I'm trying to normalize (and or compress) around 100 .ogg files which have audio level really too low.

I know that by hand I can use Audacity ... but that will be too much clicks! Instead I was looking for a tool which can be used in a small script (or with --recursive).

Just tried to look in man oggenc, man ffmpeg, with no success yet...

Thanks!

Why did you include "compress" in your question? Could you add a couple of lines to your question or answer to clarify that? –  user25656 Aug 13 '13 at 2:12
    
And is there any significant quality degradation? –  user25656 Aug 13 '13 at 4:48
    
@vasa1: In my tests I found that compression would give better dynamic to the sound, mainly for those who are mainly low level and with one peak. I finally adjusted (with Audacity) the 3 files with those special peaks and run the normalization on all the files. Since the original file was really low, I added -a -15dBFS. With that option, I don't hear quality degradation. –  samb Aug 13 '13 at 6:39

Finally, I've found the package normalize-audio which provides the tool normalize-ogg. So I just had to run :

for audio_file in *.ogg; do
    normalize-ogg $audio_file;
done
