That last 'Signal Max' comparison does seem to confirm that
normalisation has occurred.
That is different than the results on my system, even though I used the
same SoX command line you showed before. I don't know if that implies
some difference between versions of SoX, or different compile time
options, or different versions of sndfile-lib installed on my system
(Fedora 33 just for info).
sox-14.4.2.0-29.fc33.x86_64
sox 14.4.2-3ubuntu0.18.04.1
libsndfile-1.0.28-13.fc33.x86_64
libsndfile
1.0.28-4ubuntu0.18.04.1
Not vastly different here (Mint 19.3)
I am a bit surprised that change gain would be a
default behavior,
definitely not what I would expect from just attempting to change the file
format.
Me too. Hence my misconception in the thread title. Happy to know what
was happening and I'll probably use normalisation anyway, from now on.
I'm not sure how I would find SFC_GET_NORM_FLOAT which has a page at:
http://www.mega-nerd.com/libsndfile/command.html#SFC_GET_NORM_FLOAT
Could that setting be making the difference?
