I have inherited several thousand tracks in various formats (MP3, MP4 and M4A). Fortunately the tagging seems to be fine in respect of title, album, artist, tracknumber etc.
I see also that they have been replaygained and itunenormed (in the main).
Problem is that the volumes are "all over the place" in iPod and Foobar some tracks being so loud as to be a problem.
Can someone suggest a solution.
Cheers
Edit: Tagging formats are ID3v1, ID3v2 and APE2
