Equalizer APO, REW and Rephase WOW!

Yes, textbook IIR filters won't work for this type of filtering.

There's Berchin's FDLS arbitrary filter design algorithm which could be helpful in designing the IIR filter(s) for the needed EQ curve.

Berchin, Precise Filter Design, DSP Tips & Tricks, Signal Processing Magazine, 24, 137-139, January 2007

I've used the Matlab implementation few years ago but didn't find it anymore.

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.

Hmm... have you checked this version?

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.
