- > 100% - Amplify sound
For example:

- 200%: Double sound of original audio
- Output as WAV: Similar to instructions above, just click "WAV
Options" tab instead.
- Output as AAC: Similar to instructions above, just click "AAC

Click "Options" -> "MP3 Options" tab -> "ID3 tag"
section and check "Add ID3 tag", and then click "Edit ID3 tag"
button below to edit the custom ID3 tag information.

At "Title" field, if you check "Name as file name (not include extension)",
the software will set Title as file name when converting. For example: original
file name is "Happy New Year.ogg", and then the title will be set as "Happy New
Year" automatically.
Is it possible to output destination files to a specified
folder?
Yes, it is. You may click "Options" -> "General Options" tab

combo-box and click "Browse" button to choose an output folder.
Is it possible to output destination files to a specified
folder and keep directory tree of original files?
Yes, it is. Similar to question above, but you should check "Create folders
according to path of original file", thus the software will create folders
according to path of source file automatically when converting.
For example: Original file is "C:\Music\pop\sample.mp4" and
output folder is "D:\Output." If the option is checked, the output folder
will be "D:\Output\C\Music\pop."
How to split left and right channels into two files?
