* priority: normal => wish
* summary: Set a sliding window with a value other than 100 ms => Set a
sliding window with a value other than 100 ms in ebur128 filter
Comment:
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.
