Its simple,really
Follow each and every steps carefully and you'll get it done in no time!(maaaaybe~ xD)
Alright,lets start;
First-or do you preferably use Numbers?
1)Download the Latest Version(Currently Version 4.43.04) AND Version 4.30.06 (21.07.2010)
2)Install both versions(Which gets installed first doesn't matter),And then Download this Music Tempate
3)Open the Music.fdp with The Latest Version of Fmod Designer ,You will see a window like this;

4)On the left bar,those are the Music Folders,main_menu is for the login screen,lobby is the garage and so on.
You can add music to it by Drag and Dropping Music files into the Blue Button(Some are yellow) at the middle.
You can check what you added by double clicking the Blue(or yellow) Button in the middle.
Get to work From here!
5)Once done adding music,Save the project.
6)Now,open Fmod Designer Version 4.30.06.It will automatically Open your saved project.
7)Head over to the "Wave Banks",and Click music_bank03.Now look at the middle,there are a few settings,you are going to change "Bank Type to:Stream From Disk" and "Compression to Mp2",Make sure the Compression Quality is 50.

(The Waveforms are my project for the Persona Battle Music,you'll see your music inside it)
8)You are done here.Now press Build button on the top row,And press "Build Project"
A window will pop out and Set "Build Project For:PC" and tick "Music_Bank03" and press Build!
-Building will take some time depending how much music you added and how big it is.I Preferrably choose .OGG as my music extension as it is smaller.

9)Once done,check your template folder and you will see 2 files called "Music.fev" and "Music_bank03.fsb"
-Backup your "Music.fev" from World of Tanks\res\audio and then copy the 2 files into your World of Tanks\res\audio folder.Overwrite existing files.
10)All done!Get WoT Started!
Heres a Cake!
