We have found 9 software records in our database eligible for .m4a to .fla file format conversion.
Although you can convert M4A files to FLAC format (both .fla and .flac), the output file won't have the quality expected from lossless audio file.
This is due the fact that the M4A format already features lossy compression method and the resulting FLAC files will be of same (poor quality) compared to FLAC files created using the original tracks (or WAVs).
