Thanks for developing an excellent program in Mp3tag. I am running the latest version v2.42. I have discovered a problem displaying .m4a's that were encoded in Apple Lossless format. The files were originally in flac format. Mp3tag displays all pieces of the flac tag correctly. The flacs were converted with dBpoweramp to .m4a encoded with Apple Lossless codec. I know the tags were presevered by dBpoweramp when the flacs were converted. dBpoweramp displays the entire tag when you hold your mouse over any audio file. The tags are correct. Itunes also reads the .m4a Apple Lossless tags correctly.
This is the problem that Mp3tag is having. All columns display correctly from left to right until we reach the Codec column, it is blank. The Bitrate column displays "kBit/s". The Frequency column displays "Hz" and the Length displays "00.00". It would appear that some sort of shift has occurred. I have attached a zip file with a picture showing the problem. The first row in the picture is the flac file and the second row is the .m4a-(Apple Lossless) If you need sample files then I can provide them. Thanks for your support...
