Hi all,
Has somebody any experience with loudness audio normalisation?
I personally use it in case of BD / DVD authoring to normalise all the
sounds.
It seems to be the most recent for broadcasting, as the mean audio level
does not analyse the audio frequency spectrum.
Loudness seems to be the closest to the human response.
ffmpeg has this filter: (
https://ffmpeg.org/ffmpeg-filters.html#ebur128-1)
ffmpeg -nostats -i input -filter_complex ebur128 -f null -
"I" gives the value of the integrated loudness. The optimal value for
broadcasting seems to be -23 LUFS.
This filter does not give any indication of the peak, so the classic
analyse would be necessary to avoid saturation.
Anyone thinks that this analyse could be useful for DoM?
