What You Need:
CD Master - http://www.zittware.com/Products/products.html
Audacity - http://audacity.sourceforge.net/download/windows
Connection to a computer (Cable/Card Reader/Bluetooth)
Note: When downloading Audacity be sure to download the Lame Mp3 converter so that you can export your music

How To Do It:
Ok well I will start off with showing you how to get normal songs onto your fone so that they play properly.
Common errors that I have had with my e398 is that some songs won't play. This turned out to be due to the bitrate.
CD Master is a program that converts wavs to mp3s and such. While there are other functions to this software I will only cover the convertions in this tutorial.

Changing the Bitrate of a song:
Once you have installed CD Master, open it up and go to Record in the menu.
Select File Converions and then to MP3.
There are a lot of different functions in this to play around with but to keep it simple the only three buttons you need are the 'Change Defaults', 'Add Files' and 'OK' buttons.
So click on the 'Change Defaults button and select the 'WAV to MP3' tab.
The only thing you need to change in this area is the MP3 Bitrate (and perhaps the output directory).
Change the bitrate to 192.
Click ok and the rest is pretty simple.
Add the file you wish and then click OK.
Once the conversion is finished, click OK to the pop-up so that the temporary files are deleted.
Thats all for this part.

Changing Music To Your Liking:
Once you have installed Audacity, open the music that you wish to change. The file will be imported and then its time to play.
The program is pretty basic and self-explanitory.
To add an effect to the music, select the area of the music you wish to change and then apply the effect wanted.
There are many effects to use but my favorites are the fade-ins and fade-outs along with the pitch and echos.
This is a really fun program and I recommend you play around with it.
Once you have finished, export the file as an mp3 from the file menu.

Cheers and have fun
