Comment (by Aaron):
Replying to [comment:1 Marton Balint]:
> The 100ms actually comes from the way momentary loudness is calculated,
which is using 400ms sliding windows with 75% overlap. It is defined in
the relevant papers. So something other than this might be possible, but
would not be standard compliant... Therefore this likely won't be
implemented.
Yes, but ffmpeg ebur128 is based on https://github.com/jiixyj/libebur128/,
which has the ability to set loudness window. So it would be nice to be
able to customize it.
