Cortesía del forero Jimix, me ha hecho llegar un enlace que me ha puesto los pelos de punta y los dientes largos …
http://www.diyaudio.com/forums/showthre ... did=120463"Real" FIR for 4Way requires huge computing power.
So I selected nVidia's "CUDA" Graphics Card computing.
By Cuda, I think fan less PC can do 88.2k/24bit, 8192 Taps, 4 Way FIR channel dividing at real time. (with fan less video card, 8600GT / fan less CPU, Athlon BE)
These knowledge are required to reproduce CUDA FIR at your PC.
(1) FIR calculating, mathematical knowledge
(2) C programming
(3) nVidia graphic card, newer than 8000 series
(4) nVidia CUDA SDK programming
(5) nVidia CUDA compatible OS, and Driver

Cuando me lo ha contado, no me lo podía creer …
Un crossover FIR multicanal usando un procesador grafico de nVidia ????
Imposible !!! … o quizás no …
Sin embargo, lo más sustancioso está por llegar …Complete FIR Crossover can be Audiophile's dream, by it's sharp filter and linear signal phase.

Digital Room Correction. FIR Parameter generater can process 8192 EQ points (5Hz accuracy) for digital room correction.
There are no IIR or phase modification. FIR coefficient parameter is conditioned by EQ gain at each frequency.
I have not been so much impressed by DRC, by TacT RCS. was it IIR and I felt much phase rotation?
Alguien se anima ???
Saludos.
