== Intro ==
The wave shield is designed to play a very specific type of audio. If your music sample is in MP3 format, or 44KHz wav, you'll want to convert it to the right format. This way you will get the best sounding audio
Check the file
If you have a wave file already, you should check to see if its already in a proper format. That way you will save yourself some time! In windows, right-click on the file, and select '''Properties''' then click on the '''Summary''' tab

This file is 16KHz, 16-bit, mono PCM. Since thats below the maximum (22KHz, 16-bit, mono PCM) you are good to go. No need to convert the file
OK lets say the file is an MP3 or 44KHz or stereo wave file. We will need to convert it down.
== Option 1. Use iTunes ==
You can do the conversion easily with iTunes (available for Mac/Windows) if you have your music in iTunes already this will be super fast to convert multiple files!
You'll have to set the preferences first, but you only have to do it once

== Option 3. Use Audacity ==
If you dont have or don't want to use iTunes you can convert files (one at a time) with Audacity
This is pretty easy. You can use the free [http://audacity.sourceforge.net/ Audacity software] - available for windows, linux or mac
