GPU Impulse Reverb VST is an effect plugin that calculates convolution reverbs by using your graphics card as DSP for realtime reverb calculation with a CPU usage of near 0%. Any consumer graphics card that supports OpenCL (NVIDIA / ATI or others) can be used without any need for other specific hardware. All common VST hosts are supported, such as Cubase, Nuendo, Reaper, Fruity Loops and others.

A public demo is available, free to try for everyone.

Features include…

* Low latency, only one ASIO block size
* Supports Stereo & True Stereo processing (quad-channel wav files required)
* Supports 16, 24 and 32 bit responses
* Supports as many instances as your GPU can handle
* 2-Band EQ
* Adjustable Attack/Release & Length Envelope
* File Browser for easy access of IRs
* …and much more

Does this work on mobile GPU units on laptops?

Hi Nils,

Very cool! Unfortunately I have Ati Cards in both of my PC's so I can't test it

. Didn't you make another plugin a while ago wich also ran on gpu's?

Thanks for the plugin, but Reaper doesn't load it.

is this using CUDA? will absolutely not run on a 7 series card?

Nils Schneider · Post by **Nils Schneider** » Sat Jul 26, 2008 4:24 pm

Yes it is using CUDA and unfortunately won't run on any 7xxx or Radeon card though...

Nils, I have an 8800 GTS card and did try to load your plug-in, but could not get it to work.

do I have to install additional cuda software? or a special driver pack?

maybe you need to install the right video driver and (I guess) the right cuda toolkit

This ain't for me. Stick to cpu so all can use your plugins.

Oh god damn it I'm on a GeForce FOAR.

But yeah, that is quite a task you've pulled...GPU doing other processing work. Wouldn't it interfere with display processes?

I got it working ok with wavosaur.
No additional software was needed in this case (9600gt with recent drivers)
Hopefully later versions work in reaper too?

I want to create something *new*, not reinventing the wheel again

The problem seems to be that the installer has to copy the cuda DLLs to the system32 dir instead of the plugin dir, I'll release a new version soon that will fix this issue.

If anyone wants to try it out, copy the cuda*.dll to the system32 dir of windows.

Or just wait for the new version

I have a Geforce 7600 so I can't use it, but I applaud your endeavor! Good luck!

Could you give me some details? How much CPU did the plugin use (I hope nearly nothing?). What GPU usage did you have and how long were the impulse responses that you used?

I've got 67% GPU usage for a 17 second IR, CPU usage below 1%
