nVidia CUDA GPU computing PC FIR - Page 5

Any further advance with your cuda based fir program? Would be great if there is....

I'm reaching the limitations of brutefir as it doesnt want to play ball with the latest versions of netjack2 (look it up if your into having a seperate linux dsp box and the idea of multiple soundcard clocks keeps you up at night)....

Nothing for this project (for, HDMI output)

I bought Atmel NGW100 and thinking to use it as output device.
8ch PCM data packet -> NGW100 -> ALSA -> AC97(44.1kHz) -> FPGA -> 4 way I2S.

it will take some months to complete

Any progress on this front?

I believe Klein and Hummel has adopted FIR technology for some of their more expensive studio monitors and I might go that way but the price is very high. Is there a solution we could rig up ourselves?

Is there anybody using Cuda FIR based crossover on Linux?

KOON3876 · 13th June 2010, 12:54 AM

progress or changes: I made ASIO output and so far satisfied now.
on Linux: ASIO can be used on Linux? then some possibility..

That's awesome... sound processing in the videocard

ASIO is a win32 api. If someone intrest on GPU powered FIR on Linux, then he/she should choose one of cross platform APIs like libao (Xiph.org: libao: a cross platform audio library) or native ones like alsa, pulse or jack.

you can simulate complete church interor reverbation with 1.5 tflops, in 2.5D realtime, accurate down to 100hz.

also Portaudio : PortAudio - an Open-Source Cross-Platform Audio API

This one is using PortAudio, to HDMI
Multi Amp for Everyone

This is PortAudio to ASIO driver.

So Linux people need some multi channel output, can be used with PortAudio.
