I have been transferring and converting my files to a portable hard drive using the drag and drop function synch handheld option so for use in may car successfully for quite some time. I had previously been converting to mp3 for car use but my new android head unit is capable of playing FLAC natively. It however, doesn't play high res files reliably so I need to down sample some of my FLAC files to 44.1 or 48 KHz.
So I need JRiver to down convert only the high res files and not re-encode the normal FLAC files but Im struggling to find a way. Any suggestions?
