Looking to do a PC XO
Reaktor VS Bidule VS Console - what have you guys used and suggest?
Which VST Plugins do you suggest? The Waves VST looks promising for FIR.
Is there a template that I can load that anyone here created for a good start? This way i could just change the xo frequencies and filter types.
Thanks!

Hi Docks,
The Voxengo Pristince space is imo the best convolution VSt plugin, if you already have the FIR filters to run on it. It has zero-latency convolution, so no added delay, and you can also add manual linear-phase eq to your impulses. It can run 8 parallell filters and you can also cascade filters.
For minimum phase filters check out the demo of MAX/MSP, you can do anything with it and make standalone applications from your setup. The demo is 30-days fully functional and the application is relatively easy to understand if you have a little filter/dsp knowledge.
I am very experienced in MAX/MSP, so if you want to try this I could make you an example patch.
Also you could check out DSP Crossover for PC. Frequency Allocator.
Ths is very nice but has high latency (+- 100ms) which can be a problem for HT use.
greets,
Kees

Hey Kessito thanks for the reply!
When you say IF i have the FIR filters to run on it, are you implying FIR filters for Voxengo? or that they are included?
What type of FIR VST do you suggest?

Also have you tried these?

Hi Docks,
I know the Waves stuff well (I am a studio engineer) but it is fairly expensive.
The Voxengo is just a convolution plugin, which means that it can run FIR filters as impulse responses (google impulse response correction for more info) if you have them.
What do you exactly want to do? just EQ and X-over or more advanced corrections?
If you just want to do EQ and X-over than I would suggest the Thuneau plugin.

In terms of a VST host, I settled on Reaper which struck me as a great balance between a conventional DAW and a prototyping/experimental environment. I like the JS scripting setup as a development env for playing around with things.
For FIR plugins, my intent was to go with Voxengo. They have 2 routes you can take. Pristine Space is an 8-channel all-in-one VST, but they also have the Analog Flux suite which includes a 2-channel convolver; on the Acourate list someone recommended this approach as it let you run multiple instances to get as many total channels as you want.
Kessito's comment about "if you have FIR filters" strikes at the heart of the matter though. Things like Waves LinEQ or even Thuneau Allocator are self-contained ways of generating the transfer function as well as performing the FIR convolution. Straight convolution engines like Pristine Space just do the convolution - they don't help you figure out the transfer function. So, if you're figuring out the transfer function via some other means (Acourate or custom programming) then the Voxengo plugins are the way to go. If you are expecting to be able to simply 'draw' a crossover/transfer function setup, then one of the other products is a better idea.

Thanks again for the help guys, I guess im kinda set on the waves plugins because my friend has the setup and I could experiment a bit on his system prior to creating mine.
One thing I’ve noticed is the linear phase multiband compressor has something weird like 2 in and 3 out. How is this creating a 5 band XO? I need 6 channels out minimum.

i would stay away from waves i tried it and found it lacking. Theres a roundup somewhere of testing on waves, fab filter and a few others waves came last. Ill see if i can find it.
personally i use console and fab filter pro. linear phase etc etc etc.
ive also been playing with cuda crossover filters slopes to 96db/octave ( graphics card runs the algorithms)
crazy processing power but still fairly early in its development.

if you want to play with 120db / octave filter have alook at the engineers filter here btw most of these are free

I really think im missing something. When I visualize using a FIR VST formy XO I think of inserting a module, have 2 in then from 1 to 6-10 out. Specify my XO frequencies and db filter rate etc then have it output each of those bands to the output channels.
How does this convolution stuff work compared to that? Does it use a module per driver/output? Can someone give me some sort of friendly screenshot walkthrough. I've wiki'd convolution and see how it integrates into creating an XO but it's really throwing me off as i just expect to move around different bands for a XO. I did try LinEQ but dont see how that can be a XO, does it take a module per driver??
Does this mean LinEQ would be my XO AND EQ?

If you want to do an XO and EQ solution with EQ plugins alone, you can do that. Use one stereo EQ per driver pair (one for woofer, one for midrange, one for tweeter....). You can also use one EQ per driver if you want to EQ left and right channels separately.
I would stay away from Waves LinEQ. I've used it myself, but it sound harsh. Its also troubled with severe impulse response ringing.
In CONSOLE it may look like this:

I've used Bidule, Console, and Reaper. Settled on Bidule as all I needed was a VST patch bay and Bidule played nicer with my audio interface's drivers (Saffire 40) than Console.
Time reversed IIR tends to be preferable to FFT or FIR as a linear phase option as it's usually lower CPU cost and better behaved at low normalized frequenices. Particularly if you can move the processing offline, avoiding group delay overruns and the need for windowing to handle the resulting disconinuities.

Thanks again for the help guys! Im trying LinEQ a bit more tonight seems alright. Also trying Filtrate by liquidsoncs (FREE BTW!!) also seems neat. My friend showed me voxengo pristine space as well... it looks very promising.
Here's the million dollar question - how do I find my transfer function????

What kind of time reversed IIR VST are you suggesting ? or experienced ?

jcga, I've replied in another thread as this one is scoped to FIR.
Most people seem to do FIR filter design in Octave.
