Ok so basically i want to convert my FLAC music to AAC and then import it to iTunes. When i used Max.app i managed to export it but in iTunes the bitrate wasn't accurate. For example i exported my music at 256kbps but the most songs where in 255kbps. I know it is really stupid but it bugs me. So i used XLD. The problem with that app is that although the bitrate is accurate, it exports the songs in .m4u. From the little things i know, the actual extension for AAC is mp4 not m4u. Do you know how to fix any of these problems?
