[FFmpeg-user] FFMPEG loudnorm - linear normalization

[CMG DiGiTaL]

hi,

About loudnorm normalization: Normalization in Dual-pass mode.

Rules for normalization to be linear:

1 - Values entry:
    LUFS_TARGET (user entry)
    LRA         (get input file - Pass 1 loudnorm)
    TP_TARGET   (user entry)
    THRESH      (get input file - Pass 1 loudnorm)
    OFFSET      (get input file - Pass 1 loudnorm)

2 - The destination LRA must NOT BE LESS than the source LRA:
    LRA_OUT >= LRA_IN

3 - The destination TP must NOT BE GREATER than the target TP:
    TP_OUT <= TP_TARGET

If these conditions are met, normalization will be done in linear mode
and, if there is any divergence, normalization will be done in dynamic
mode.

These rules are never met... I normalized more than 20 audio files and
in none of them the linear rule was executed, only the dynamic rule!

In all my FLAC audios, the destination LRA's are always lower than the
source LRA's!

Has anyone managed to do the normalization in linear mode... what do I
have to do to get linear normalization?

thanks
Clamarc
