I really hope you can implement this.
Dolby Digital EX and DTS-ES Matrix tracks cannot be decoded by any PC media player and it would be great if they could be decoded to the proper 6.1 (or 7.1) with EqualizerAPO.

Thanks in advance.

You mean decoded or upmixed?
EAPO receives already decoded streams, my configs are only for upmixing.
If LAVAudio can decode them I might have a look.

LAV Audio cannot decode Dolby Digital EX and DTS-ES Matrix tracks to 6.1, and it is only processed as 5.1.
However, discrete 6.1 tracks are handled properly in 6.1.

The decoding of Dolby Digital EX and DTS-ES Matrix works similarly to Pro Logic upmixing.

An upmixing config for 5.1 to 6.1 in Dolby Pro Logic IIx could probably restore 6.1 to these matrixed Dolby Digital EX and DTS-ES tracks.
