Found a bug that seems to be persistant from older versions, but just noticed now.
When doing volume correction of files it appears it will not calculate volume on files with non standard names. An example would be Breña.mp3
There are no error messages or report, the track volume field just stays blank. if I change the same file to brena.mp3 it works fine.
Zortam allows me to edit and manipulate that same file in other ways without error.
I have downloaded a much newer version of mp3gain (perhaps zortam should update the included exe?)
If I feed the file to mp3gain it will calculate and work with the file fine.
The problem therefore appears to be a problem with zortam or the older version of mp3gain.exe that’s included.
