I have some downloaded files that seem odd in terms of what I had to do with XLD to convert them into Apple Lossless to use in iTunes (on a recent iMac with High Sierra).
(XLD was not able to simply open them, and I had to use an alternative procedure where XLD said it was a PCM file of some sort with 44.1 rate and some other things I did not recognize...)
I was finally able to get these files converted into files that are designated with an .mp4 extension. But are they really mp3 and disguised?
I am wondering if there is a way to check and see what they really are? I have not imported them into iTunes yet. But I could use iTunes, or maybe XLD can do this?
or is there another freeware program that can do it?
