GPU Convolution Impulse Reverb FX VST using NVIDIA / ATI graphics, 0% CPU usage

[alexirae2]

Thx for your quick response, of course, but what is the minimum latency supported by the plugin?, If the blocksize is small, consumes more CPU the plugin for the cudaMemCpy operation?

[Lyve1981]

@alexirae2 The minimum latency is 64 samples at the moment, the CPU usage is not the problem, but the latency that one memcpy operation always has is a problem so staying at 64 as minimum should be a good value. I'm unable to test it with lower latencies though as my soundcard only allows 64 as minimum so I adjusted the plugin to always use at minimum 64 internally.

cudaMemcpy is not used as I use OpenCL :)

Hey man, great work!, How much latency for the ASIO Driver do you use in this demonstration?, the plugin work at 128, 256 or 512 samples?, Thx!

[Lyve1981]

@alexirae2 The latency is always one ASIO blocksize, so if the asio plugin is 64 samples, the plugin produces 64 samples of latency.

Where I can download/buy this plugin? It is exactly what I need

Pretty nice idea.. Beats buying extra DSP cards

[ladex142]

great idea! DAWs, Plugins, & Virtual instruments should all take advantage of GPU processing....

hey man what´s this song? thx

[Lyve1981]

@petardo41 Moonlight sonata from J. S. Bach

[Hausch13]

@Lyve1981 Ludwig van Beethoven wrote this , bach was six feet under when this was written... as a matter of fact , bach died 20 years before beethoven was even born

@Lyve1981

Moonlight sonata from BEETHOVEN, not Bach.

wow!

have you been hired by a big time plugin company yet?

[Lyve1981]

@andyzweb No unfortunately not yet :)

[mustermaenner]

Unbelivable!I always thought that there must be a way to use the gpu for vst plugins.I hope i can play physical moddeled instruments like pianoteq soon gpu powered!

Spaceimp2001, why do you think software is patentable?

Gpu's are good for massive paralleling proccesses, like filters and audio fx's, like the displayed in this video. But they aren't good for decoding an ogg file, e.g.

Thanks for the info, Lyve1981, and go on!

[spacepimp2001]

If you crack this with low latency, you could have impulses from the complete signal chain from, say, Abbey Road, all running on a low end graphics card. This technology could be massive. There's impulses from instrument bodies and weird resonant spaces and obejects to classic outboard gear and concert halls on t'interweb. Nvidia and Ati should throw large sums of cash at you. And it's still going to be free? You, sir, are a legend.

Nice, where can i buy it?
