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.
