I changed filter to depend on libmysofa library in latest master, and also plan to add native filter with slightly complex syntax which would have same functionality.

So you are free to fetch latest ffmpeg and compile and try.

I've tried: -af sofalizer=sofa=C:\Users\User_000\Downloads\ClubFritz6.sofa:type=freq:radius=1 -af sofalizer=sofa=C:/Users/human_000/Downloads/ClubFritz6.sofa:type=freq:radius=1 -af sofalizer=sofa=\Users\User_000\Downloads\ClubFritz6.sofa:type=freq:radius=1 -af sofalizer=sofa=ClubFritz6.sofa:type=fr...

You can only use one -af.

Try this:

With latest FFmpeg I can do this:

I guess you need hidepth h264 build linked with ffmpeg.
Otherwise you are forced to pipe to 10bit x264 binary.

Also trying to download your XMA converter I get report from google its infected by virus.

Please go away.

Is there documentation of format for over 30000 files you have?
What exact steps you do?
I can add support for such files if I know some basic info like:
Where one can gather sample rate, number of channels and others?

FFmpeg supports XMA2, but how it could support headerless formats like you posted. is different and off-topic problem.

Please upload/provide somehow files that do not work for you.
