AVX based FIR VST, crossover / EQ / DRC and delay

Hi Boris
Hosting FIR processing into ASIO driver / Output Port to Processing Routing
These are solved by Reaper.
https://sites.google.com/site/koonau...-FFT-crossover
Reaper has ASIO virtual driver(ReaRoute, input from player software) and Asio client output.
from foobar or other Player software, Reaper looks like ASIO sound card.
your thought, 2 sound card, has big problem for underrun/overrun. by using Reaper and ASIO, I can process all signals in single clock domain.

'Virtual Audio Driver' Still If you want to try whole processor by yourself..
I posted simple ASIO driver source code.
https://sites.google.com/site/koonau...channel-usb2-0
(1) get ASIO SDK from steinberg, build sample driver by yourself
(2) get koonasio01_20111128.cpp and include in your project, then struggle
(3) change output from FTDI(mine) to ASIO client.
Then you have ASIO in - ASIO out virtual driver.
(4) hook FIR processing in virtual driver. (ASIO driver has buffer copy, like VST)

I realized that ReaRoute is a virtual driver in Reaper as I was typing earlier so I guess Reaper will be able to handle what I had in mind. I haven't tried setting ReaRoute as the default sound card on a Windows system. I guess the only requirement is that Reaper is always open.

Hi koon,

When I try to load your vst plugins into Reaper, I get an error saying that the plugin executed an invalid operation during scanning.

My setup:
Windows 7 x64
Reaper x32
foobar with asio_out plugin
Auzentech x-meridian sound card.

Thanks,
Corey

The plugin will crash if your computer can't support it. These FIR plugins don't do regular CPU processing. You need special processor to run them. There are currently 3 versions using 3 different technologies. Make sure your hardware meets one of these requirements and run the appropriate version.

SSE - the oldest and most available technology. Most current Intel and AMD CPUs support it.
AVX - it's new, only supported on the Intel Sandy Bridge and AMD Buldozer series.
CUDA - this is a technology that allows code to be executed in parallel on the graphic card's GPU thus freeing the CPU. You need a CUDA capable nVidia video card.

I am running the sandy bridge core i3. It happens with the SSE and the AVX plugin.

When I install the microsoft C++ redistributal, it gives me the error. When its uninstalled it can't find the dll file that comes with the installation of it. I would really like to try these plugins.

I fixed it, I was missing service pack 1
