Just noticed this thread. Matlab and C implementations of FDLS are available directly from the author (that's me). gjberchin at charter dot net
Question about Equalizer APO on small/slow Win 10 PC with Voicemeeter.
Can Equalizer APO use more than one CPU core?
On Analysis panel is show CPU usage in % with note "one core".
Is this meaning that it can use only one core?
In my practice I get distortion (missed bits probably) when Voicemeeter CPU usage goes over 25% on 4 core Atom Z8350.
I use Equalizer APO as Voicemeeter plugin to get all running on ASIO and distortion is get when its CPU usage is about 25%, separately Equalizer APO seems not listed as CPU using process.

No, but have I chance to run it on Atom Z8350 Win 10 and with Voicemeeter?
Quick search find Atom Z8350 did not support AVX or AVX2.

Is anyone here using rephase and the convolver engine in equalizer APO to fix the crossover phase issues? I don't think I have ever seen another system that uses this.
This trick allows me to use 1/8 order crossover between my mid-range and tweeters to really pull down that crossover point without any of the strange effects that I would normally get out of an eighth order LR. The rest of the Crossovers on the 4-way system are 4th order LR and phase correction is applied to fix not only the crossover phase wrap but also The Oddities introduced by the ported speakers. I believe the result is really worth it, I've got a chesky recording of a drum solo and it just blows people away.
The difference is very noticeable with the kick drum. I think the phase wrap issues that are introduced by crossovers produce somewhat of a fatiguing effect. This is apparently not an issue with certain kinds of fir filters but the really cool thing about doing the phase correction separately is that you can actually fix the phase issues with passive crossovers or regular IIR DSP crossover such as the ones used in the mini DSP units. Being able to fix passive crossover and port phase issues is really spectacular in my opinion.
Obviously frequency response issues are a much bigger problem and should be addressed first, but if you manage to perfect that then I believe the next step is to address these phase issues.
Sir if you are still watching this thread I would be keenly interested in a tutorial on exactly how you are acheving your results. Thank you for your time.
