It means that you can carry out audio normalization for a selected file in the added list. Also, the for a new list to be added, normalization values have to be specified again.
As the audio normalization is not a direct feature of this free audio player, it doesn’t helps in noise reduction or lossless quality, so I may warn you that you audio files may loose some quality after the task is completed.

I am sure that AIMP can prove a good software to be used both as an audio player and as volume normalizer software.
