zircon Posted August 22, 2008 Share Posted August 22, 2008 http://www.kvraudio.com/forum/viewtopic.php?t=222978&postdays=0&postorder=asc&start=0 It's not even theoretical - this is an actual, working VST plugin that runs off your video card's processor! It's a convolution reverb too. Downsides include very high latency and limited compatibility (works only on Geforce 8+ series cards with the latest Forceware drivers) plus simple design and unoptimized code. However, it's still incredibly awesome, and the programmer admits that he doesn't know much about convolution reverbs and hasn't bothered optimizing to begin with. Imagine, being able to run 20-30+ VST plugins on your graphics card alone - a gamer's $200-300 "high end" card, which is pennies compared to high-end DSP cards, could provide far more flexibility and power.

PrototypeRaptor Posted August 22, 2008 Share Posted August 22, 2008 But would the dsp plugins that go along with the dsp cards work? I thought that the reason people bought the cards was for the awesome, better than vst sound, eg: compressors, eqs, etc. Would the plugins developed for use with the gpu be just as good as, say, UAD's? Here's to hoping...it would be really cool to have an alternative to freaking $700 entry level dsp cards. (I know I can't afford one...)

zircon Posted August 22, 2008 Author Share Posted August 22, 2008 No, plugins developed for DSP cards will only run on those cards. Plugin quality for GPU would be entirely dependant on who is doing the programming. However, it's still exciting because DSP cards are generally woefully underpowered and overpriced.

The Vagrance Posted August 22, 2008 Share Posted August 22, 2008 Sweet! I knew there was a somewhat justifiable reason for putting a Radeon 4870 in my new production PC. Quote Link to comment Share on other sites More sharing options...
The Pezman Posted August 22, 2008 Share Posted August 22, 2008 GPU processing is on the way in, brought about by the whole multicore trend that was brought back. I'm sure, in the not too distant future, there will be few programs which don't rely at least partially on GPUs. That said, this is a great start.

analoq Posted August 22, 2008 Share Posted August 22, 2008 It'll be interesting to see how this technology plays out. I know Apple in particular is making headway by integrating OpenCL into their next operating system. Good things ahead. Quote Link to comment Share on other sites More sharing options...
dannthr Posted August 26, 2008 Share Posted August 26, 2008 We definitely need to move to more flexible processing and this is only the beginning. Although, GPUs I think are optimized for calculations like matrix math, which I don't think are used in standard DSP apps, but could be very nice for something like VSL's MIR tech which has convolution simulation for placing instruments in a 3d virtual stage.

Drack Posted August 26, 2008 Share Posted August 26, 2008 VST on CUDA/GPGPU? Looks like a fantastic idea. We won't be doing heavy graphics while making audio, so if the GPU is practical for effects processing, this looks promising. Quote Link to comment Share on other sites More sharing options...
Argle Posted August 28, 2008 Share Posted August 28, 2008 This sounds like an amazing idea! Quote Link to comment Share on other sites More sharing options...
