Thanks for your prompt reply! :-) > I forwarded it as bug (or rather feature request) #58504. Great! I managed to better understand the Perl code that handles the interaction between normalize-ogg and normalize-audio. I have just prepared a patch that fixes the bug. I am attaching it to this message. It's simple enough and should therefore not be covered by copyright. In case it turns out to be copyrighted, it's released under the same terms as normalize-ogg (that is to say: GNU GPL v2 or later). With my patch applied, I get: $ normalize-ogg -a -7.5dBFS --tmpdir /dev/shm -b -n -v -v *.ogg Decoding track01.ogg... Decoding track02.ogg... Decoding track03.ogg... Decoding track04.ogg...

Please note that I had to pass the "-v" option twice, since normalize-ogg adds the "--frontend" option, thus decreasing the default verbosity of normalize-audio. By the way, maybe the same modification could be applied even for the code that deals with the "not mix or batch mode", around line 765... Please test the patch and forward it upstream, if you agree. Thank you so much for your kind help! -- http://www.inventati.org/frx/ There's not a second to spare! To the laboratory! ..................................................... Francesco Poli .
