Hi!
After assembling the various mp3/ogg for a specific program, I ran into a
problem that I had not foreseen while recording the various elements of the
show. (All elements were recorded at approximately the same db level.)
Unfortunately, volume levels vary considerably between the jingles
(TOHS/TOHN, opener, closer), the actual show, and end-fillers. My problem
seems to stem from the replay gain when converting from wav to ogg or mp3.
Now for the question: how can I apply normalization to a show's whole block
of individual components, so that the volume would be reasonably close
between all elements?
Is is possible to do so?
Here is a representative sample of a show from 'liquidsoap-mp3.liq':
coc = request.queue
(queue=[
request.create("/usr/local/www/rcr/mp3/announce/TOHS.mp3"),
request.create("/usr/local/www/rcr/radio/current/mp3/announce/opener/opener-coc.mp3"),
request.create("/usr/local/www/rcr/radio/current/mp3/coc/today/today-coc-32.pls"),
request.create("/usr/local/www/rcr/mp3/announce/CLOSER.mp3"),
request.create("/usr/local/www/rcr/radio/current/mp3/coc/today/today-coc-end.pls")
])
scmp3 = fallback([coc,security])
scmp3 = crossfade(start_next=0.7, fade_in=0.2, fade_out=0.2, coc)
The bottom line refers to a dynamically generated (from a database)
playlist,
a sample would be:
'today-coc-end.pls'
[playlist]
File1=/usr/local/www/rcr/mp3/announce/Upcoming.mp3
File2=/usr/local/www/rcr/mp3/music/Genuis/Timeless/odd/Eric_Genuis_-_
Timeless_-_03_-_Wisdom_Lost.mp3
File3=/usr/local/www/rcr/mp3/announce/Donate.mp3
NumberOfEntries=3
[/playlist]
I am so close to getting this on-line, and now this . . . help?
Thanks,
Andre
