For what it's worth, I've found the source code for the mentioned old plugins: https://github.com/p/xmms-gtk2/tree/master/Effect A quick conversion to E-APO config, might look like this (minus the limiting to valid 16 bit values): Voice removal: Copy: L=R+-1.0*L Copy: R=L+-1.0*R Extra Stereo: Change the 2.5 value to adjust the strength of the effect. Copy: AVG=0.5*L+0.5*R Copy: LDiff=L+-1.0*AVG Copy: RDiff=R+-1.0*AVG Copy: L=AVG+2.5*LDiff Copy: R=AVG+2.5*RDiff It seems I ended up mixing up a bit...

Hey Peter, thanks again for the reply! Just to clarify... I had some artifacts (noticeable on some tracks) using my "Mimic Microsoft's/Realtek's Speaker Fill" version, and also using the "original Speaker Fill" from MS/Realtek. The one you mention where the issues might be... it's the "expanded" version of HeSuVi's upmix from stereo or 5.1 to 7.1 (that I included for reference, as a follow up). Notice that I started that config with # HeSuVi's upmix (on my second post), and "mine" with # Mimic Microsoft's...

Hello guys. I just wanted to share some info regarding the use of Equalizer APO (EAPO) and/or Microsoft's (or Realtek's) "Speaker Fill". Before installing EAPO, the Realtek control pannel for my 5.1 onboard soundcard (HDA Audio, codec: ALC662) used to show a checkbox for "Speaker Fill" (when setting the system in 5.1 mode). After installing EAPO, that control disapeared. It seems that that "effect" is not really from Realtek software, but standard from Windows (can be seen in the "Enhancements" tab...

Thanks for the explanations, Peter! Much appreciated! I had assumed that said "Speaker Fill", and the "Loudness Equalizer" enhancements were from Microsoft and not from Realtek, because those two are the only ones that read "Provider: Microsoft", while the others read "Provider: Realtek" when you select them in the "Enhancements" tab for a particular audio device properties. ¯\_(ツ)_/¯ Anyway... I'm very happy to be able to leave E-APO installed both as pre and post-mix... and being able to play around...

As a follow up, I'd like to mention that HeSuVi also has an interesting upmix from stereo AND 5.1, to 7.1. Said upmixes can be found in HeSuVi's matrix.txt and matrix51.txt files, as one-liners. The following is just an "expansion" of those one-liners, just for readability's sake: # HeSuVi's upmix Stage: pre-mix If: inputChannelCount == 2 Copy: L=0.5*L Copy: R=0.5*R Copy: RL=0.3*L+-0.2*R Copy: RR=-0.2*L+0.3*R Copy: C=0.2*L+0.2*R Copy: SUB=0.0 Copy: SL=0.45*L+-0.25*R Copy: SR=-0.25*L+0.45*R EndIf:...
