No it does not. "Momentary max" did not fit in the line w/o line break in my mailer :) > The relevant values are the first two: 'Integrated loudness' > and 'Loudness range'.

Thanks for the clarification. So let me correct that: The Great dictator DVD has an Integrated Loudness of 4.1 LU, Loudness Range 19.1 LU. and 'Music for one appart. and 6 drummers' from you-tube: Integrated Loudness: 12.9 LU, Loudness Range 11.3 LU Both are already normalized to 0 dbFS. Checking some more, revealed that you-tube does not actually normalize audio volume automatically: e.g. http://www.youtube.com/watch?v=hJMEvDu0K2E peaks at -16.5 dbFS Integrated Loudness: -1.7 LU, Loudness Range 9.9 LU > Updates of ebur128 will show only the first two, unless > you explicitly ask for the others as well. > > Ciao, > Cheers! robin _______________________________________________ Linux-audio-dev mailing list [email protected] http://lists.linuxaudio.org/listinfo/linux-audio-dev
