Why is a .mp3 passed as an integer?

Maybe this is a really dumb question, but I went through a part of the R.java file. There I saw a mp3 file of my raw folder. It was named:

public static final int sound01=0x7f040000;

Why is a sound file passed as an integer? Is that just that they give the file a number, and then Android uses that number as a reference?

Thanks in advance!

This is just like any other reference that you access through R (e.g. R.string.x, R.dimen.x). You can access your files in raw through R.raw.x (so in this case, R.raw.sound01). The integer is just a guaranteed unique identifier for that particular resource.
