fantastic patch here i got to say can i ask exactly what modifications you made? cause even at 320kpbs -q0 i can hear a difference with your version i couldn't with my airpods.. but then tested with focal lensys pro studio headphones and you can really notice it then even at 320kbps. i mix and master music for a living and your patch version might be the best quality mp3 ive ever heard atleast for CBR anyway is it safe to use to this version? cause i want to start using it going forward and this...
interesting find is this a windows only issue by any chance? just tested lame 3.100 320kbps at -q4 and -q0 using a macbook pro m4 and the -q0 version sounds way better than the -q4 - not easy to tell but its noticeable
