Adding background music Ė Looping mp3 files using DirectX

Welcome to this final chapter on playing sounds using DirectX. This far weíve covered simply playing a .wav file, and playing a .wav file with an origin specified in 3D space. This chapter will add background music to our game.

Weíve already seen a way to do this: simply loading a big .wav file and play it using BufferPlayFlags.Looping. This would, however, require a huge .wav file (22MByte for 2 minutes of music), and thus a huge accompanying buffer variable. Although I havenít found a clear specification, my guess is you can only load .wav and .mid files into a SecondaryBuffer. Mid files are much smaller, but the quality is also extremely poor and they will sound different on every different computer.

The aim is clear: loading a long, small, yet high-quality sound file into our DirectX environment. An mp3 file would be perfect, but thereís no way to load this into DirectSound. Heck, after a few hours of research, I simply didnít find 1 page on the internet showing a way to load and loop an mp3 file using DirectX. But, as always, there IS a way, you simply have to try long enough.

The key is using Microsoft.DirectX.AudioVideoPlayback, so add a reference to it and put this line in your using-block:

 using Microsoft.DirectX.AudioVideoPlayback;

AudioVideoPlayback is a very small, simple DirectX module that allows you to play movies and audio very easily. 1 huge advantage: you can also load mp3 file :) So add this variable, to the top of your code:

 private Audio backmusic;

Weíll fill this variable in our InitializeSound method:

 backmusic = new Audio("music.mp3");
 backmusic.Play();

Make sure you download my music file here: (link). Itís the theme of one of the first flight simulators written for the first generation of mainstream 3D graphics cards, the 3Dfx VooDoo.

This code is even easier than using DirectSound! But we get less control.. A lot less. It isnít that trivial at all to let the music loop, or even detect when the music has stopped. However, one useful property of the Audio object we can read, is the current position in the music stream. If we know this, we know enough..

So add this variable to the top of your code:

 private double lastmusicposition;

Weíll store the current position of the music stream in this variable. If this hasnít changed, we know the music has stopped, and has to be started again. Thatís the idea behind the following code, which you can put at the end of the SoundAffairs method:

 if (backmusic.CurrentPosition == lastmusicposition)
 {
  backmusic.SeekCurrentPosition(0, SeekPositionFlags.AbsolutePositioning);
 }
 lastmusicposition = backmusic.CurrentPosition;

If the position hasnít changed, we set it to position 0, making our mp3 play all over again. In the end, we musnít forget to store our position in lastmusicposition, so itís ready to be read the next time!

Thatís all folks. You have the graphics, you have the movement, you have the sound, you have a game.
