Hey hey everyone,
I'd like to do some loudness metering on the commandline. I've seen a tool
r128gain which looked promising, but doesn't compile. I'd rather not go and
figure out how to fix it right now.
Is there any other tool, that I may use to get: LUFS of a whole track, dynamic
range and peaks. I reckon more wouldn't be feasable on a terminal.
Any tips are welcome. Thank you very mmuch.
Ta-ta,

New subject: [SOLVED] Commandline EBU R128 metering
Hey hey again,
sorry for the trouble. I found that ffmpeg can do it, although I had to edit
the configure script to build the ebur128 filter.
Should anyone else have problems getting that and other filters compiled: go
into the configure script and search for you filter name. You should find
entries ending in deps, e.g.:
ebur128_filter_deps="gpl"
remove the gpl from within the double quotes and run ./configure again.
Ta-ta,

Thank you Chris! I hadn't even considered it, since the few of his small tools I tried
were purely GUI driven. This is excellent!
Also thank you Fons for providing such great software with and without CLI support! <3

I think ffmpeg has features to adjust an audiofile to a
certain loudness, though I didn't look into those in particular. There is an ebur128
filter and something about correction/adjustment. Sorry for being so vague.

Seems that the thing to use would be bs1770gain.

If you have already checked the current level with ebur128, you can use
sox to adjust up or down by a gain specified in decibels.
You should also check whether sox now includes a measurement using R128
standard, possibly the adjustment could be performed automatically with
one command. I don't have time at the moment to check the sox
documentation, there are so many command possibilities with sox I always
spend a long time just searching the command line options for the
combination that does what I need. I do know for sure that simple gain is
one of the simpler operations, so manually measuring with ebur128 and then
using sox to apply gain should be reasonably easy.

ebur128 which is part of the ebumeter-0.4.0 package will do what
you want.
wget kokkinizita.linuxaudio.org/linuxaudio/downloads/ebumeter-0.4.0.tar.bz2

I noticed the download page at kokkinizita.linuxaudio.org still links to
the version 0.2 tar file, and the README file does not list any changes
for version 0.4.
I notice that there is an oversampling peak detector in ebu128 now, is
that the primary difference?

Yes. In the gui version, the peak indicator will flash yellow
if there is a peak above -1 dB FS, and turn red permanently
for any peak above 0 dB FS. Click to reset. The signal is
upsampled by 4 for peak detection.
