Very basic
Works, but not much more than that.
Converting a number of AIFF files to M4A while merging them does work but converting them to AAC does not. The files are not recognised as a valid audio file. When writing the converted and merged audio file, it’s not possible to specify a naming convention or even a name. The first file is saved as “01 Audio Track”. The second file as “01 Audio Track (copy)”. The thrid file becomes “01 Audio Track (copy 2)” and so on. There is no way to change that. Forget about any metadata tagging.
As I said, it mostly works, but there are no extras. You’ll have to pet the program along. If you would like to contact the developer about this, feel free, but brush up on your mandarin chinese.
