Package: normalize-audio
Version: 0.7.7-15
Severity: normal
Hello and thanks for maintaining this nice program in Debian!
I wanted to run normalize (in batch mode) on a group of audio files
with the --no-adjust option, in order to analyze the files, without
altering them in any way.
I can do this on a group of .wav files with
$ normalize-audio --amplitude=-7.5dBFS -b -n -v *.wav
and it seems to work as intended.
However, if I want to do it on a group of .ogg files, I get
per-track info, but not the standard deviation, average, or
per-album adjustment data.
$ normalize-ogg -a -7.5dBFS --tmpdir /dev/shm -b -n -v *.ogg

This is weird, since normalize-ogg decodes the .ogg files into
.wav files and then runs normalize-audio on them.
Hence, I would expect the same output...
Yet, if I manually run normalize-audio on the decoded files,
I also get the final data I am interested in:
$ normalize-audio --amplitude=-7.5dBFS -b -n -v /dev/shm/*.wav

I cannot understand why normalize-ogg seems to suppress the
final output lines (which include interesting data about
standard deviation, average, and per-album adjustment!).
I took a look at the normalize-ogg code, but my knowledge
about Perl is just a smattering, and, in addition, it is rusty.
Hence, I failed to understand the tricky part (with exec()
and pipe handling, I think...).
How can normalize-ogg be fixed to show all the output
of normalize-audio?
Please fix this bug and/or forward my bug report upstream,
as appropriate.
Thanks for your time!
Bye.
