Thanks for your help! I think I'll convert to floating-point PCM to apply the volume change, and then feed the floating-point directly to Nero AAC encoder. Hopefully, if I understand these concepts correctly, this should not result in much quality loss, had I just encoded an originally correct-volume PCM to AAC.
I'll also try to contact ArcSoft about the incorrect decoding.
