    AIFF tag editing drops samples

    Hi all,

    Downloaded some songs from Qobuz yesterday and before converting to FLAC with my personalised tags I added the "Source" tag in the raw AIFF files from Qobuz. While dBpoweramp was applying this tag I could see that the file sizes shrunk which led me to do a bit comparison between the files - have pasted it below. Looks like dBpa drops samples when applying this tag (or any other tag for that matter) but curiously not for ALL files. The first set consist of the files I have dragged into tunes to do some file tagging and then dragged out again to apply the Source tag with dBpa. The second set is the raw Qobuz downloads without anything applied.

    Log file:

    Differences found in 6 out of 11 track pairs.
