You all got a valid point… it’s just that mileage varies and x codec will sound better in y combination. If I remember right, AAC on Android is at times implemented differently than on it’s home Apple: The encoder would work with smaller bitrates to save battery. There must be a special synergy for max bitrate LDAC to sound worse than AAC, indeed. All in all my post is about being open minded and giving you the option to use a thing, rather than finding out what codec is universally the best: You virtually can’t, can you?
You’re right. Syncthing isn’t a backup tool per se and the devs even tell you that in the FAQ. But forgive me if I did preach about it anyway, because you can enable file versioning (keep old and deleted files on each host) which kind of makes it backup incase something bad happens? Anyway it is my set and forget solution for Linux, Android and Windows. If you could recommend me a alternative that ticks these boxes I’d appreciate that. :)
