yeah i wondered about that, as the same release notes mentioned nothing about AVX on the darwin/cocoa notes further down. yes, the 13MHz usb clock is the main clock for mcu/DSP/USB, but with the 2 dedicated audio clocks for 22x and 24x integer audio clock and 8 x 32/192 opt 4 x 32/384 i2s out on RJ45 or pinheader.

it can act as slave or master, but different setup needed for each. its set to master by default, quite an impressive board (if a bit large due to fairly large number of dedicated choke input power supplies) i'll probably make a post in the weeks to come, I've only recently got the mac mini which enabled me to use it and NO, for others reading, i have nothing to gain from its sale, I was simply contacted due to having a fair number of sabre dacs and apparent knowledge to set them up

on that note, it really its incredible the powerhouses you can get for little money these days; traditionally i would buy somewhere in the mid-high end of the mac lineup, but i could not think of any justification for it this time around given i don't game and don't do so much 3d modelling/design anymore.

I tried to open VST_AVXFIR.dll in my VST Host (Art Technika Console) and i see anything ...

Hi Jean
Please check
(1) OS: Windows7 SP1
(2) CPU: SandyBridge, Core i3 or more
(3) Download Details - Microsoft Download Center - Microsoft Visual C++ 2010 Redistributable Package (x86)
Microsoft Visual C++ 2010 Redistributable Package

and, are you already using another VST? if so, put my VST dll into same folder.
if not, VST host should be configured for which folder to find VST.
good luck,

I already using filtering VST plugins
My OS is XP
My CPU is an i7 860
So do you mean that your VST pluging could only run with seven and a sandybridge CPU ?

KOON3876 24th October 2011 11:10 PM

unfortunately, yes, Intel AVX is available on limited CPU and OS, updated 2011.
You can try VST_SSEFIR. This is slower than AVX but will run on i7.

mike34300 24th October 2011 11:30 PM

I tried VST_SSEFIR , it runs on my computer with only 11% CPU per Plugin.
Thanks for your help i will compare it to my VST Plugin : PLParEQ (Refined Audiometrics Laboratory).

KOON3876 24th October 2011 11:50 PM

Thank you for trying:)
When I used CUDA version on Core2Duo, 13% plugin x 3 caused underrun.
(depends on VST host? I'm using Reaper)
my VST just calculates very straight FIR. If you're programmer please take a look for source code.

KVR: Refined Audiometrics Laboratory PLParEQ - Virtual Effect
...oh. $1,000?

mike34300 25th October 2011 12:04 AM

Yes it was the price ...
2 x PLParEQ is running at 30 % CPU at 16384 samples , 32768 samples is possible but at 60 % CPU it is not very stable.
Unfortunately im not able to program , i compared it at your plugin only some minutes and it seems more or less similar.
The x-over is at 200 Hz , the result of the comparaison could be different at other frequencies ...

Hi Koon.

I find all that Windows implementation pretty complex.

On a nice rt-Linux running brutefir lots of issues could be
much easier. Somebody would have to port brutefir into
Cuda-space though. But even that wouldn't be required. It's that fast.

The main problem under Linux is the multichannel interface.

If exau2i would support Linux even at lower sample rates and no DSD,
I'd place an order today. ;)

BTW: What do you prefer soundwise? Your sd-card player or the PC setup.


KOON3876 25th October 2011 05:37 PM

Hi Soundcheck,
FFT based PC crossover setup on Windows is easy.
maybe there will be another free VST (FFT EQ) and VST host.
bruteFIR is FFT based, algorithm O(N x log N). not required to be faster.
straight FIR algorithm is O(N x M), so large N,M requires much computing power.

for exaU2I now there is Mac driver, please ask exa065 for source or Linux.

? soundwise :confused:
