I expanded my old Bash script a bit. It runs ViSQOL-based quality and compatibility tests for Codec2-mod vs. vanilla Codec2 (3200 mode), including cross-encoding between the two (this is the new addition).
Here’s the script: https://github.com/M17-Project/Codec2-mod-eval
You need to provide a set of WAV files for the script to work on. Using an English speech corpus such as LibriSpeech or any other from OpenSLR is a good idea.
Have fun!
