 * 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.
