Recently I'm looking into ways of doing audio loudness normalization and
came across ffmpeg filter `loudnorm` .

According to EBU R128 standard:  "measurement shall include a gating method
as specified in ITU-R BS.1770" which requires a momentary measurement which
is 400ms instead of the shortterm one (3sec) used in the loudnorm filter:

Did I miss  something here? And is there a way to make the change in ffmpeg?
