But that's the point, I need to *mix*all segments, not join/concatthem.

I'm actually trying to prefend volume reduction. I only want to mix all
segments.
(I noticed I forgot to attach the Avisynth script I used years ago. Attached
now.)
In the Avisynth script I align all segments (with sample precision) and mix
everything with full volume: MixAudio(clip1,clip2,1.0,1.0)
ffmpeg.exe -h filter=amix
[...]
weights <string> ..F.A.... Set weight for each input. (default
"1 1")
I figure "1 1" does the same as MixAudio(clip1,clip2,1.0,1.0), doesn't it? But
amix still reduces the volume dramatically.
Let me ask you this: How can I do MixAudio(clip1,clip2,1.0,1.0) with ffmpeg
leaving the volume completely untouched?

You mean the adelay filter, right?

Please see my first post.

Well I'll be darned. A typo. Thanks!
That solves that problem, but the volume issue remains.
