Hallo!

>>> Do you just want to adjust the loudness between multiple files?

I meant, if you have longer files with a high loudness range, maybe you
should also adjust the loudness of different regions within your file -
but I guess it's not the case ... ;)

> I tried it on a couple of files:

That's great - now you only have to bring all your files to the same
loudness!
For example, let's say you want all files to be at 13 LU.
You can apply a simple gain on all files:
-0.7 dB for the first file (13.7LU), 0dB for the second, +7dB for the
third (6LU) and so on ...

I think you can do that with sox - and maybe it's also good to use an
additional limiter (at -1dBFS or lower), to avoid clipping!
AFAIK sox has the compad effect, which can do that ...

Have a nice weekend,
LG
Georg
