Thanks everyone,
sorry for the late answer, I had a combination of email client trouble
with Christmas stress among other things.
It would be very nice if at some point youtube would use such a system.
It's rather common today that people use youtube playlists instead of
local music. This could at least solve the problem of different volume.
Anyway, I won't be implementing replaygain at this time, but I still
think it's worth doing. Maybe I'll pick up the idea some other time or
someone else does.
For the project I decided to go with the ecasound GUI. The plan is to
write the GUI using JUCE. The minimal set of goals is, well, minimal,
but I have a few ideas, I'll see where to got from there. No idea how
usable it will become. Ecasound sure could use a GUI other than the Tk
thing nama provides. Imho ecasound has also become more interesting
with the recent addition of LV2 support.
Thanks everyone for sharing your thoughts,
I wish you happy holidays.
Regards,
Philipp

No it does not. "Momentary max" did not fit in the line w/o line break

For comparison, ebur128 reported:
Loundness-range 19.1 LU; Peak 6.7 LU for the Chaplin movie.
and
Loundness-range 11.3 LU; Peak 15.3 LU for the youtube video,
?? ebur128 does not report anything called 'Peak' in LU. The relevant values are the first two:
'Integrated loudness'
and 'Loudness range'. The first should determine any gain
correction, the second can be used to decide if some com-
pression would help.
The last two, 'Momentary max' and 'Short term max' (I guess
one of these is what you call 'Peak') are for information
only and should not be used for the purpose discussed in
this thread.
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!
