinc-Mx, yeah, Jussi explained why… with my 129KS “no GPU” build I can only do stable @256x48 with this.

PS: you mention you do convolution and PEQ all together - may I ask why at same time ?



I have a May now and R26 is still here taking a break.
xla @1024x48 is ok with AMSDM7 512+fs
I did get AMSDM7EC 512+fs at some point and took a screenie when it was stock.

I may have been heat soaked last night too as temps were creeping up to high 60’s and had a couple blue screens the last couple sessions. I loaded defaults and started over on the AI again thinking maybe I didn’t do it right originally. I never loaded default setting and did the Cinebench test and reboot as instructed in the guide. (First time playing with AI Overclocking and only second build since 6700k many years ago.) I only enabled AI and went in and messed about and later had a blue screen, rebooted and did Cinebench test and so on and getting random blue screens before.

We’ll see how it goes in a bit with the new AI training today.
I think xla, ext3, hp@1024x48 AMSDM7EC 512+fs will be stable goal with igpu

Would you happen to know if a beefy 3 slot like a 3080/90 be needed for ASDM7ECv2 pcm2dsd 512 and sinc-Mx or would a small form factor 3060 be enough?

You should be looking at the cuda cores and vram.

I updated to the latest 4.20.2 last night and I am back stable on xla @1024x48 AMSDM7EC 512+fs

Sorry, I forgot to answer the other question. I do convo and peq because I didn’t make it myself and the convo is from Mitch Barnett with a neutral target but I like a bit more bass. So, it’s just a minor .75db bass shelf on an otherwise amazing sounding filter.
