I would like to do some listening tests for vorbis and opus at different bitrates on my LMDE PC (it is debian based).
Just, I don't know which software can be used to the purpose, can you help me?
I apologize if this is an already asked question, I'm totally newbie here.
When I Google ABX software Linux I get
http://manpages.ubuntu.com/manpages/bionic/man1/abx.1.html
https://lacinato.com/cm/software/othersoft/abx
etc
I just use Foobar2000 under WINE on my Linux Mint v20.1-Cinnamon PC. then you should be able to ABX with that on Linux. I can't imagine you would have any major issues installing Foobar2000 under WINE for LMDE4.
Install wine package;
sudo dpkg --add-architecture i386 && sudo apt update
sudo apt-get install wine
download foobar2000
associate .exe or .msi files with /usr/bin/wine
run foobar installer, create portable installation in the HOME folder
run foobar2000 as needed from that folder.
A web based abx
use 'by file input'
