Yup, you can have a look at the dev branch on github. There is a lot more meta data compatibility and consistency. The rewrite was to keep this all easy to test and modify. There were way to many buggy releases in the past. Loop data maintaining the right times when changing sample rates was the entire reason I couldn’t just copy and paste all meta with ffmpeg. Now we parse and write it all manually. After this is done I’m working on the GUI version that will be even more powerful and easy to use. CD ripping too!
