®: What file types can the BS4 now read?
. According to the documentation, WMA files up to 192, MP3 files up to 320. If you rip MP3 files with LAME encoding, I find that is a very nice recording that will play anywhere. For years I have used CDEX, a free utility, then sucked them into iTunes for use with iDevices. I dont use iTunes for building SD cards, buts that's just me. Updated BS4 software allows 8G card. Not sure of spec.
