Several years ago I became aware of a foobar2000 digital crossover component written by Francois Bourdon (http://xover.sourceforge.net/).
It works with foobar2k, has many features and is very stable; but, it does not do two of the things I was looking for, specifically, LR4 crossovers and some way to do BSC or otherwise do base extension.
I then purchased Allocator Light, later upgraded to Allocator (http://www.thuneau.com/products.htm). This was better in that you can load driver files; but, I found the interface awkward and it did not work with foobar2k. It does have a capability to support Winamp, although like most players these days it's doing a lot of stuff I'm not interested in. It is fairly stable.
I have used both UE1 and UE2. UE2 is fairly stable; but it does not work with foobar2k, at least directly.
I can not hear any benefit to the phase flattening.
I have used some of the rerouting software with mixed success.
Having to move my Rockey around is an annoyance and the standalone version is fairly expensive.
I decided, about eight months ago, to write a component for foobar2k myself as a retirement exercise, separating the xover and the analysis.
I considered modifying Francois Bourdon's program; the source is available.
That was going to make the job much harder just to preserve a lot of capability that I think most people would not use.
More than forty years ago I programmed a lot of FORTRAN.
That left digital filtering, C/C++, Visual Studio 2010, Windows API, dlls and foobar2k interface to learn.
I have two programs which are both functional, although the analysis tool is not user friendly.
One is the foobar2k component with inputs for frequencys, gains and channel assignments (which allows muting); the other is an analysis tool
which takes FRD (three column text) files and applies filters and gains to allow the selections for the foobar2k component.
The analysis tool does 2, 3 or 4 way speakers. The crossover is only Linkwitz-Riley fourth order (three way at the moment, no time delay)
and it has a second order low shelf filter. I initially did this analysis using SE.
I'm hoping to eventually make this available to the DIY community, who will generally not have SE, so I'm creating the analysis tool to go along with the crossover.
Users will still need to make driver measurements and apply baffle effects.
I have the crossover component operating with my family room speakers.
They use two RS225 woofers, a ZA14 mid and a RS28F tweeter per side.
The computer is my oldest operating computer. It's a about 1.6GHz AMD.
It uses about 7 percent of the CPU. The amplifier is a fairly low end Onkyo which has the capability to use direct inputs
and do volume control for all. I'm sure my ears are not the most critical; but, it sounds terrific to me.
I have also used it with dual RS180s, SS10F and a NT1 with similar results.
I would like to find a couple of people who are foobar2k fans and would try it and provide feedback.
I can supply my analysis tool. It is command line driven and not tolerant of bad input.
SE is probably easier to use for those who have it.
PM me if your interested.
