Hi, when I first got into this personal audio thing, I had a Sony W995 phone (loved it)
and used Sony Media Go to transfer music to phone.
I chose the highest rez possible then that was AAC 320, I have a massive library
of these files, but looking at them using Windows Explorer they are .mp4 files not AAC.
None of my players (Nokia 8, Iphone5, HM-801,Studio V, HM-601) will play them
I have re ripped most of them as FLAC or WAV now but it seems a shame to delete them
So can I convert them to "proper" aac without losing quality?
Or is there a cheap player than plays these files? I would expect another Sony
machine to be able to.
Or do I just press delete?
