##### Adding files to the list:

There are 3 possibilities to add files to the list.

1. Select "Add folder (recursively)" or "Add files" in the menu "File".
2. Drag & Drop: Drag files from a file manager and drop them into the easyMP3Gain window.
3. Start easyMP3Gain with parameters. Some examples:

   easymp3gain '/home/song1.mp3' '/home/mymusic/' | adds song1.mp3 and all songs in /home/mymusic
   easymp3gain -r '/home/mymusic' | adds all songs in /home/mymusic recursively

##### MP3/AAC-Files vs. Ogg-Vorbis-Files:

MP3-Files are handled in an other way than Ogg-Vorbis-Files. The handling depends on the backends mp3gain and vorbisgain.

Mp3-Files can be analyzed and "hard-gained". In the analyze-process volume-tags are written in the mp3-file. The Column "Track Gain" shows, how much the file will be gained when clicking on "Gain". In this process the volume of the files is changed (hard-gained).

Vorbis-files can't be "hard-gained". If you click on "Gain" or "Analyze" the file is analyzed and the difference to 89dB is written in the file (only as a tag). Some media-players read this tag and adjust the volume. In contrast to "mp3gain" "vorbisgain" has a fixed reference at 89dB.

##### Example:

easyMP3Gain shows: Volume: 98.8; Gain: (-9.8).
This means, the file has a real volume of 98.8, but the player reads the gain-tag and adjusts the volume to: 98.8-9.8 = 89 dB!

##### Why is there a "?" in the "Album Volume" column?

There is no information about the album volume in ogg-vorbis files. Only the album-gain tags can be read.

##### Analyzing vs. Gaining Ogg-Vorbis-Files:

What's the difference between "Analyze" and "Gain" when working with ogg-files?
Nothing. When working with these files it doesen't matter whether you click on "analyze" or "gain". It's not necessary to run both of them.
